Why GAO Did This Study:

A consolidated watch list managed by the FBI’s Terrorist Screening 
Center (TSC) contains the names of known or suspected terrorists, both 
international and domestic. Various agencies whose missions require 
screening for links to terrorism use watch list records. For example, 
U.S. Customs and Border Protection (CBP) screens travelers at ports of 
entry. Because screening is based on names, it can result in 
misidentifications when persons not on the list have a name that 
resembles one on the list. Also, some names may be mistakenly included 
on the watch list. In either case, individuals can be negatively 
affected and may express concerns or seek agency action, or redress, to 
prevent future occurrences. This report addresses: (1) the extent to 
which the numbers of misidentified persons are known and how they could 
be affected, (2) the major reasons misidentifications occur and the 
actions agencies are taking to reduce them or minimize their effects, 
and (3) the opportunities for redress available to individuals with 
watch list-related concerns. In conducting work at TSC and the 
principal federal agencies that use watch list data, GAO reviewed 
standard operating procedures and other relevant documentation and 
interviewed responsible officials.

GAO makes no recommendations at this time because the agencies have 
ongoing initiatives to improve data quality, reduce the number of 
misidentifications or mitigate their effects, and enhance redress 
efforts.

What GAO Found:

Annually, millions of individuals—from international travelers to visa 
applicants—are screened for terrorism links against the watch list. At 
times, a person is misidentified because of name similarities, although 
the exact number is unknown. In some cases, agencies can verify the 
person is not a match by comparing birth dates or other data with watch 
list records, but agencies do not track the number. In other cases, 
they ask TSC for help. From December 2003 (when TSC began operations) 
to January 2006, agencies sent tens of thousands of names to TSC, and 
about half were misidentifications, according to TSC. While the total 
number of people misidentified may be substantial, it likely represents 
a fraction of all people screened. Even so, misidentifications can lead 
to delays, intensive questioning and searches, missed flights, or 
denied entry at the border.

Misidentifications most commonly occur with names that are identical or 
similar to names on the watch list. To rapidly screen names against the 
watch list, agencies use computerized programs that account for 
differences due to misspellings and other variations. TSC has ongoing 
initiatives to improve computerized matching programs and the quality 
of watch list records. Also, CBP and the Transportation Security 
Administration (TSA) have established procedures designed to expedite 
frequently misidentified persons through screening, after confirming 
they are not on the watch list. 

Because security measures regrettably may cause personal 
inconveniences, TSA and CBP, with the support of TSC, provide 
opportunities for people who have been misidentified or mistakenly 
included on the watch list to seek redress. Most of these are 
misidentified persons who are not on the watch list but have a similar 
name and, therefore, may be repeatedly misidentified. Thus, TSA, for 
example, provides redress that relies heavily on efforts to expedite 
frequently misidentified persons through screening by allowing them to 
submit personal information that helps airlines more quickly determine 
that they are not on the watch list. If TSA and CBP cannot resolve 
questions from the public, they ask TSC for help. For 2005, TSC 
reported that it processed to completion 112 redress referrals and 
removed the names of 31 mistakenly listed persons from the watch list. 
To ensure that opportunities for redress are formally documented across 
agencies and that responsibilities are clear, the Justice Department is 
leading an effort to develop an interagency memorandum of understanding 
and expects a final draft to be ready for approval by fall 2006. TSC 
and frontline-screening-agency officials recognize that, after the 
agreement is finalized, the public needs to clearly understand how to 
express concerns and seek relief if negatively affected by screening. 
So, these officials have committed to making updated information on 
redress publicly available.

GAO provided a draft copy of this report to the departments of Justice, 
Homeland Security, and State. They provided technical clarifications 
that GAO incorporated where appropriate.

The Honorable F. James Sensenbrenner, Jr. 
Chairman:

The Honorable Bennie G. Thompson: 
Ranking Member: 
Committee on Homeland Security: 
House of Representatives:

To identify individuals with known or potential links to terrorism, 
since the tragedies of September 11, 2001, agencies such as the 
departments of State, Justice, and Homeland Security have implemented 
enhanced procedures to screen international travelers, airline 
passengers, and visa applicants. One important homeland security tool 
used by these federal frontline-screening agencies is the terrorist- 
screening database, otherwise known as the consolidated watch list, 
containing the names of individuals with known and suspected links to 
terrorism. The database, which contains names of foreign and U.S. 
citizens, is maintained by the Terrorist Screening Center, an entity 
that has been operational since December 2003 under the administration 
of the Federal Bureau of Investigation (FBI). Based upon agency- 
specific policies and criteria, relevant portions of the Terrorist 
Screening Center's consolidated watch list can be used in a wide range 
of security-related screening procedures. For instance, the 
Transportation Security Administration's No Fly and Selectee lists-- 
used by airlines to screen passengers prior to boarding--are portions 
of the Terrorist Screening Center's consolidated watch list.[Footnote 
1] Also, to help ensure that known or suspected terrorists do not enter 
the United States, applicable portions of the watch list are to be 
checked by Department of State consular officers before issuing U.S. 
visas and by U.S. Customs and Border Protection officers before 
admitting persons at air, land, and sea ports of entry.

Because terrorist watch list screening involves comparisons based on 
personal-identifying information such as names and dates of birth, 
there is potential to generate misidentifications--given that two or 
more persons, for example, may have the same or similar names.[Footnote 
2] As such, the screening inevitably can raise concerns from 
individuals who assert that they are being misidentified because of a 
name similarity to some other person whose name is on the watch list. 
Misidentifications can result in travel delays and other inconveniences 
for the respective individuals. Specific instances have been widely 
reported in newspapers and other media, including cases involving 
members of Congress and other high-profile individuals. 
Misidentifications highlight the importance of having a process--often 
referred to as redress--for affected persons to express their concerns, 
seek correction of any inaccurate data, and request other actions to 
reduce or eliminate future inconveniences.[Footnote 3] Similarly, such 
a process would apply to other persons affected by the maintenance of 
watch list data, including persons whose names are actually on the 
watch list but should not be ("mistakenly listed persons") as well as 
persons who are properly listed.[Footnote 4] Accordingly, in reference 
to terrorist watch list screening, this report addresses the following 
questions:

* To what extent are the numbers of terrorist watch list 
misidentifications known, and generally, how could misidentified 
persons be affected?

* What are the major reasons that misidentifications occur, and what 
actions are the Terrorist Screening Center and frontline-screening 
agencies taking to reduce the number of misidentified persons or 
expedite them through the screening process?

* To address concerns from misidentified and mistakenly listed persons, 
what opportunities for redress have the Terrorist Screening Center and 
frontline-screening agencies established?

In answering these questions, we reviewed the Terrorist Screening 
Center's standard operating procedures, statistics on watch-list- 
related screening encounters that resulted in referrals to the center, 
and other relevant documentation; and we interviewed Terrorist 
Screening Center officials, including the director, principal deputy 
director, chief information officer, and privacy officer. Similarly, we 
interviewed officials at and reviewed documentation obtained from the 
principal frontline-screening agencies--Transportation Security 
Administration, U.S. Customs and Border Protection, and the Department 
of State--whose missions most frequently and directly involve 
interactions with travelers.[Footnote 5] Regarding the screening of air 
passengers, in addition to contacting the Transportation Security 
Administration to broadly discuss the procedures of air carriers, we 
interviewed security officials at five major, domestic air carriers. 
Also, we visited various land and air ports of entry in four states-- 
California, Michigan, New York, and Texas. Collectively, these states 
have ports of entry on both the northern and southern borders of the 
United States. Regarding statistical data we obtained from the 
Terrorist Screening Center--such as the number of misidentifications 
and the results of the redress process, particularly the number of 
mistakenly listed persons whose names have been removed from the watch 
list--we discussed the sources of the data with center officials, 
including the chief information officer, and we reviewed documentation 
regarding the compilation of the statistics. We determined that the 
statistics were sufficiently reliable for the purposes of presenting 
overall patterns and trends. We performed our work from April 2005 
through August 2006 in accordance with generally accepted government 
auditing standards. Appendix I presents more details about our 
objectives, scope, and methodology.

Results in Brief:

Although the total number of misidentifications that have occurred as a 
result of watch-list-related screening conducted by all frontline- 
screening agencies and airlines is unknown, Terrorist Screening Center 
data indicate that about half of the tens of thousands of potential 
matches sent to the center between December 2003 and January 2006 for 
further research turned out to be misidentifications.[Footnote 6] The 
frontline-screening agencies and, in the case of air travel, airlines 
are able use other identifying information to resolve some possible 
matches without Terrorist Screening Center involvement, but when the 
agencies are unable to do so, they are to refer the information to the 
center for clarification and resolution. Frontline-screening agencies 
and airlines generally do not have readily available statistics 
quantifying the number of potential matches they have been able to 
resolve without consulting the Terrorist Screening Center. Although the 
total number of misidentified persons may be substantial in absolute 
terms, it likely represents a small fraction of the hundreds of 
millions of individuals screened each year. For example, in fiscal year 
2005, U.S. Customs and Border Protection alone reported that its 
officers managed about 431 million border crossings into the United 
States at land, air, and sea ports of entry. Nonetheless, 
misidentifications resulting from terrorist watch list screening can 
affect the respective individuals by, for example, delaying their 
travel, subjecting them to more intensive questioning and searches, and 
denying them conveniences such as self-serve check-in at airports. 
Also, in some cases, travelers have missed flights.

Misidentifications most commonly occur because the names of some 
persons being screened are similar to those on the terrorist watch 
list. The federal screening agencies we studied and most airlines use 
computer-driven algorithms to rapidly compare the names of individuals 
against the terrorist watch list.[Footnote 7] Generally, these name- 
recognition technologies may be designed to balance minimizing the 
possibility of false negatives--that is, failing to identify an 
individual whose name is on the terrorist watch list--while not 
generating an unacceptable number of false positives 
(misidentifications). Thus, the computerized algorithms may be 
configured to return a broad set of possible matches based on the name 
input in order to account, for example, for differences in names due to 
misspellings or transcription errors. The Terrorist Screening Center 
has formed an interagency working group to improve the effectiveness of 
identity matching across agencies, and the group's efforts were ongoing 
the time of our review. The center also has ongoing quality-assurance 
initiatives to identify and correct incomplete or inaccurate records 
that contribute to misidentifications. Further, agencies are taking 
actions to expedite frequently misidentified persons through the 
screening process. For example, in February 2006, U.S. Customs and 
Border Protection began annotating its database to help ensure that 
travelers who have been inadvertently stopped in the past--because they 
have the same or similar name as a watch list record--are no longer 
subjected to intensive screening, unless warranted by new data. As a 
future enhancement, the Terrorist Screening Center is planning to have 
links to other agencies' biometric data, such as fingerprints. 
According to center officials, the capability to link biometric data to 
supplement name-based screening may be more relevant for confirming the 
identities of known terrorists than minimizing misidentifications or 
false positives.

The Terrorist Screening Center, the Transportation Security 
Administration, and U.S. Customs and Border Protection have processes 
in place to help resolve concerns or complaints submitted by persons 
adversely affected by terrorist watch list screening.[Footnote 8] The 
processes are interdependent in that the frontline-screening agencies 
are to receive all redress queries, resolve those that, based on other 
identifying information, clearly involve misidentified persons, and 
refer the other queries to the Terrorist Screening Center--particularly 
queries submitted by persons whose names are actually contained on the 
watch list. For calendar year 2005, the center reported that it 
processed to completion 112 redress referrals and removed the names of 
31mistakenly listed individuals from the watch list. In contrast, the 
frontline-screening agencies processed thousands of redress queries. 
Most redress queries are submitted by misidentified persons, and their 
names cannot be removed from the watch list because they are not the 
persons on the list. Instead, some frontline-screening agencies have 
undertaken initiatives to expedite the future processing of persons who 
are frequently misidentified. For example, under the Transportation 
Security Administration's process, affected individuals can voluntarily 
provide additional personal-identifying information as a basis for the 
agency to determine whether their names can be put on a cleared list. 
Airlines are to use the cleared list to more quickly distinguish these 
individuals from persons who are on the No Fly and the Selectee lists. 
This procedure is intended to reduce delays in obtaining airline-
boarding passes. The Terrorist Screening Center, from its unique 
position as administrator of the consolidated terrorist watch list, has 
noted significant differences among agencies in providing watch-list-
related redress. For instance, whereas the Transportation Security 
Administration has designated an official accountable specifically for 
redress, U.S. Customs and Border Protection does not and also has not 
followed consistent procedures in referring appropriate redress queries 
to the Terrorist Screening Center. Thus, at the Terrorist Screening 
Center's request, the Department of Justice is leading an effort to 
develop an interagency memorandum of understanding to ensure that 
opportunities for redress are formally documented and that agency 
responsibilities are clear, with designated officials specifically 
accountable for supporting the continued success of watch-list-related 
redress. This effort, according to the Terrorist Screening Center, has 
been ongoing since fall 2005, and a final draft of the memorandum of 
understanding is expected to be ready for interagency clearances by 
fall 2006. The Department of Justice and the Terrorist Screening Center 
have acknowledged that, upon finalization of an interagency agreement 
that documents the redress opportunities and designates agencies' 
responsibilities, it is important that appropriately updated 
information on redress and points of contact be made available to the 
public, including updates of Web- based guidance.

We are not making recommendations at this time because the agencies 
have ongoing efforts to improve data quality and otherwise either 
reduce the number of misidentifications or mitigate their effects and 
to provide more effective redress.

Background:

In April 2003, we reported that watch lists were maintained by numerous 
federal agencies and that the agencies did not have a consistent and 
uniform approach to sharing information on individuals with possible 
links to terrorism.[Footnote 9] Our report recommended that the 
Department of Homeland Security's Secretary, in collaboration with the 
heads of the departments and agencies that have and use watch lists, 
lead an effort to consolidate and standardize the federal government's 
watch list structures and policies. Subsequently, pursuant to Homeland 
Security Presidential Directive 6, dated September 16, 2003, the 
Terrorist Screening Center was established to consolidate the 
government's approach to terrorism screening and provide for the 
appropriate and lawful use of terrorist information in screening 
processes. The center began "24/7" operations on December 1, 2003, and, 
about 3 months later, on March 12, 2004, announced that watch list 
consolidation was completed with establishment of the terrorist- 
screening database. This consolidated database is the U.S. government's 
master repository for all known and suspected international and 
domestic terrorist records used for watch-list-related screening. 
Records for inclusion in the consolidated database are submitted to the 
Terrorist Screening Center from the following two sources:

* Identifying information on individuals with possible international 
terrorism ties is provided through the National Counterterrorism 
Center, which is managed by the Office of the Director of National 
Intelligence.

* Identifying information on individuals with ties to purely domestic 
terrorism, such as Ted Kaczynski (the "Unabomber"), is provided by the 
FBI.

In their terrorist-screening processes, the three federal frontline- 
screening agencies that we reviewed use records exported by the 
Terrorist Screening Center. That is, the applicable exported records 
are incorporated, respectively, into the Transportation Security 
Administration's No Fly and Selectee lists, U.S. Customs and Border 
Inspection's Interagency Border Inspection System, and the State 
Department's Consular Lookout and Support System. The following listing 
discusses the frontline-screening agencies' use of watch list records 
more specifically:

* Transportation Security Administration's No Fly and Selectee Lists: 
As needed, the Transportation Security Administration provides updated 
No Fly and Selectee lists to airlines for use in prescreening 
passengers. Through the issuance of security directives, the agency 
requires that airlines use these lists to screen passengers prior to 
boarding. The agency's Office of Intelligence (formerly called the 
Transportation Security Intelligence Service) provides assistance to 
airlines in determining whether passengers are a match with persons on 
the lists.[Footnote 10]

* U.S. Customs and Border Protection's Interagency Border Inspection 
System: U.S. Customs and Border Protection officers use the Interagency 
Border Inspection System to screen travelers entering the United States 
at ports of entry, which include land border crossings along the 
Canadian and Mexican borders, sea ports, and U.S. airports for 
international flight arrivals. This system includes not only the 
applicable records exported by the Terrorist Screening Center, but also 
additional information on people with prior criminal histories, 
immigration violations, or other activities of concern that U.S. 
Customs and Border Protection wants to identify and screen at ports of 
entry.

* State Department's Consular Lookout and Support System: This system 
is the primary sensitive but unclassified database used by consular 
officers abroad to screen the names of visa applicants to identify 
terrorists and other aliens who are potentially ineligible for visas 
based on criminal histories or other reasons specified by federal 
statute. According to the State Department, all visa-issuing posts have 
direct access to the system and must use it to check each applicant's 
name before issuing a visa.

Also, the Terrorist Screening Center makes applicable records in the 
consolidated database available to support the terrorist-screening 
activities of other federal agencies--such as U.S. Immigration and 
Customs Enforcement, which is the largest investigative component of 
the Department of Homeland Security--as well as state and local law 
enforcement agencies. For example, the FBI's National Crime Information 
Center has a file--the Violent Gang and Terrorist Organization File-- 
which is accessible by federal, state, and local law enforcement 
officers for screening in conjunction with arrests, detentions, or 
other criminal justice purposes.[Footnote 11] A subset of this file 
consists of the Terrorist Screening Center's records to be used to 
screen for possible terrorist links.

Figure 1 presents a general overview of the name-matching process 
typically used by frontline-screening agencies and airlines to screen 
individuals against applicable records exported by the Terrorist 
Screening Center, which has an important role in verifying identities. 
When the computerized name-matching system of a frontline-screening 
agency or, in the case of air travel, an airline generates a "hit" (a 
potential name match) against a terrorist database record, the agency 
or airline is to review each potential name-match. Any obvious 
mismatches (misidentifications) are to be resolved by the frontline 
agency or airline.

Conversely, clearly positive or exact matches generally are to be 
referred to the applicable screening agency's intelligence center and 
to the Terrorist Screening Center to provide law enforcement an 
opportunity for a counterterrorism response.[Footnote 12] Similarly, 
hits involving inconclusive matches--that is, uncertain and other hard- 
to-verify potential matches--typically are to be referred to the 
applicable screening agency's intelligence center. In turn, if the 
intelligence center cannot conclusively determine whether a hit is an 
exact match, the Terrorist Screening Center is to be 
contacted.[Footnote 13] Referring inconclusive matches to the Terrorist 
Screening Center for resolution or confirmation is important because 
the possible consequences of not identifying a known or suspected 
terrorist could be worse than the inconveniences associated with 
misidentifications. In conducting its research, the Terrorist Screening 
Center has access to classified data systems that may contain 
additional information not available to the referring agency. Once the 
Terrorist Screening Center has confirmed the individual as either a 
positive match or a misidentification, the frontline-screening agency 
is to be informed.

Homeland security-related screening processes entail some level of 
inconvenience for all travelers. Also, in an operational context, 
people can be and frequently are screened for reasons not related to 
the terrorist watch list but rather for reasons related to an agency's 
mission. For example, U.S. Customs and Border Protection screens 
travelers for any conditions that may make them inadmissible to the 
country, including past violations of immigration, drug, customs, or 
other laws. The agency also randomly selects certain individuals for 
more thorough screening. Similarly, prospective airline passengers may 
be randomly selected for additional screening, and others may be 
selected if they exhibit unusual behavior.[Footnote 14] Generally, 
screening agencies and airlines are not to disclose the reason they 
select an individual for more thorough screening measures, so persons 
may mistakenly assume it is because they are on a terrorist watch list.

Although Likely a Small Percentage of All People Screened, the 
Thousands of Persons Misidentified to the Terrorist Watch List Can 
Experience Additional Questioning, Delays, and Other Effects:

Annually, hundreds of millions of individuals--international travelers, 
airline passengers, and visa applicants--are screened against relevant 
portions of the Terrorist Screening Center's consolidated watch list. 
The number of persons misidentified during terrorist watch list 
screening may be substantial in absolute terms but likely represents a 
small fraction of the total screenings. Nonetheless, misidentifications 
resulting from terrorist watch list screening can affect the respective 
individuals in various ways, with perhaps the most common situation 
involving delays and related inconveniences experienced by travelers.

Although a Substantial Number, Misidentified Persons Likely Constitute 
a Small Percentage of All People Screened:

Although the full universe of persons misidentified by terrorist watch 
list screening may be substantial in absolute terms, the total number 
likely represents a small fraction of all persons who are screened. 
During the 26-month period we studied--from December 2003 (when the 
Terrorist Screening Center began operations) to January 2006--the 
center received tens of thousands of screening-encounter referrals from 
frontline-screening agencies and determined that approximately half 
involved misidentified persons with names the same as or similar to 
someone whose name was contained on the terrorist watch list. The 
number of referrals to the Terrorist Screening Center does not 
constitute the universe of all persons initially misidentified by 
terrorist watch list screening because the names of many persons 
initially misidentified are not forwarded to the Terrorist Screening 
Center. Rather, by comparing birth dates or other data, the frontline- 
screening agencies (e.g., U.S. Customs and Border Protection) are able 
to resolve many initial misidentifications without contacting the 
Terrorist Screening Center. Additionally, for air passengers, the 
airlines often are able to resolve initial misidentifications without 
contacting the Transportation Security Administration.[Footnote 15] The 
screening agencies and airlines generally do not maintain readily 
available statistics on these resolutions.

Nonetheless, although the full universe of such misidentifications may 
be substantial in absolute terms, the total number likely represents a 
small fraction of all persons who are subject to terrorist watch list 
screening procedures, as in the following examples:

* U.S. Customs and Border Protection reported that its officers managed 
a total of 431 million border crossings into the United States at land, 
air, and sea ports of entry in fiscal year 2005.

* Domestic airline flights--flights within the United States--carried 
658 million passengers during the 12 months ending January 2006, 
according to Department of Transportation statistics.[Footnote 16]

* The State Department reported that it processed about 7.4 million 
nonimmigrant visa applications in fiscal year 2005.[Footnote 17]

In addition to these international travelers, domestic flight 
passengers, and visa applicants, any other person can be subject to 
terrorist watch list screening in conjunction with routine law 
enforcement activities. For instance, in stopping a motorist for a 
traffic violation, a state or local law enforcement officer can check 
the motorist's name against the National Crime Information Center's 
various files, which include terrorist watch list records exported by 
the Terrorist Screening Center. The National Crime Information Center, 
according to the FBI, is available to virtually every law enforcement 
agency nationwide, 24 hours a day, 365 days a year.

Misidentified Individuals Can Experience Delays and Other Effects:

People who are misidentified to the terrorist watch list can be 
affected in various ways, most commonly experiencing delays and related 
inconveniences, including being subjected to more intensive questioning 
and searches. Generally, the extent of the effects of terrorist watch- 
list-related misidentification can vary by individual circumstances and 
the operational nature of the screening agency's mission. For example, 
an individual with a name similar to someone who is on the 
Transportation Security Administration's No Fly list likely will be 
unable to utilize the convenience of Internet, curbside, and airport 
kiosk check-in options. This effect of misidentifications is reflected 
in a sample of 24 complaint letters to the Transportation Security 
Administration that we reviewed.[Footnote 18] Many of the complainants 
described their frustrations with not being able to use alternative 
check-in options such as the Internet or airport kiosks. Similarly, in 
a survey conducted in June 2006 by the National Business Travel 
Association, many companies' travel managers responded that their 
employees have expressed frustration about repeatedly having to go to 
the airline ticket counter to obtain a boarding pass.[Footnote 19]

Also, misidentifications can cause other effects, such as missed 
airline flights by either leisure travelers or business travelers, 
which could have economic and other consequences, although we found no 
readily available data on how frequently these effects occurred. 
However, according to Transportation Security Administration data, two 
international flights--one in December 2004 and another in May 2005-- 
were diverted from landing at their scheduled destinations in the 
United States due to potential matches to the No Fly list. In each 
instance, following the diversions of the flights and further 
investigation after the airplanes landed, federal authorities 
determined that the respective passengers were misidentified and not 
true matches to the No Fly list. Nonetheless, the diversions resulted 
in delays and related inconveniences for all passengers on these 
flights.

The Transportation Security Administration has acknowledged that 
misidentifications can be embarrassing and time consuming for 
individuals and also potentially can erode the public's confidence in 
the agency's security efforts. Similarly, a recent Department of 
Homeland Security report recognized that "individuals who are 
mistakenly put on watch lists or who are misidentified as being on 
these lists can potentially face consequences ranging from 
inconvenience and delay to loss of liberty."[Footnote 20]

Also, an individual can experience an immediate delay at a port of 
entry when U.S. Customs and Border Protection's automated search of the 
Interagency Border Inspection System database returns a potential match 
to a terrorist watch list record. For such potential matches, U.S. 
Customs and Border Protection's operating protocol is to escort the 
person to another screening area for further questioning and inspection 
(a process referred to as secondary screening). The length of time the 
person spends in secondary screening can be several hours, depending 
partly on the difficulty or ease of verifying whether the person is or 
is not the individual on the watch list. In the four states we visited-
-California, Michigan, New York, and Texas--U.S. Customs and Border 
Protection officers told us that given the importance of the homeland 
security mission, their practice is to err on the side of caution by 
conducting very thorough screenings.[Footnote 21]

The effects of such misidentifications and the related secondary 
screenings can be emotional as well as physical, as reflected in 
complaint letters to U.S. Customs and Border Protection. A sample of 28 
complaint letters to U.S. Customs and Border Protection that we 
reviewed alleged a range of effects, such as experiencing travel 
delays, which resulted in missing airline flights and incurring 
additional travel costs; being subjected to extensive questioning and 
searches, while not being allowed to contact family members, friends, 
or business associates to inform them about the delays; and feeling 
embarrassed and frustrated.[Footnote 22]

The State Department's screening of nonimmigrant visa applicants 
against the terrorist watch list may not affect individuals in the same 
way as does screening by the Transportation Security Administration and 
U.S. Customs and Border Protection. Generally, the State Department's 
screening differs from other screening agencies because there is more 
time to search records and make decisions. According to State 
Department officials, the average time for processing a nonimmigrant 
visa application is about 2 days. However, additional processing time 
may be needed if initial screening of the applicant shows a possible 
link to terrorism--that is, the applicant's name possibly matches that 
of a person whose name is on the terrorist watch list. The officials 
explained that this additional processing time is needed because a 
decision on the visa applicant cannot be made until a security advisory 
opinion is obtained. That is, the consular post must ask the Department 
of State headquarters in Washington, D.C., to initiate a process of 
requesting that various agencies check their respective databases or 
systems for the existence of any investigative or intelligence 
information regarding the individual and pass the results back to a 
central point. This interagency review process includes the FBI, the 
Drug Enforcement Administration, the Central Intelligence Agency, and 
others. According to State Department officials, visa applicants are 
routinely told not to buy tickets or incur other travel-related 
expenses until the clearance process has been completed and the 
application approved.

In acknowledging that the interagency review process may extend the 
processing time for a visa decision, the State Department provided us 
(in June 2006) the following contextual perspectives:

* In the last 2 years, the department and its interagency partners have 
worked to decrease the processing time in order to reduce the impact on 
the traveling public.

* Nevertheless, the department's position is that the time it takes to 
screen a visa applicant is a necessary part of the application 
procedure and, therefore, is not an adverse governmental action. At 
times, additional processing must be done in order to determine whether 
a visa applicant is eligible for a visa under the law, including for 
national security reasons. The additional processing is the 
inconvenient consequence of the proper functioning of the visa 
screening system.

* Moreover, the extended processing time generally is a one-time 
occurrence. Once an alien is cleared through the process, the clearance 
is noted in the department's consular visa database. Thus, this person 
may not be subject to the same processing delay when applying for 
another visa in the future, unless additional investigative or 
intelligence information arises after issuance of the first 
visa.[Footnote 23]

Screening by state and local law enforcement also differs from 
screening by the Transportation Security Administration, U.S. Customs 
and Border Protection, and the State Department. Essentially, federal 
agencies (or air carriers, as applicable) initiate screening when 
individuals make an airline reservation, arrive at a port of entry, or 
apply for a visa. In contrast, a state or local law enforcement agency 
may initiate screening by, for example, pulling over a motorist for 
speeding. Generally, a routine procedure for the law enforcement 
officer is to query the motorist's name against records in the National 
Crime Information Center, which contains criminal history records as 
well as terrorist watch list records. According to congressional 
testimony presented in March 2004 by the Director of Public Security 
for the State of New York, it takes about 12 to 15 minutes, on average, 
for a New York patrol officer to contact the Terrorist Screening Center 
and resolve a potential name match.[Footnote 24] More recently, in July 
2006, the Director of the Terrorist Screening Center told us that the 
average time nationally is now down to about 5 minutes--that is, the 
time period beginning with the center's receipt of the call from a 
state or local law enforcement officer and ending with the response to 
the officer regarding the potential name match.[Footnote 25]

Most Misidentifications Occur Because of Similarities to Names on the 
Terrorist Watch List; Agencies Are Attempting to Reduce the Incidence 
of Misidentifications or Otherwise Facilitate Individuals through the 
Screening Process:

The most common cause of misidentifications is similarity of the names 
of persons being checked to names on the Terrorist Screening Center's 
consolidated watch list, for which there is no complete remedy, but 
agencies are taking actions to minimize the effect on frequently 
misidentified persons. The Terrorist Screening Center has formed an 
interagency group to improve the effectiveness of identity matching 
across agencies and also has ongoing initiatives regarding data 
quality. As a future enhancement, the Terrorist Screening Center's 
strategy is to develop the capability to link name-based watch list 
searches to relevant biometric systems maintained by other agencies, 
although this capability may be more useful for confirming positive 
matches than for reducing the incidence of misidentifications.

Misidentifications Result Because a Traveler's Name Is Similar to 
Someone with a Terrorist Watch List Record:

Misidentifications occur most often because the names of some persons 
being screened are the same or similar to those in the consolidated 
terrorist watch list. To handle the large volumes of travelers and 
others who must be screened, federal agencies and most airlines use 
computer-driven algorithms to rapidly compare the names of individuals 
against the applicable terrorist watch list records. A primary factor 
in designing a computerized name-matching process is the need to 
minimize the possibility of generating false negatives--that is, 
failing to identify an individual whose name is on the terrorist watch 
list--without generating an unacceptable number of false positives 
(misidentifications). To help ensure that name-based screening does not 
miss detecting someone who is on the watch list, agencies and airlines 
may configure their algorithms in such a way that they return a broad 
set of possible matches for any given name input. For instance, the 
computerized algorithms may account for differences in names due to 
misspellings or transcription errors.

Operationally, for each name that is screened against the watch list, 
the computerized algorithm may return a list of possible matches. If 
applicable, screening agency or airline security personnel then review 
these results of possible matching records arrayed by probability 
scores to determine which, if any, is a positive match with the person 
being screened. To help ensure awareness of best practices among 
agencies, the Terrorist Screening Center has formed and chairs a 
working group--the Federal Identity Match Search Engine Performance 
Standards Working Group--which met initially in December 2005.[Footnote 
26] An objective of the working group is to provide voluntary guidance 
for federal agencies that use identity-matching search engine 
technology. Essentially, the prospective guidance is intended to 
improve the effectiveness of identity matching across agencies by, 
among other means, assessing which algorithms or search engines are the 
most effective for screening specific types or categories of names. At 
the time of our review, a target date for completing the initiative to 
develop and provide voluntary guidance to screening agencies had not 
been set.

Some Misidentifications Can Result from Inaccurate or Incomplete Data:

Some misidentifications can result from inaccurate or incomplete data 
in the consolidated terrorist watch list. Generally, the FBI and 
intelligence agencies are the original collectors of the information 
used to determine whether a given individual should be added to the 
terrorist watch list. The Terrorist Screening Center, in turn, is 
responsible for ensuring that information received from the 
intelligence community is accurately maintained in the consolidated 
watch list. One of the Terrorist Screening Center's primary goals is to 
maintain accurate and complete information.

In June 2005, the Department of Justice's Office of the Inspector 
General reported that its review of the Terrorist Screening Center's 
consolidated watch list found several problems--such as inconsistent 
record counts and duplicate records, lack of data fields for some 
records, and unclear sources for some records.[Footnote 27] Among other 
things, the Inspector General recommended that the Terrorist Screening 
Center develop procedures to regularly review and test the information 
contained in the consolidated terrorist watch list to ensure that the 
data are complete, accurate, and non-duplicative. The Terrorist 
Screening Center agreed and noted that it was taking steps to implement 
the recommendation. Also, the Terrorist Screening Center has quality- 
assurance initiatives ongoing to identify and correct troublesome 
records related to misidentifications.

Moreover, the Terrorist Screening Center's director and principal 
deputy director stressed to us that quality of data is a high priority 
for the center and also is a continuing challenge, particularly given 
that the database is dynamic, changing frequently with additions, 
deletions, and modifications. The officials noted the equal importance 
of ensuring that (1) the names of known and appropriately suspected 
terrorists are included in the watch list and (2) the names of any 
mistakenly listed individuals are removed. In this regard, the 
officials explained that the center's standard operating practices 
include at least two opportunities to review records. First, Terrorist 
Screening Center staff--including subject matter experts detailed to 
the center from other agencies--review each incoming record submitted 
(nominated) to the center for inclusion in the consolidated watch list. 
Also, every time there is a screening encounter--for example, a port- 
of-entry screening of an individual that generates an actual or a 
potential match with a watch list record--that record is reviewed again.

In addition to the Terrorist Screening Center's quality-assurance 
initiatives, screening agencies also have been looking at ways to 
reduce misidentifications. One way that holds promise, where 
applicable, is to use additional personal-identifying information to 
enhance name-based searching. For example, as part of its efforts to 
develop the Secure Flight program, the Transportation Security 
Administration conducted tests between November 2004 and April 2005 to 
determine what combinations of names and associated personal- 
identifying attributes were most effective in matching airline 
passenger data against terrorist watch list records. According to the 
Transportation Security Administration, the testing indicated that 
searches using additional personal-identifying attributes could 
potentially result in decreasing the number of misidentifications. 
However, the Transportation Security Administration concluded that more 
testing was needed to determine, among other things, the point of 
diminishing returns in using combinations of personal-identifying 
information to enhance name-based watch list searches.

Agencies Are Taking a Number of Actions to Expedite Frequently 
Misidentified Persons through the Screening Process:

In addition to initiatives aimed at reducing the number of 
misidentifications, screening agencies also are taking actions to 
expedite the screening of frequently misidentified persons.

Transportation Security Administration Maintains a Cleared List of 
Individuals to Expedite Screening and Mitigate Negative Effects:

The Transportation Security Administration has instituted a process 
designed to help frequently misidentified air passengers obtain 
boarding passes more quickly and avoid prolonged delays. Under this 
process, an individual can voluntarily provide the Transportation 
Security Administration with additional personal-identifying 
information. Then, the Transportation Security Administration will use 
this information to decide whether the person's name should be put on a 
cleared list--that is, a list that contains the names and other 
personal-identifying information of individuals who have been checked 
and cleared as being persons not on the No Fly and Selectee lists. 
Airlines are to use the cleared list to more quickly determine that 
these passengers are not the persons whose names are on the No Fly and 
Selectee lists. As needed, the Transportation Security Administration 
provides the airlines with updates of the No Fly and Selectee lists and 
the cleared list. As discussed later in this report, the cleared list 
is integral to the Transportation Security Administration's redress 
process for watch-list-related complaints.

U.S. Customs and Border Protection Is Annotating Its Database to Help 
Frequently Misidentified Travelers Avoid Additional Screening and 
Delays:

According to U.S. Customs and Border Protection officials, the agency 
has implemented procedures designed to help frequently misidentified 
travelers avoid additional screening and delays. Specifically, in 
February 2006, the agency began annotating its database regarding 
travelers who were inadvertently stopped because they have the same or 
similar name as a watch list record but are not the actual subject of 
the record. The officials explained that the agency uses the data 
routinely collected on a traveler during the initial inspection 
process, and no further action is necessary by the traveler. The 
officials noted that these travelers should no longer be stopped on 
subsequent visits because of the records in question. As of September 
2006, according to U.S. Customs and Border Protection officials, the 
agency had annotated more than 10,300 such instances and had prevented 
more than 7,200 unnecessary inspections from occurring. [Footnote 28]

The Department of State Is Annotating Its Database to Avoid Future 
Delays for Visa Applicants:

As mentioned previously, the State Department's processing of a visa 
application takes additional time if initial screening shows a possible 
link to terrorism, because a decision on the visa applicant cannot be 
made until a security advisory opinion request is forwarded to 
Washington, D.C., and a response is received. However, the State 
Department has taken steps to help minimize visa-processing delays for 
any subsequent application filed by a previously screened person. 
Specifically, according to State Department officials, when a visa 
applicant is screened through the security advisory opinion process and 
is found to be a person who is not on the terrorist watch list, the 
State Department enters clarifying comments in its database or even on 
the visa itself. This information is available for review by consular 
officers in processing any subsequent visa applications filed by the 
individual. Thus, according to State Department officials, the 
individual's future applications should not incur any additional 
processing times, unless new information has been acquired in the 
interim period that would cast doubt on the applicant's eligibility for 
a visa.

As a Future Enhancement, the Terrorist Screening Center Plans to Have 
Links to Biometric Data; Various Traveler-Screening Programs Already 
Use Biometric Data:

Within the law enforcement community, fingerprint identification has 
been used and accepted for decades and is the de facto international 
standard for positively identifying individuals. Thus, as is widely 
recognized throughout government, the use of biometric technologies 
based on fingerprint recognition, facial recognition, or other 
physiological characteristics offer opportunities for enhancing the key 
homeland security objective of preventing known or suspected terrorists 
from entering the country.[Footnote 29]

Conceptually, biometrics can be used to screen a traveler against a 
consolidated database, such as the terrorist watch list--a screening of 
one record against many records. However, the Terrorist Screening 
Center presently does not have this capability, although use of 
biometric information to supplement name-based screening is planned as 
a future enhancement. Specifically, the Terrorist Screening Center's 
strategy is not to replicate existing biometric data systems. Rather, 
the center's strategy, according to the director and principal deputy 
director, is to develop a "pointer" capability to facilitate the online 
linking of name-based searches to relevant biometric systems, such as 
the FBI's Integrated Automated Fingerprint Identification System 
(IAFIS)--a computerized system for storing, comparing, and exchanging 
fingerprint data in a digital format, which contains the largest 
criminal biometric database in the world. Center officials recognize 
that even biometric systems have screening limitations, such as 
relevant federal agencies may have no fingerprints or other biometrics 
to correlate with many of the biographical records in the center's 
consolidated database. For instance, watch list records may be based on 
intelligence gathered by electronic wire taps or other methods that 
involve no opportunity to obtain biometric data. Also, the availability 
of interoperable technology to facilitate online linking among agencies 
is a long-standing issue that presents challenges. Nonetheless, center 
officials anticipate that biometric information, if available, can be 
especially useful for confirming matches to watch list records when 
individuals use false identities or aliases.

On the other hand, the Terrorist Screening Center has no plans for 
trying to reduce the incidence of misidentifications by collecting or 
maintaining biometric information on persons who are not on the watch 
list. Center officials noted that collecting and using biometric 
information on innocent persons would raise significant privacy 
concerns, which would have to be thoroughly considered in interagency 
discussions and weighed against the possible benefits.

Presently, the Department of Homeland Security uses biometric data for 
operating various programs to screen travelers, one of which is a 
required-enrollment program for selected foreign nationals who travel 
to the United States and others are voluntary-enrollment or trusted- 
traveler programs. However, enrollment in these programs, whether 
required or voluntary, does not exempt individuals from being screened 
against the terrorist watch list. As mentioned previously, for 
instance, the watch list is dynamic, changing frequently with 
additions, deletions, and modifications.

The required-enrollment program that uses biometric data is the U.S. 
Visitor and Immigrant Status Indicator Technology (US-VISIT) program, 
which is an entry/exit tracking system designed to collect, maintain, 
and share information on selected foreign nationals who travel to the 
United States. The program uses a related system--the Automated 
Biometrics Identification System (IDENT), developed by the former 
Immigration and Naturalization Service--to collect two fingerprints 
(right and left index fingers) and a digital photograph to provide for 
the biometric identification of visitors.[Footnote 30] Required 
enrollment in the US-VISIT program is conducted by the Department of 
State at visa-issuing consulates before the visitors depart or by U.S. 
Customs and Border Protection at ports of entry when the visitors 
arrive. American citizens, permanent legal residents, Canadian 
nationals, and Mexican nationals with border-crossing cards are not 
required to submit to US-VISIT screening at ports of entry. In July 
2006, the Department of Justice's Office of the Inspector General 
provided an update on progress toward achieving biometric 
interoperability between IDENT and IAFIS.[Footnote 31] The Inspector 
General's progress report noted that the FBI and the Department of 
Homeland Security have formed a working group to make US-VISIT, IDENT, 
and IAFIS interoperable by December 2009.

Under the US-VISIT program, at each subsequent reentry into the United 
States, applicable individuals are biometrically screened against the 
fingerprints collected during the initial enrollment. Such biometric 
screening is for identity verification purposes--screening that 
involves a one-to-one matching of fingerprints to determine if the 
traveler is the person enrolled in the program. Enrollment in the U.S.- 
VISIT program does not exempt individuals from being screened against 
the terrorist watch list and generally may not reduce the possibility 
of the individuals being misidentified based on name similarities. As 
such, when there are potential matches to a name on the watch list, the 
individuals may still be subject to more extensive screening at ports 
of entry.

Another biometrics-based program--Registered Traveler--is being pilot 
tested by the Transportation Security Administration.[Footnote 32] The 
program, commonly categorized as a trusted-traveler program, collects 
biographical information and biometric data from airline passengers who 
volunteer to undergo a security threat assessment. The pilot program is 
being tested in partnership with selected airlines and airports across 
the country. Under the program, prior to boarding at airports, 
participants are to be screened using the biometric data.

In addition, U.S. Customs and Border Protection operates various 
trusted-traveler programs, which are intended to provide expedited 
processing for pre-approved, low risk travelers who frequently cross 
U.S. borders. For instance, a commuter program on the southern border 
is known as Secure Electronic Network for Travelers Rapid Inspection 
(SENTRI) and on the northern border as "NEXUS." For these voluntary 
programs, the biometric component generally involves only the 
enrollment process, such as conducting fingerprint-based background 
checks using IDENT or IAFIS to ensure that applicants are eligible for 
expedited processing before allowing their participation.[Footnote 33] 
Thereafter, cross-border commuting is facilitated by use of radio 
frequency identification (RFID) technology, whereby an embedded chip in 
each membership card transmits the person's arrival to a reader-antenna 
at the port of entry.[Footnote 34]

While trusted-traveler programs are most commonly applicable to cross- 
border commuters, U.S. Customs and Border Protection officials told us 
that all persons who believe they are frequently misidentified with 
similar names on the terrorist watch list can apply and will be 
accepted if they are found to meet program requirements. Also, a 
benefit of these programs from a watch list perspective is that U.S. 
Customs and Border Protection has greater assurance of the identity of 
the enrollees and that these individuals are not persons on the watch 
list. Enrollment in a trusted-traveler program does not exempt 
individuals from being screened against the terrorist watch list; 
although, according to U.S. Customs and Border Protection officials, 
enrollment does mitigate the possibility of the individuals being 
misidentified and selected for more extensive screening at ports of 
entry. The officials also noted that the trusted-trusted traveler 
programs are not widely applicable to all ports of entry. Rather, the 
programs are helpful only to individuals eligible to use trusted- 
traveler lanes at the border, not at airports or seaports.

The Terrorist Screening Center and Frontline-Screening Agencies Are 
Addressing Concerns Related to Watch List Screening, and an Interagency 
Agreement Is Being Developed to Further Ensure an Effective Means for 
Seeking Redress:

It is important that individuals who are inadvertently and adversely 
affected by watch list screening be provided an opportunity to seek 
redress. The Terrorist Screening Center, the Transportation Security 
Administration, and U.S. Customs and Border Protection have processes 
in place to address individuals' concerns involving watch-list-related 
screening and have reported some successes, such as removing from the 
watch list the names of several mistakenly listed persons. Most watch- 
list-related redress concerns usually involve misidentified persons-- 
individuals who are not on the watch list but have name similarities 
with known or suspected terrorists. To help ensure that opportunities 
for redress are formally documented and that agency responsibilities 
are clear, the Department of Justice is leading an effort to develop an 
interagency memorandum of understanding. A final draft of the 
memorandum of understanding is expected to be ready for interagency 
clearances by fall 2006, according to Terrorist Screening Center 
officials.

The Terrorist Screening Center and the Federal Frontline-Screening 
Agencies Have a Role in Addressing the Concerns of Individuals Who are 
Adversely Affected by Watch List Screening:

The Terrorist Screening Center, the Transportation Security 
Administration, and U.S. Customs and Border Protection have important 
responsibilities in providing individuals who are inadvertently and 
adversely affected by watch list screening with opportunities to seek 
redress. As mentioned previously, all aggrieved individuals may seek 
redress, including persons who express concerns or complaints that they 
are being misidentified and adversely affected because they have a name 
similar to someone whose name is on the terrorist watch list and 
persons who actually are on the terrorist watch list. Any such concern 
or complaint raised formally by an affected individual is what the 
Terrorist Screening Center calls a redress query. Specifically, the 
Terrorist Screening Center defines a "redress query" as communication 
from individuals or their representatives inquiring or complaining 
about an adverse experience during a terrorist watch-list-related- 
screening process conducted or sponsored by a federal agency, including 
congressional inquiries to federal agencies on behalf of constituents.

According to the Terrorist Screening Center's standard operating 
procedures for redress matters, frontline-screening agencies, such as 
the Transportation Security Administration and U.S. Customs and Border 
Protection, have a key role in handling redress queries. Significantly, 
for example, the frontline-screening agencies--and not the Terrorist 
Screening Center--are to receive and initially handle redress queries 
from the public. The operating procedure of having frontline agencies 
receive redress queries serves at least two purposes, according to the 
Terrorist Screening Center. First, the applicable frontline-screening 
agency is better positioned to know the details of the screening 
encounters and to respond appropriately. Second, many screening 
encounters may be based on factors other than terrorism--factors such 
as narcotics trafficking or incomplete currency or customs 
declarations--which are not within the mission of the Terrorist 
Screening Center and must be resolved by the frontline agencies. Also, 
as a practical matter, the frontline agencies are the entities visible 
to complainants or inconvenienced persons.

Further, after a frontline-screening agency receives a complaint or 
concern from an individual, the agency is to begin its internal 
complaint-resolution or redress process. As part of this process, the 
agency is to determine whether the person's complaint is related to a 
potential match to a terrorist watch list record. If the determination 
is "no"--that is, the person is not actually on the watch list but was 
misidentified because of a name similarity to someone who is on the 
terrorist watch list--the frontline-screening agency is responsible for 
resolving the complaint and responding to the misidentified individual.

If the frontline-screening agency's determination is "yes"--which 
includes not only definite matches but also any potential or "maybe" 
matches that require additional research to confirm--the frontline 
agency is to refer the redress query to the Terrorist Screening Center. 
Then, the center is to check its database to determine whether the 
individual is indeed on the terrorist watch list or whether the person 
is misidentified with someone on the watch list. If the person is 
actually on the terrorist watch list, the Terrorist Screening Center is 
to consult with applicable intelligence community and law enforcement 
agencies to assess whether the person is appropriately listed and 
should remain on the watch list or is mistakenly listed and should be 
removed from the list. In either instance, the center is to inform the 
applicable frontline-screening agency, which is responsible for 
responding to the individual. If the complainant is a misidentified 
person, the Terrorist Screening Center is to send the redress query 
back to the applicable frontline-screening agency for that agency to 
resolve. Also, as part of its quality-assurance efforts, the center is 
to review the underlying watch list record that caused the person's 
adverse experience to determine, for example, the record's validity or 
whether a modification is needed, including possible removal of the 
record. Finally, any referrals received by the Terrorist Screening 
Center not related to its mission--that is, "other issues" with no 
nexus to terrorism such as complaints involving employee misconduct or 
random screening--are to be sent back to the applicable frontline- 
screening agency, which is to provide a response to the individual.

In January 2005, the Terrorist Screening Center established its formal 
redress process. An overview of the redress process, including 
interaction between the center and the frontline-screening agencies, is 
illustrated in figure 2.

Figure 2: General Overview of the Terrorist Screening Center's Process 
for Handling Concerns Involving Watch-List-Related Screening:

[See PDF for image]

Source: GAO.

Note: As a general overview, the figure does not reflect all ways that 
complaints or concerns can be resolved. For instance, regarding 
clearance difficulties experienced by an individual at a port of entry, 
U.S. Customs and Border Protection may determine that the person was 
selected for intensive screening based on information provided by 
another federal law enforcement agency. If so, U.S. Customs and Border 
Protection may refer the complainant's query to the applicable agency-
-which, in turn, would reply directly to the individual.

[End of figure]

The Terrorist Screening Center does not directly provide final 
disposition letters to individuals who have submitted redress queries. 
Rather, the center works with the frontline-screening agencies--and, as 
applicable, any relevant intelligence or law enforcement agencies--to 
develop a written response. In providing a final response to an 
individual who submits a redress query, the frontline-screening 
agencies use a response letter that neither confirms nor denies the 
existence of any terrorist watch list records relating to the 
individual. For example, one of the Transportation Security 
Administration's standardized response letters states, in part, "Where 
it has been determined that a correction to records is warranted, these 
records have been modified to address any delay or denial of boarding 
that you may have experienced as a result of the watch list screening 
process."

Generally, this type of language reflects the Terrorist Screening 
Center's policy of neither confirming nor denying whether an individual 
is on the consolidated terrorist watch list because this information is 
derived from classified and sensitive law enforcement and intelligence 
sources. The policy of nondisclosure to the public is intended to 
protect the operational counterterrorism and intelligence collection 
objectives of the government and the personal safety of those involved 
in counterterrorism investigations.

The Terrorist Screening Center's Handling of Redress Referrals Has 
Resulted in Removing the Names of Several Mistakenly Listed Persons 
from the Terrorist Watch List:

During calendar year 2005, the Terrorist Screening Center processed to 
completion 112 redress queries referred by frontline-screening 
agencies. Of this total, according to the Terrorist Screening Center, 
31 were determined to be mistakenly listed individuals and their names 
were removed from the watch list (see table 1). The center reported 
that for another 54 queries the individuals were on the terrorist watch 
list and the center either did not change the watch list records (48) 
or made some updates (6).

Table 1: Number and Disposition of Redress Queries Referred to the 
Terrorist Screening Center, Calendar Year 2005:

Disposition of redress query: Positive match: The name of the 
mistakenly listed person was removed from the watch list; Number: 31[A].

Disposition of redress query: Positive match: No change to the watch 
list record was needed; Number: 48.

Disposition of redress query: Positive match: The record was changed or 
updated but not removed from the watch list; Number: 6.

Disposition of redress query: Misidentification: The redress query was 
referred back to the frontline-screening agency to process and provide 
a response to the individual; Number: 19.

Disposition of redress query: Other: These queries involved issues not 
relevant to the terrorist watch list and should not have been referred 
to the Terrorist Screening Center; Number: 8.

Disposition of redress query: Total; Number: 112.

Source: Terrorist Screening Center data.

[A] According to Terrorist Screening Center officials, the center was 
already in the process of removing a few of these names before the 
center received the respective redress queries. The officials explained 
that although the names were properly included on the watch list 
initially, subsequent events warranted removing the names.

[End of table]

Also, as table 1 indicates, 19 of the 112 referrals in calendar year 
2005 involved misidentified persons--that is, the Terrorist Screening 
Center determined that these individuals were not on the terrorist 
watch list but have names similar to someone who is a known or 
suspected terrorist. The center referred each of these queries back to 
the applicable frontline-screening agency for processing under the 
respective agency's redress procedures. These 19 misidentifications do 
not constitute the annual universe of all redress queries involving 
misidentifications. Rather, thousands of such queries from 
misidentified persons are handled by the frontline-screening agencies 
and are not referred to the Terrorist Screening Center.

To enhance public awareness of redress availability, the Web site of 
the FBI--the Terrorist Screening Center's administering agency-- 
presents an overview of applicable policy and procedures, provides 
answers to frequently asked questions, and gives contact information 
for three frontline-screening agencies--the Transportation Security 
Administration, U.S. Customs and Border Protection, and the State 
Department. This information is also presented in appendix II of this 
report.

Most Redress Queries Involve Misidentified Persons and Are Handled by 
Frontline-Screening Agencies:

Most redress queries involve misidentified rather than mistakenly 
listed individuals. Therefore, inherently the disposition or resolution 
of a redress query involving a misidentification cannot be removal of 
the individual's name from a watch list because the individual is not 
the person on the list. Instead, an objective of the frontline- 
screening agencies is to address complaints of misidentified 
individuals by providing alternative relief--that is, by developing 
procedures and having sufficient information in screening databases to 
expedite the processing of frequently misidentified persons.

Transportation Security Administration: For Individuals Who Are 
Frequently Misidentified Due to Name Similarities with Known or 
Suspected Terrorists, the Agency Has Compiled a Cleared List:

The Transportation Security Administration has a contact center that 
centrally receives nonmedia public inquiries and complaints. According 
to the agency, the contact center's customer service representatives 
and contact security specialists are trained to handle and analyze 
incoming calls, e-mails, correspondence, and facsimiles from the 
public, the Congress, and private industry. The functions of these 
representatives and specialists, as specified in the contact center's 
operating procedures, are to analyze letters and electronic messages, 
sort them by subject matter, and confer with appropriate offices 
throughout the agency (including field staff) to provide responses.

Generally, any inquiries and complaints regarding watch-list-related 
screening--that is, screening against the No Fly and Selectee lists-- 
are to be handled by the agency's Office of Transportation Security 
Redress, which was established in November 2004.[Footnote 35] As part 
of the redress process, an individual can voluntarily provide 
additional personal-identifying information to the Office of 
Transportation Security Redress. Specifically, the individual can 
submit a completed Traveler Identity Verification Form (reproduced in 
app. III), along with a copy of a U.S. passport or copies of three 
types of other identification documents, such as birth certificate, 
driver's license, military identification card, military discharge 
paper, voter registration card, and naturalization certificate or 
certificate of citizenship.[Footnote 36] Then, the agency will use this 
information in deciding whether the person's name should be put on a 
cleared list--which airlines are to use for distinguishing the 
individual from persons who are in fact on the No Fly or Selectee 
lists.[Footnote 37] Along with as-needed updates of the No Fly and 
Selectee lists, the Transportation Security Administration transmits 
updated cleared list information to the airlines for the purpose of 
enabling the airlines to more quickly determine that these passengers 
are not the persons who are on the No Fly and Selectee lists. The 
purpose of the cleared list is to mitigate or minimize delays or other 
inconveniences by facilitating the check-in process for passengers who 
have names similar to known or suspected terrorists. An individual on 
the cleared list may still have to obtain a boarding pass at the ticket 
counter rather than using Internet, curbside, or airport kiosk check-in 
options. Nonetheless, the intent of the cleared list is to reduce the 
delay or wait time for applicable air passengers in obtaining a 
boarding pass at the ticket counter.

According to the Director of the Office of Transportation Security 
Redress, over 30,000 individuals had submitted identify verification 
forms and supporting documentation to the agency, as of December 2005, 
and the names of the overwhelming majority of these individuals were 
added to the cleared list. The director explained that although the 
agency requires air carriers to use the cleared list, responsibility 
for utilizing the list rests with the air carriers, and all carriers do 
not operate in the same way or have equal capabilities. Further, 
according to the director, some customers (air passengers) call and 
complain about having problems even though they have taken the 
necessary steps to be placed on the cleared list. The director said 
that his office forwards information regarding these complaints to 
another component of the agency--the Office of Transportation Sector 
Network Management--which is responsible for contacting the respective 
air carriers to address relevant issues.

According to Transportation Security Administration officials, the 
Secure Flight program is a prospective solution to current issues 
regarding inconsistent use of the cleared list by air carriers--as well 
as any inconsistent use of the No Fly and Selectee lists. Under the 
Secure Flight program, the Transportation Security Administration plans 
to take over, from commercial airlines, the responsibility for 
comparing identifying information of airline passengers against 
information on known or suspected terrorists.[Footnote 38] We note, 
however, that the Transportation Security Administration has been in 
the process of developing a passenger prescreening system, presently 
known as the Secure Flight program, for more than 3 years. We have 
reported and the Transportation Security Administration has 
acknowledged significant challenges in developing and implementing the 
Secure Flight program.[Footnote 39] Earlier this year, the 
Transportation Security Administration suspended Secure Flight's 
development to reassess, or rebaseline, the program. The rebaselining 
effort includes reassessing the program goals to be achieved, the 
expected benefits and capabilities, and the estimated schedules and 
costs. As of July 2006, the Transportation Security Administration had 
not publicly announced any decisions regarding the future of the Secure 
Flight program, although the agency anticipates that the rebaselining 
effort will be completed by the end of September 2006.

U.S. Customs and Border Protection Is Considering Realigning Its Watch- 
List-Related Redress Responsibilities and Is Updating Its Procedures:

U.S. Customs and Border Protection headquarters has a Customer 
Satisfaction Unit that functions as a centralized source for recording, 
tracking, and reviewing all complaint information related to U.S. 
Customs and Border Protection interactions with travelers, the general 
public, industry, and government entities. This unit is responsible for 
responding to customer complaints, irrespective of the subject matter-
-that is, the unit focuses on all complaint topics, not just complaints 
involving terrorist watch-list-related screening. For instance, U.S. 
Customs and Border Protection routinely uses a comment card that allows 
travelers to express any complaint regarding the port-of-entry 
processing experience. U.S. Customs and Border Protection policy is to 
provide a comment card to (1) all air and sea travelers who are 
subjected to a secondary examination and (2) all air, land, and sea 
travelers who undergo a personal search.

In June 2006, U.S. Customs and Border Protection officials explained 
that the agency was actively considering ways to enhance the capability 
of the Customer Satisfaction Unit to support redress efforts regarding 
terrorist watch-list-related concerns or complaints. For instance, a 
realignment being considered is to move the responsibility for handling 
certain categories of complaints--those not involving terrorist watch 
list screening--from the Customer Satisfaction Unit to the Office of 
Public Affairs. Also, the officials further noted that the agency's 
Office of Regulations and Rulings was updating the Customer 
Satisfaction Unit's standard operating procedures, including redress 
procedures regarding terrorist watch-list-related concerns or 
complaints.

Further, in commenting on a draft of this report in September 2006, 
U.S. Customs and Border Protection officials said that the agency is 
working with the Terrorist Screening Center to ensure that its process 
aligns with the center's process. Also, another Department of Homeland 
Security component--U.S. Immigration and Customs Enforcement-- 
commented that its Office of Intelligence serves as a point of contact 
and works closely with the Terrorist Screening Center's redress team to 
ensure the removal or modification of records, as appropriate, from the 
terrorist-screening database and the Treasury Enforcement 
Communications System/Interagency Border Inspection System. For 
instance, U.S. Immigration and Customs Enforcement noted that if the 
Terrorist Screening Center determines that an individual should no 
longer be listed in the terrorist-screening database, the Office of 
Intelligence coordinates with U.S. Customs and Border Protection to 
have the record expunged from the Treasury Enforcement Communications 
System/Interagency Border Inspection System.

As part of our study, we reviewed the Federal Bureau of Investigation's 
Web site for the Terrorist Screening Center to determine what overview 
information regarding watch-list-related redress was publicly available 
(see app. II). In turn, from the FBI's overview Web site, we followed 
up on any references or online links to the redress processes of key 
frontline-screening agencies--the Transportation Security 
Administration and U.S. Customs and Border Protection.

In contrast to the online link to the Transportation Security 
Administration's redress guidance (see app. III), we found limited 
usefulness in the online link to U.S. Customs and Border Protection's 
redress guidance. The FBI's overview Web site lists the Customer 
Satisfaction Unit as the redress-related contact point for U.S. Customs 
and Border Protection. Also, the overview Web site provides an online 
link to a fact sheet describing the Interagency Border Inspection 
System--a system that provides U.S. Customs and Border Protection and 
other law enforcement entities with access to computer-based 
information. However, the fact sheet (reproduced in app. IV) has no 
specific guidance regarding terrorist-watch-list-related redress. 
Rather, the fact sheet answers basic questions regarding the 
Interagency Border Inspection System, such as who uses the system and 
what information is in the system. Moreover, the overview Web site 
provides no references or online links to U.S. Customs and Border 
Protection's trusted-traveler programs--such as SENTRI and NEXUS. As 
mentioned previously, agency officials told us that persons who believe 
they are frequently misidentified with the terrorist watch list or who 
continuously experience delays and other inconveniences during 
screening could apply to one of these programs and, if accepted, 
receive expedited processing at applicable ports of entry.

Based on our observations regarding the limited usefulness of the 
online links from the FBI's overview Web site, U.S. Customs and Border 
Protection officials acknowledged a need to coordinate with the FBI and 
the Terrorist Screening Center to provide more appropriate online links 
regarding redress guidance. The officials noted, for example, that U.S. 
Customs and Border Protection's Web site does provide information 
regarding the Customer Satisfaction Unit and how complaints are handled 
as well as information on trusted-traveler programs.

Department of State: Applicants Who Are Denied a Visa Have No Legal 
Basis to Appeal, but an Agency-Initiated Process Is Used to Remove 
Erroneous or Outdated Entries from the Consular Lookout and Support 
System:

The term "redress," according to the State Department, is not 
applicable to complaints about visa denials, which are final decisions 
not subject to appeal or judicial review. However, the State Department 
has an agency-initiated process for removing erroneous or outdated 
entries from the Consular Lookout and Support System, which contains 
applicable terrorist watch list records. As mentioned previously, the 
system is used by consular officers abroad to screen the names of visa 
applicants to identify terrorists and other aliens who are potentially 
ineligible for visas based on criminal histories or other reasons 
specified by federal statute. All visa-issuing posts have direct access 
to the system and are required to use it to check each applicant's name 
before issuing a visa, according to the State Department.

The Immigration and Nationality Act of 1952, as amended, gives 
Department of State consular officers at overseas posts exclusive 
authority for adjudicating applications submitted by foreign citizens 
for visas to enter the United States.[Footnote 40] The process for 
determining who will be issued or refused a visa consists of several 
steps--including checking or cross-referencing each applicant's name 
against the Consular Lookout and Support System, which contains 
applicable names and biographical data exported from the Terrorist 
Screening Center's database. According to the State Department, no 
applicant is denied a visa simply because the person's name appears in 
the Consular Lookout and Support System, which is only a flag or tool 
to help the consular officer know if further screening may be required. 
Rather, visa denials are by law based either on statutory grounds of 
ineligibility, which are specifically set out in the Immigration and 
Nationality Act, as amended,[Footnote 41] or on the applicant's failure 
to present evidence to establish eligibility for the type of visa 
requested. In addition to security and terrorism concerns, statutory 
grounds of ineligibility include, for example, criminal history 
reasons, previous violations of immigration law, and health-related 
grounds.

According to State Department instructions provided to consular offices 
worldwide, visa denials are to be reviewed by the consular officer's 
supervisor. If an error has been made or a question exists about 
interpreting immigration law in reference to the facts surrounding the 
applicant, the consular officer can request a legal advisory opinion. 
Also, if there are misunderstandings about the application process, 
individuals can correspond with the overseas consular section and the 
Public Inquiries Division of the Visa Office in Washington, D.C.

However, federal courts have consistently held that a consular 
officer's final decision to issue or deny a visa is not subject to a 
formal appeal or to judicial review.[Footnote 42] That is, there is no 
way to directly appeal the visa denial, nor is there a way to directly 
overturn the consular officer's denial decision because it is not 
subject to judicial review. Thus, in explaining why it would be 
incorrect and legally misleading to use the term "redress" in reference 
to any complaint about a visa denial, officials in the State 
Department's Bureau of Consular Affairs commented that a visa refusal 
(denial) is a final decision in which the consular officer makes a 
legal determination that the applicant is not eligible for a visa based 
on a statutory ground. The State Department officials reiterated that 
the consular officer's decision is a final governmental adjudication, 
for which there is no appeal or judicial review, and the only recourse 
for the person is to submit a new application with sufficient 
information to "overcome" the grounds for ineligibility.

Consular officers are required to provide each applicant an explanation 
of the legal basis for denying the visa.[Footnote 43] However, if the 
basis for ineligibility is terrorism--under section 212(a)(3)(B) of the 
Immigration and Nationality Act, as amended[Footnote 44]--the consular 
officer normally would not be able to explain the reasons behind the 
denial because of national security grounds.

According to Bureau of Consular Affairs officials, the State Department 
does have an agency-initiated process for removing erroneous or 
outdated information from the Consular Lookout and Support System. In 
explaining why the correction-of-records process is initiated by the 
agency and not the visa applicant, the officials commented 
substantially as follows:

* Visa applicants usually would not even know whether their names are 
on the terrorist watch list. If a visa application results in the 
overseas post's requesting a security advisory opinion and additional 
screening, the applicant might think that any processing delay is due 
to a record entry in the Consular Lookout and Support System. However, 
the additional screening could be due to reasons other than terrorism, 
such as a criminal record, a contagious disease, or simply an overstay 
on a previous visa.

* Thus, any deletion of entries from the Consular Lookout and Support 
System normally would be initiated by the consular officer in the 
field. That is, if the consular officer determines--based on evidence 
presented during the course of a visa application--that an entry in the 
Consular Lookout and Support System is incorrect or has been overtaken 
by events, the officer is to initiate action to have the entry deleted 
from the system.

Also, the Bureau of Consular Affairs officials noted that there has 
been an occasional complaint that despite the issuance of a visa, the 
alien experienced difficulties at a U.S. port of entry because, for 
example, screening by U.S. Customs and Border Protection showed a 
potential match with a terrorist watch list record. Regarding these 
instances, the officials said that based on an interest in data 
integrity and customer service, the department works with the Terrorist 
Screening Center to review relevant records and determine an 
appropriate course of action, which could consist of a watch list 
message or annotation specifying that the alien is not a person on the 
watch list. In addition, as discussed previously, the State Department 
is taking steps to annotate its database when it screens individuals 
and finds that they are not on the watch list. Such annotations are 
intended to expedite visa processing in the future and limit the 
incidence of misidentifications.

The Department of Justice Is Leading an Effort to Finalize an 
Interagency Agreement to Help Ensure That Effective Redress Is 
Available:

The Terrorist Screening Center and the frontline-screening agencies 
have interdependent responsibilities in providing redress for 
individuals who are inadvertently and adversely affected by watch list 
screening. The availability of redress is important for all affected 
persons, including persons who are misidentified because of name 
similarities and to persons who contend that they are mistakenly 
included on the terrorist watch list. For any given watch-list-related 
complaint or redress query, providing relief can necessitate 
interaction among several governmental agencies. For instance, if the 
query involves a person who is mistakenly listed, relevant redress 
participants could include the Terrorist Screening Center and a 
frontline-screening agency as well as the agency that originally 
submitted or nominated the person's name for inclusion in the 
consolidated terrorist watch list. Nominating agencies include the FBI 
and various agencies within the intelligence community, such as the 
Central Intelligence Agency, the Defense Intelligence Agency, and the 
National Security Agency.

To help ensure that opportunities for terrorist-watch-list-related 
redress are implemented effectively, the Department of Justice is 
leading an effort--which has been ongoing since fall 2005--to develop 
and finalize an interagency memorandum of understanding. Key purposes 
of the final memorandum of understanding include ensuring that 
opportunities for redress are formally documented and that agency 
responsibilities are clear, with designated officials accountable for 
supporting the continued success of the processes. The Department of 
Justice has a lead role in developing the memorandum of understanding 
because the Terrorist Screening Center has primary responsibility for 
the consolidated terrorist-screening database. Interagency partners in 
the effort to develop the memorandum of understanding include the 
Department of Homeland Security, the Department of State, and the 
National Counterterrorism Center.

Also, another entity involved in developing the memorandum of 
understanding is the Privacy and Civil Liberties Oversight Board, which 
is part of the Executive Office of the President and consists of five 
members appointed by the president.[Footnote 45] According to the 
board's executive director, the terrorist watch list redress process is 
a top priority for the board. The executive director noted that since 
June 2006 board staff have attended all meetings of the interagency 
partners engaged in developing the memorandum of understanding. This 
official opined that the board's participation has helped reprioritize 
this matter among the constituent agencies and that the board is 
committed to continuing its involvement.

According to Department of Justice officials, a final draft of the 
memorandum of understanding is expected to be ready for interagency 
clearances by fall 2006. Terrorist Screening Center officials 
emphasized that the interagency memorandum of understanding was 
definitely needed, particularly as a mechanism for ensuring the 
accuracy of the watch list. The center officials noted, for instance, 
that there have been disagreements at times between agencies over 
nominations to the watch list. Thus, in handling watch-list-related 
complaints, the center officials explained that the interagency 
memorandum of understanding could help by clearly outlining a process 
for coordinating with the National Counterterrorism Center and 
nominating agencies to validate the accuracy and appropriateness of 
watch list records.

Moreover, the Terrorist Screening Center officials explained that the 
interagency memorandum of understanding could help resolve significant 
watch-list-related redress differences among the frontline-screening 
agencies. Examples regarding Department of Homeland Security components 
are as follows:

* The Transportation Security Administration has an office specifically 
designated for redress issues, with an accountable official--the 
Director, Office of Transportation Security Redress. Also, the office 
has followed consistent procedures in referring appropriate watch-list- 
related complaints to the Terrorist Screening Center.

* In contrast, U.S. Customs and Border Protection does not have a 
clearly designated official accountable for redress, and the agency has 
not always followed consistent procedures in referring appropriate 
watch-list-related complaints to the Terrorist Screening Center.

Additionally, regarding the State Department, the Terrorist Screening 
Center officials stressed the importance of having clearly established 
procedures and responsibilities. The center officials noted that even 
though the State Department's operational context is somewhat different 
than that of other frontline-screening agencies, the department 
nonetheless has a substantial volume of interactions with the Terrorist 
Screening Center. State Department Bureau of Consular Affairs officials 
acknowledged to us the value of having an interagency memorandum of 
understanding that specifies standard operating procedures for redress 
and designates points of contact. In this regard, the State Department 
officials commented that they have been participating in meetings with 
the Terrorist Screening Center and other interagency partners to 
discuss the proposed memorandum of understanding. According to the 
officials, a benefit to the State Department expected from the 
interagency agreement would be clearly established and coordinated 
procedures for removing--from the department's Consular Lookout and 
Support System and the Terrorist Screening Center's consolidated watch 
list--any name that is mistakenly listed or has been overtaken by 
subsequent events.

Concluding Observations:

Homeland security measures affect all travelers to some extent. Thus, 
it may be argued that travel delays and other inconveniencies resulting 
from terrorist watch-list-related screening can be viewed as 
regrettable but inevitable consequences of enhanced security. However, 
name-based screening and its inherent limitations--even full names, in 
most cases, are hardly unique identifiers--may result in 
disproportionate impact on individuals who repeatedly are singled out 
for additional screening for no other reason than the similarity of 
their names to someone on the watch list.

The Terrorist Screening Center and its interagency partners are 
undertaking a number of efforts, including data-quality initiatives, to 
reduce the occurrence and/or impact of watch list screening on U.S. 
citizens and visitors who do not necessarily merit additional scrutiny 
and the associated inconveniences. A continuing challenge for the 
center will be ensuring that the consolidated watch list contains 
accurate data, particularly given that the database is dynamic, 
changing frequently with additions, deletions, and modifications. The 
efforts of an interagency working group to improve the effectiveness of 
name-matching computer algorithms may offer some promise for reducing 
the number of people who experience unintended, adverse effects. 
However, any policy trade-off considerations regarding use of 
algorithms likely will favor ensuring homeland security over minimizing 
inconveniences to travelers. Regarding future operations, the Terrorist 
Screening Center is actively considering approaches for using biometric 
data to supplement name-based searches, although the availability of 
appropriate technology is an issue that has long confronted the 
interagency screening community.

In any event, despite the best efforts of the interagency community to 
maintain a fully accurate watch list and to conduct screening 
efficiently, there likely will be continuing unintended consequences. 
Thus, it is appropriate for the Terrorist Screening Center and its 
interagency partners to continue their efforts to provide effective 
redress for both mistakenly listed persons and misidentified persons. 
Indeed, redress queries have already resulted in the removal of several 
mistakenly listed names from the watch list. Comparatively, however, 
the issue of redress arises more commonly regarding the thousands of 
persons who are not on the watch list but are misidentified and 
adversely affected because of a name similarity. Whether appropriate 
relief is being afforded these individuals is still an open question, 
for several reasons. For example, although a core element of the 
redress provided by the Transportation Security Administration is the 
maintenance of a cleared list, there are some indications that the 
cleared list is not working as intended to reduce delays for air 
passengers in obtaining boarding passes. Prospectively, the 
Transportation Security Administration expects that development and 
implementation of the Secure Flight program will help ensure consistent 
and effective use of the cleared list among air carriers, although the 
agency has not publicly disclosed its future plans for the program.

Another frontline-screening agency's initiative, U.S. Customs and 
Border Protection's database-annotation initiative, may prove to be an 
even more efficient approach for assisting frequently misidentified 
individuals. Unlike the Transportation Security Administration's 
cleared list procedures, the U.S. Customs and Border Protection's 
initiative is based on records in the agency's database and does not 
necessitate any filing of forms and other documentation by travelers. 
At the time of our review, U.S. Customs and Border Protection was 
planning to develop a capability to monitor the effectiveness of the 
initiative. This planning effort is particularly important, given that 
the initiative may eventually prove to be a model for a proactive 
solution if it functions as intended.

Finally, an overarching factor regarding whether appropriate relief is 
being afforded to persons inadvertently and adversely affected by 
terrorist watch-list-related screening is the absence of an interagency 
agreement to help ensure that, among other matters, redress procedures 
and responsibilities are clearly documented and implemented 
effectively. The Terrorist Screening Center and its interagency 
partners are working to address this fundamental deficiency and have 
indicated their intent to provide the public with updated information 
on the availability of redress, after finalization of an agreement.

We are not making recommendations at this time because the agencies 
have ongoing efforts to improve data quality and otherwise either 
reduce the number of misidentifications or mitigate their effects and 
to provide more effective redress.

Agency Comments:

We provided a draft of this report for comments to the departments of 
Homeland Security, State, and Justice. We received written responses 
from each agency.

In its response, the Department of Homeland Security acknowledged that 
it currently is undertaking actions to enhance terrorist-screening and 
redress efforts. Also, the response noted that in January 2006, the 
departments of State and Homeland Security announced an initiative on 
"Secure Borders and Open Doors in the Information Age," otherwise known 
as the Rice-Chertoff Initiative. One purpose of the initiative is to 
establish a governmentwide redress process to address perceived 
problems in international and domestic traveler prescreening. According 
to the Department of Homeland Security, a goal is to establish a one- 
stop redress process for travelers by the end of calendar year 2006. 
The department explained that this initiative, which will supplement 
terrorist watch-list-related redress, focuses on a larger set of travel-
screening redress issues. The full text of the Department of Homeland 
Security's written comments is reprinted in appendix V. The department 
also provided technical comments, which we incorporated in this report 
where appropriate.

The Department of State commented that the report accurately describes 
the visa process and the department's position that the administrative 
processing time required to screen a visa applicant--including, if 
required, the processing of a security advisory opinion review--is a 
necessary part of the visa application procedure rather than an adverse 
governmental action. Also, the department noted that--in its use of the 
terrorist watch list as a screening tool for visa adjudication--a 
"misidentification" is not an adverse result for the visa applicant. 
Rather, according to the department, this type of response helps to 
determine that the visa applicant is not associated with terrorism. In 
its written response, the department also provided a technical comment 
regarding the security advisory opinion process, which we incorporated 
in this report where appropriate. The full text of the Department of 
State's written comments is reprinted in appendix VI.

The Department of Justice provided technical comments only, which we 
incorporated in this report where appropriate.

As arranged with your offices, unless you publicly announce the 
contents of this report earlier, we plan no further distribution until 
30 days after the date of this report. At that time, we will send 
copies of this report to interested congressional committees and 
subcommittees. We will also make copies available to others on request. 
In addition, this report will be available at no charge on GAO's Web 
site at http://www.gao.gov.

If you or your staff have any questions about this report or wish to 
discuss the matter further, please contact me at (202) 512-8777 or

Appendix I: Objectives, Scope, and Methodology:

Objectives:

In response to a request from the Chairman of the House Judiciary 
Committee and the Ranking Member of the House Committee on Homeland 
Security, we addressed the following questions:

* To what extent are the numbers of terrorist watch list 
misidentifications known, and generally, how could misidentified 
persons be affected?[Footnote 46]

* What are the major reasons that misidentifications occur, and what 
actions are the Terrorist Screening Center and frontline-screening 
agencies taking to reduce the number of misidentified persons or 
expedite them through the screening process?

* To address concerns from misidentified and mistakenly listed persons, 
what opportunities for redress have the Terrorist Screening Center and 
frontline-screening agencies established?[Footnote 47]

Scope and Methodology:

Our work generally focused on the screening of travelers, although the 
terrorist watch list is used for a variety of other screening purposes, 
such as conducting background checks of workers who have access to 
secure areas of the national transportation system. In performing our 
work, we focused on the Terrorist Screening Center and three frontline- 
screening agencies--the Transportation Security Administration, U.S. 
Customs and Border Protection, and the Department of State--whose 
missions most frequently and directly involve interactions with 
travelers. At the Terrorist Screening Center, we interviewed key 
officials--including the director, principal deputy director, chief 
information officer, and privacy officer--and reviewed standard 
operating procedures and other relevant documentation.

Regarding the screening of air passengers against the No Fly and 
Selectee lists prior to boarding, in addition to contacting the 
Transportation Security Administration to broadly discuss the 
procedures of air carriers, we interviewed security officials at five 
major, domestic air carriers. At their request, the air carriers are 
not identified in this report. Regarding U.S. Customs and Border 
Protection's screening of travelers entering the United States, besides 
conducting work at the agency's headquarters in Washington, D.C., we 
visited various land and air ports of entry in four states--California, 
Michigan, New York, and Texas (see table 2). We judgmentally selected 
these four states because each has major land and air ports of entry. 
Also, the four states are geographically dispersed and collectively 
have ports of entry on both the northern and southern borders of the 
United States.

Table 2: U.S. Customs and Border Protection Ports of Entry Visited by 
GAO:

State: California; Land ports of entry: San Ysidro; Air ports of entry: 
Los Angeles International Airport.

State: Michigan; Land ports of entry: Detroit Port Huron; Air ports of 
entry: Detroit Metropolitan Airport.

State: New York; Land ports of entry: Niagara Falls; Air ports of 
entry: John F. Kennedy International Airport.

State: Texas; Land ports of entry: Laredo; Air ports of entry: Dallas/ 
Fort Worth International Airport.

[End of table]

Regarding the State Department, we focused on screening of applicants 
for nonimmigrant visas.[Footnote 48] We performed our work at State 
Department headquarters in Washington, D.C, and did not visit consular 
offices abroad.

More details about the scope and methodology of our work regarding each 
of the objectives are presented in the following sections, respectively.

Extent That the Numbers of Terrorist Watch List Misidentifications Are 
Known, and Generally, How Misidentified Persons Could Be Affected:

From the Terrorist Screening Center, we obtained statistical 
information on misidentifications covering a 26-month time period-- 
December 2003 (when the center began operations) to January 2006. These 
statistics are based on screening encounters that were referred for 
identity verification to the center by the frontline-screening 
agencies, particularly U.S. Customs and Border Protection, which 
conducts screening at ports of entry, and the Transportation Security 
Administration, which provides guidance to air carriers, receives 
encounter inquiries from them, and makes applicable referrals to the 
center. Frontline-screening agencies are able to resolve some 
misidentifications on their own without having to refer them to the 
center. Similarly, in following federal guidance, airlines may also 
resolve some misidentifications without involving the Transportation 
Security Administration or necessitating subsequent referrals to the 
Terrorist Screening Center. However, the agencies and airlines 
generally do not maintain readily available statistics on how often 
they do so. Thus, we were unable to quantify the universe of terrorist 
watch-list-related misidentifications. However, to provide a contextual 
perspective, we obtained national statistics on the numbers of persons 
who were subject to terrorist watch list screening procedures 
conducted, for example, in fiscal year 2005 at ports of entry.

To determine how misidentified persons could be affected, we 
interviewed officials at the principal frontline-screening agencies-- 
the Transportation Security Administration, U.S. Customs and Border 
Protection, and the Department of State--whose missions most frequently 
and directly involve interactions with travelers. Also, as indicated in 
table 2, we made on-site observations of U.S. Customs and Border 
Protection screening operations at various ports of entry in 
California, Michigan, New York, and Texas. Our observations at these 
locations helped us better understand how the name-match screening 
process can affect misidentified persons, but these observations are 
not projectable to other locations.

To obtain additional information on ways that misidentified individuals 
could be affected by terrorist-watch-list-related screening, we asked 
the Transportation Security Administration and U.S. Customs and Border 
Protection to provide us examples of actual complaint letters to review:

* The Transportation Security Administration provided us a selection of 
24 terrorist watch-list-related complaint letters that the agency 
received during December 1, 2003 (when the Terrorist Screening Center 
became operational) to April 20, 2006. The agency attempted to select 
letters from different weeks throughout this time period; however, 
because a statistically projectable methodology was not used for the 
selections, the 24 letters are not representative of all complaints or 
inquiries (an unspecified total) that the Transportation Security 
Administration received during this time period.

* U.S. Customs and Border Protection's National Targeting Center 
provided us a selection of complaint letters submitted by 28 
individuals. The dates of the 28 complaint letters encompassed an 11- 
month period, ranging from June 2005 to April 2006. The 28 letters were 
not selected based on a statistically projectable methodology. Thus, 
the 28 letters are not representative of all complaints or inquiries-- 
regarding watch-list-related secondary screening at ports of entry-- 
that U.S. Customs and Border Protection's Customer Satisfaction Unit 
received during the 11-month time period and forwarded for research to 
the agency's National Targeting Center.[Footnote 49]

The scope of our work did not include contacting or interviewing any of 
the individuals who submitted complaint letters to the Transportation 
Security Administration or U.S. Customs and Border Protection.

To further identify ways that misidentified persons could be affected 
by watch-list-related screening, we contacted various associations that 
represent air carriers, travel agencies, and business travelers. 
Specifically, we contacted (1) the Air Transport Association, a trade 
organization of the principal U.S. airlines; (2) the American Society 
of Travel Agents; and (3) the National Business Travel Association, 
which represents corporate travel management professionals and the 
travel industry.

Also, we reviewed the results of a survey that the National Business 
Travel Association conducted in June 2006. According to its Web site 
(www.nbta.org), the association represents over 2,500 corporate travel 
managers and travel service providers who collectively manage and 
direct more than $170 billion of expenditures within the business 
travel industry, primarily for Fortune 1,000 companies. In June 2006, 
the association conducted a survey of 1,316 corporate travel managers; 
the survey posed a range of questions that addressed how terrorist 
watch list screening by the Transportation Security Administration and 
air carriers affected travelers. A total of 444 corporate travel 
managers responded to the survey. The responses may not be 
representative of all of the association's corporate travel managers.

Major Reasons That Misidentifications Occur, and Actions the Terrorist 
Screening Center and Frontline-Screening Agencies Are Taking to Reduce 
the Number of Misidentified Persons or Expedite Them through the 
Screening Process:

Major Reasons That Misidentifications Occur:

Regarding why misidentifications occur, our work focused on 
interviewing officials at and reviewing documentation obtained from the 
Terrorist Screening Center and three frontline-screening agencies--the 
Transportation Security Administration, U.S. Customs and Border 
Protection, and the Department of State. We also interviewed security 
officers at five major domestic air carriers about their role in name- 
match screening against the No Fly and Selectee lists and obtained 
their views on the causes of misidentifications. Further, we reviewed 
the work of two groups regarding factors they have identified that 
contribute to misidentifications--the Terrorist Screening Center's 
Search Engine Standardization Working Group[Footnote 50] and the 
Department of Homeland Security's Data Privacy and Integrity Advisory 
Committee.[Footnote 51]

Actions to Reduce the Number of Misidentified Persons or Expedite Them 
through the Screening Process:

At the Terrorist Screening Center, we interviewed the director, 
principal deputy director, chief information officer, and other senior 
managers and staff regarding data-quality initiatives, including 
efforts to identify and correct troublesome records related to 
misidentifications. Additionally, we inquired about the status of the 
center's efforts to implement recommendations made by the Department of 
Justice's Office of the Inspector General in its June 2005 
report.[Footnote 52] Among other things, the Inspector General 
recommended that the Terrorist Screening Center develop procedures to 
regularly review and test the information contained in the consolidated 
terrorist watch list to ensure that the data are complete, accurate, 
and nonduplicative.

At the three frontline-screening agencies, we interviewed applicable 
program managers regarding initiatives being taken to expedite 
frequently misidentified persons through the screening process. We 
inquired particularly about any computer-based initiatives that use 
applicable databases to help ensure that travelers who have been 
frequently misidentified in the past are no longer subjected to 
intensive screening, unless warranted by new data.

In further reference to potential initiatives for minimizing 
misidentifications as well as better confirming the identities of 
terrorists, we reviewed the Terrorist Screening Center's strategic plan 
and discussed with center officials the outlook for using biometric 
data--such as fingerprints--to supplement name-based screening. 
Similarly, in our interviews with officials of the frontline-screening 
agencies, we discussed programs that currently use biometric data, such 
as the U.S. Visitor and Immigrant Status Indicator Technology (US- 
VISIT) program, which is an entry-exit tracking system designed to 
collect, maintain, and share information on selected foreign nationals 
who travel to the United States.

Redress Opportunities Established by the Terrorist Screening Center and 
Frontline-Screening Agencies to Address Concerns from Misidentified and 
Mistakenly Listed Persons:

As used in this report, the term "redress" generally refers to an 
agency's complaint-resolution process, whereby individuals may seek 
resolution of their concerns about an agency action. We identified 
elements of the opportunities for redress offered by the Terrorist 
Screening Center and the three frontline-screening agencies, and we 
generally analyzed their respective policies and procedures. However, 
we did not address the relation between agency redress and other 
possible remedies, such as judicial review, which involves invoking the 
legal system through a civil action. Rather, the scope of our work 
focused on means for redress made available by agencies for 
inconvenienced persons.

We reviewed the Terrorist Screening Center's standard operating 
procedures for redress and interviewed the center official (privacy 
officer) principally responsible for watch-list-related redress. Also, 
we obtained and reviewed statistics and general disposition or outcome 
information regarding redress queries that the center received and 
processed to completion in calendar year 2005.[Footnote 53]

Further, at the three frontline-screening agencies, we reviewed redress-
related documentation, including standard operating procedures and 
training materials, and we interviewed the officials responsible for 
redress. Specifically, we interviewed the Director of the 
Transportation Security Administration's Office of Transportation 
Security Redress, the head of U.S. Customs and Border Protection's 
Customer Satisfaction Unit, and program managers at the State 
Department's Bureau of Consular Affairs responsible for processing 
nonimmigrant visa applications.

Also, to generally determine what watch-list-related redress 
information was publicly available, we reviewed the Federal Bureau of 
Investigation's Web site for the Terrorist Screening Center. In turn, 
from that overview Web site (see app. II), we followed up on any online 
links or references to the redress processes of the Transportation 
Security Administration (see app. III), U.S. Customs and Border 
Protection (see app. IV), and the State Department.

In addition, we contacted the Department of Justice's Office of Legal 
Policy, which has a lead role in ongoing efforts to develop an 
interagency memorandum of understanding to help ensure that redress 
processes are formally documented, with clearly established 
responsibilities for the Terrorist Screening Center and all interagency 
partners. Also, we contacted the executive director of the Privacy and 
Civil Liberties Oversight Board to discuss its role in facilitating 
development of the interagency memorandum of understanding.[Footnote 
54] However, because the memorandum of understanding was in draft form 
at the time of our study, we have not had an opportunity to review it.

Data Reliability:

In addressing our objectives, we obtained the following statistics from 
the Terrorist Screening Center:

* The number of watch-list-related screening encounters referred to the 
center by frontline-screening agencies during the period December 2003 
to January 2006.

* The number and general dispositions of redress queries that the 
center received and processed to completion in calendar year 2005.

We discussed the sources of the data with Terrorist Screening Center 
officials, including the chief information officer, and we reviewed 
documentation regarding the compilation of the statistics. We 
determined that the statistics were sufficiently reliable for the 
purposes of presenting overall patterns and trends.

Appendix II: Terrorist Screening Center: Terrorist-Watch-List Redress 
Process:

This appendix, which consists of two sections, presents publicly 
available information that we copied from the Web site of the Federal 
Bureau of Investigation:

* The first section of the appendix is an overview of the Terrorist 
Screening Center's watch-list-related redress process and also presents 
contact information for three frontline-screening agencies--the 
Transportation Security Administration, U.S. Customs and Border 
Protection, and the Department of State.

* The second section covers frequently asked questions.

Overview and Contact Information [Copied from the FBI's Web site, 
http://www.fbi.gov. Accessed August 2006.]

"The Terrorist Screening Center cannot confirm or deny whether an 
individual is on the consolidated terrorist watch list, because this 
information is derived from classified and sensitive law enforcement 
and intelligence. The nondisclosure of the contents of the watch list 
protects the operational counterterrorism and intelligence collection 
objectives of the government, as well as the personal safety of those 
involved in counterterrorism investigations. The watch list remains an 
effective tool in the government's counterterrorism efforts because its 
contents are not disclosed.

"The Terrorist Screening Center works with other agencies on a daily 
basis to resolve complaints from individuals who are experiencing 
repeated delays or difficulties during a screening process that may be 
related to the terrorist watch list. Because individuals may experience 
problems during screening for any number of reasons, and not just 
because of the terrorist watch list, individuals should contact the 
agency that is conducting the screening process in question. The 
screening agency is in the best position to resolve issues.

"Contact information:

"The Terrorist Screening Center does not accept redress inquiries 
directly from the public. Members of the public should contact the 
relevant screening agency with complaints about a negative screening 
experience.

"Please direct the public to contact the following screening agencies 
to submit a complaint about a negative screening experience.

"Frequently Asked Questions" 
[Copied from the FBI's Web site, www.fbi.gov. Accessed August 2006.]

"Why was the Terrorist Screening Database created?

Prior to the creation of the terrorist-screening database, information 
about known or suspected terrorists was dispersed throughout the U.S. 
government and no one agency was charged with consolidating it and 
making it available for use in terrorist screening. Under Homeland 
Security Presidential Directive-6, the Terrorist Screening Center now 
provides "one-stop shopping" so that every government screener is using 
the same terrorist watch list--whether it is an airport screener, an 
embassy official issuing visas overseas, or a state or local law 
enforcement officer on the street. The Terrorist Screening Center 
allows government agencies to run name checks against the same 
comprehensive list with the most accurate, up-to-date information about 
known and suspected terrorists.

Who gets included in the terrorist-screening database?

Per Homeland Security Presidential Directive-6, only individuals who 
are known or appropriately suspected to be or have been engaged in 
conduct constituting, in preparation for, in aid of, or related to 
terrorism are included in the terrorist-screening database.

Does the terrorist screening database contain information on domestic 
terrorists, like Timothy McVeigh?

Yes. The terrorist-screening database contains information on both 
international and domestic terrorists.

Does the terrorist-screening database contain information on people who 
have been convicted of a crime?

The purpose of the terrorist-screening database is not to hold 
information on individuals who have been convicted of a crime; however, 
an individual appropriately included in the terrorist-screening 
database may also have a criminal history. None of the information 
pertaining to the criminal history is contained or referenced in the 
terrorist-screening database.

Are there U.S. citizens in the terrorist-screening database?

Yes, U.S. citizens are included in terrorist-screening database if they 
meet the Homeland Security Presidential Directive-6 terrorism nexus 
criteria.

Can I find out if I am in the terrorism screening database?

The Terrorist Screening Center cannot reveal whether a particular 
person is in the terrorist-screening database. The terrorist-screening 
database remains an effective tool in the government's counterterrorism 
efforts because its contents are not disclosed. If the Terrorist 
Screening Center revealed who was in the terrorist-screening database, 
terrorist organizations would be able to circumvent the purpose of the 
terrorist watch list by determining in advance which of their members 
are likely to be questioned or detained.

I am having trouble when I try to fly or cross the border into the 
United States. Does this mean I am in the terrorist-screening database?

No. At security checkpoints like our nation's borders, there are many 
law enforcement or security reasons that an individual may be singled 
out for additional screening. Most agencies have redress offices (e.g., 
Ombudsman) where individuals who are experiencing repeated problems can 
seek help. If an individual is experiencing these kinds of 
difficulties, he/she should cooperate with the agency screeners and 
explain the recurring problems. The screeners can supply instructions 
on how to raise concerns to the appropriate agency redress office.

I have been told that I am on a terrorist watch list by an airline 
employee and I frequently have difficulty when I fly. Does this mean I 
am in the terrorist-screening database?

No; however, an individual may be a "misidentified person." A 
misidentified person is someone who is experiencing a delay during 
screening because they have a similar name to a person in the terrorist-
screening database. Misidentified persons are sometimes delayed while 
the government works to distinguish them from the terrorist in the 
terrorist-screening database. Because these delays are frustrating and 
inconvenient, there are several initiatives in progress to help 
streamline the clearance process for misidentified persons. If an 
individual believes he/she is having a misidentification problem, 
he/she should contact the screening agency's redress office for 
assistance.

Are individuals removed from the terrorist-screening database?

Yes. The Terrorist Screening Center works with partner agencies through 
a formal process to remove individuals who no longer meet the Homeland 
Security Presidential Directive-6 terrorism criteria.

How does the Terrorist Screening Center ensure that the terrorist- 
screening database is accurate?

The Terrorist Screening Center has a staff dedicated to redress and 
quality assurance that conducts comprehensive as well as case-specific 
reviews of terrorist-screening database records to ensure they are 
current, accurate, and thorough. The Terrorist Screening Center 
conducts research and coordinates with other federal agencies to ensure 
the terrorist record is as complete, accurate, and thorough as 
possible. The Terrorist Screening Center's redress and quality 
assurance process has resulted in the correction or removal of hundreds 
of records in the terrorist-screening database.

What are the Terrorist Screening Center's redress procedures?

See the TSC Redress Procedures webpage for details. [GAO note: The 
procedures are copied in the first section of this appendix.]

Does the Transportation Security Administration's Secure Flight program 
have anything to do with the terrorist-screening database?

Secure Flight is a congressionally mandated program that will check the 
names and dates of birth of passengers on domestic flights against the 
terrorist-screening database. As with all government programs that 
screen for terrorists, the Terrorist Screening Center provides this 
program support to ensure that terrorist identity matches are correct.

What prevents the Terrorist Screening Center from violating the civil 
liberties of Americans?

The Terrorist Screening Center only receives information collected by 
other government entities with pre-existing authority to do so. Each 
agency that contributes data to the Terrorist Screening Center must 
comply with legislation, as well as its own policies and procedures to 
protect privacy rights and civil liberties. The handling and use of 
information, including information about U.S. citizens and legal 
immigrants, is governed by the same statutory, regulatory, and 
constitutional requirements as if the information was not to be 
included in a Terrorist Screening Center managed database."

[End of section]

Appendix III: Transportation Security Administration: Traveler Identity 
Verification Program:

This appendix presents an overview of the Transportation Security 
Administration's (TSA) traveler identify verification program for air 
passengers who are affected by terrorist watch list screening. An 
individual can voluntarily provide TSA with additional personal- 
identifying information, which the agency will use to decide whether 
the person's name should be put on a cleared list--that is, a list that 
contains the names and other personal-identifying information of 
individuals who have been checked and cleared as being persons not on 
the No Fly and Selectee lists. Airlines are to use the cleared list to 
more quickly determine that these passengers are not the persons whose 
names are on the No Fly and Selectee lists. As needed, TSA provides the 
airlines with updates of the No Fly and Selectee lists and the cleared 
list.

Specific information about TSA's traveler identity verification program 
is publicly available on the agency's Web site (www.tsa.gov). The 
following sections of this appendix reproduce--as exhibits A and B-- 
relevant information from TSA's Web site (accessed August 2006):

* Exhibit A: Our Traveler Identity Verification Program.

* Exhibit B: Traveler Identity Verification (TSA Form 2301, May 2006).

Generally, to participate in the program, an individual must complete a 
traveler identity verification form and return the form and copies of 
specified identity documents to TSA.

Exhibit A: "Our Traveler Identity Verification Program"

"Told that you are on a Federal Government Watch List?

Problems printing your boarding pass at the kiosk or from home?

Experience other delays while checking-in for flights?

Our Office of Transportation Security Redress is here to help with our 
new Traveler Identity Verification Program.

Why am I having these problems?

TSA and the airlines are required to check and confirm that you are 
properly identified prior to your flight for safety and security. You 
may experience inconveniences when you present your identification 
during check-in due to mistaken identity or incorrect information. Our 
Traveler Identity Verification Program works with the relevant parties 
(including airlines) to resolve any inaccuracies or inconsistencies 
that may have resulted in misidentifications.

Am I on the No-Fly List?!:

If you receive a boarding pass, you are not on the No-Fly List. Most 
commonly, passengers who are told that they are on the No-Fly List 
have, in fact, a similar name to an individual on the Watch Lists.

What do I need to do?

You are invited to participate in the TSA Traveler Identity 
Verification Program by completing and returning the following 
information to TSA:

* Traveler Identity Verification Form (WORD 145 KB):

* A copy of your U.S. passport OR:

* Copies of three of the following:

* Driver's License:

* Birth Certificate:

* Voter Registration:

* Military ID Card:

* Visa:

* Naturalization Card:

* Government ID Card:

How does TSA review my information?

Your submission is reviewed to determine if the delays are caused by 
mistaken identity or incorrect information. TSA will respond to you in 
writing and provide air carriers with your identifying information to 
help properly identify you at check-in and expedite your future travel.

I participated in the Traveler Identity Verification Program, but I'm 
still experiencing problems.

Airline check-in procedures must still be followed. We currently 
distribute the Watch Lists to the airlines, who compare your 
reservation information to the Watch Lists prior to your flight. The 
airlines use varying procedures and technology to conduct this 
comparison, which could inadvertently lead to continued delays.

We are developing a program called Secure Flight to enhance the 
security of air travel in the U.S. while reducing security-related 
delays for the traveling public. It will allow the federal government, 
instead of individual airlines, to compare passenger data against the 
Watch Lists prior to check-in at the airport, while fully protecting 
privacy and civil liberties.

Our goal going forward is to ensure travelers' security with minimal 
disruptions.

Please note that you will be subject to screening procedures at the 
checkpoint. Every passenger will still walk through a metal detector, 
their carry-on bags will still be X-rayed, and every checked bag will 
still be screened for explosives. Additionally, you may be randomly 
selected at the airline counter or upon arrival at the checkpoint for 
secondary screening.

We will continue to work with travelers to minimize any unnecessary 
delays. We will continue to look at process and technology improvements 
to ensure a safe and efficient travel experience."

Appendix IV: U.S. Customs and Border Protection: Online Information:

Background and Preliminary Observation:

Appendix II provides an overview of the redress process used by the 
Terrorist Screening Center for addressing complaints or concerns 
resulting from the use of terrorist watch lists to screen individuals. 
As stated in appendix II, the Terrorist Screening Center is to work 
with frontline-screening agencies to resolve complaints from 
individuals who are experiencing repeated delays or difficulties during 
a screening process that may be related to a terrorist watch list. For 
instance, the Terrorist Screening Center's overview guidance notes that 
complainants experiencing such problems at U.S. borders and ports of 
entry should contact U.S. Customs and Border Protection. In further 
reference to the redress process for misidentifications of these 
individuals, the overview guidance provides an online link to the U.S. 
Customs and Border Protection's Interagency Border Inspection System 
Fact Sheet (reproduced below). The fact sheet does not specifically 
mention terrorist watch lists and the redress process.

However, U.S. Customs and Border Protection's Web site (www.cbp.gov), 
which can be directly accessed by the public, does provide information 
regarding the agency's Customer Satisfaction Unit and how complaints 
are handled as well as information on trusted-traveler programs.

Interagency Border Inspection System Fact Sheet:

GAO note: The fact sheet consists solely of the following six questions 
and answers, which we copied from the Web site of U.S. Customs and 
Border Protection (accessed August 2006).

"What Is IBIS?"

"IBIS is the acronym for the Interagency Border Inspection System."

"Who Uses IBIS?"

"In addition to U.S. Customs and Border Protection, law enforcement and 
regulatory personnel from 20 other federal agencies or bureaus use 
IBIS. Some of these agencies are the Federal Bureau of Investigation; 
U.S. National Central Bureau of the International Criminal Police 
Organization; the Drug Enforcement Administration; the Bureau of 
Alcohol, Tobacco, Firearms and Explosives; the Internal Revenue 
Service; the Coast Guard; the Federal Aviation Administration; the 
Secret Service; and the Animal and Plant Health Inspection Service, 
just to name a few. Also, information from IBIS is shared with the 
Department of State for use by Consular Officers at U.S. Embassies and 
Consulates."

"What Does IBIS Provide?"

"IBIS assists the majority of the traveling public with the expeditious 
clearance at ports of entry while allowing the border enforcement 
agencies to focus their limited resources on those potential non- 
compliant travelers. IBIS provides the law enforcement community with 
access to computer-based enforcement files of common interest. It also 
provides access to the FBI's National Crime Information Center and 
allows its users to interface with all fifty states via the National 
Law Enforcement Telecommunications Systems."

"Where Is IBIS?"

"IBIS resides on the Treasury Enforcement Communications System at the 
U.S. Customs and Border Protection's Data Center. Field level access is 
provided by an IBIS network with more than 24,000 computer terminals. 
These terminals are located at air, land, and sea ports of entry."

"What Information Is in IBIS?"

"IBIS keeps track of information on suspect individuals, businesses, 
vehicles, aircraft, and vessels. IBIS terminals can also be used to 
access National Crime Information Center records on wanted persons, 
stolen vehicles, vessels or firearms, license information, criminal 
histories, and previous Federal inspections. The information is used to 
assist law enforcement and regulatory personnel."

"Additional Questions?"

"Any concerns you may have as an international traveler or importer 
about the use or application of IBIS may be addressed to:

U.S. Customs and Border Protection Freedom of Information Act/ Customer 
Satisfaction Unit Room 5.5 C 1300 Pennsylvania Avenue, N.W. Washington,

Ms. Eileen Larence: 
Director:

Office 441 G Street, NW:
Washington, DC 20548:

Dear Ms. Larence:

Thank you for the opportunity to review and comment on the Government 
Accountability Office's (GAO's) draft report entitled, TERRORIST WATCH 
LIST SCREENING: Efforts to Help Reduce Adverse Effects on the Public 
(GAO-06-1031). Technical comments have been provided under separate 
cover.

The Department of Homeland Security appreciates your report and 
findings as well as your recognition of the many efforts we are 
currently undertaking to enhance terrorist screening and our redress 
efforts.

We do have one suggestion for an additional paragraph in your report, 
perhaps in your Results in Brief and Concluding Observations sections.

The Department of Homeland Security is working with the Departments of 
Justice, State and others on a larger set of travel screening redress 
issues, which the interagency memorandum of understanding, with its 
focus on redress related to the terrorist watch lists, will supplement. 
On January 17, 2006, the Departments of State and Homeland Security 
announced an initiative on "Secure Borders and Open Doors in the 
Information Age," otherwise known as the Rice-Chertoff Initiative. Part 
Three, "Smarter Screening," includes a "'One Stop' Redress for 
Travelers." The purpose is to establish a government-wide redress 
process to address perceived problems in international and domestic 
traveler prescreening. Secretary Chertoff made it a goal to establish 
this process by the end of the calendar year so that those with 
complaints or legitimate issues can resolve them with greater 
efficiency. US-VISIT and the Office for Civil Rights and Civil 
Liberties (CRCL) within DHS have been tasked with initiating from 
within the relevant DHS components and the Department of State a 
governance board and working group for this project. The new director 
of DHS's Screening Coordination Office now chairs the governance board 
with CRCL and US-VISIT as co-chairs. Representatives from State, the 
Terrorist Screening Center, and DHS's U.S. Customs and Border 
Protection, Transportation Security Administration, U.S. Immigration 
and Customs Enforcement, US-VISIT, CRCL and Office of Policy are all 
involved with the working group.

Thank you again for the opportunity to comment on this draft report and 
we look forward to working with you on future homeland security issues.

Sincerely,

[Signed by]

Adverse Effects on the Public: 
(GAO-06-1031, GAO Code 440374):

Thank you for allowing the Department of State the opportunity to 
comment on the draft report Terrorist Watch List Screening: Efforts to 
Help Reduce Adverse Effects on the Public.

The report accurately describes the visa process and the Department of 
State's position that the administrative processing time required to 
screen a visa applicant, including, if required, the processing of a 
Security Advisory Opinion (SAO) review, is a necessary part of the visa 
application procedure rather than an adverse governmental action. The 
report also acknowledges the Department's interest in data integrity 
and taking steps to minimize the impact of the SAO process on the 
traveling public. (Note: the SAO process is the means through which 
Department of State Consular Officers screen visa applicants against 
the Terrorist Watch List.)

The Department has the following comments:

1. The GAO notes, first on the page immediately following the report 
cover sheet and several times throughout the document, that of the tens 
of thousands of names sent to the Terrorist Screening Center (TSC) by 
the frontline screening agencies, about half were "misidentifications." 
From the perspective of the State Department, which uses the Terrorist 
Watch List primarily as a screening tool for visa adjudication, a 
"misidentification" is not an adverse result for the visa applicant. 
Rather, a negative response would clear a visa applicant of an 
association with a terrorist identity (though subject to a second 
review upon seeking admission at a U.S. port of entry.)

2. The description of the Department's visa name check process in the 
body of the report is accurate. However, the general overview 
description and chart on pages 11-13 are not accurate as descriptions 
of the visa SAO process. The description and chart state that 
"inconclusive .. uncertain and other hard-to-verify potential 
matches.." are to be referred to the applicable screening agency. If 
that agency is unable to conclusively determine whether a hit is an 
exact match, then it contacts the Terrorist:

Screening Center. In describing visa operations, it is more accurate to 
say (and depict on a chart) that consular officers are required to 
submit to the Department for a Security Advisory Opinion all hits that 
cannot positively be labeled a mismatch. That SAO request is 
automatically routed to the TSC and other screening agencies, and the 
Department will not recommend a course of action to a post until the 
TSC and other screening agencies have advised us that either the hit is 
a mismatch, or that derogatory information exists and must be reviewed 
to determine whether a legal basis for a visa denial exists.

FOOTNOTES

[1] According to the Transportation Security Administration, persons on 
the No Fly list should be precluded from boarding an aircraft bound 
for, or departing from, the United States. In contrast, being on the 
Selectee list does not mean that the individual will be precluded from 
boarding a plane or entering the United States. Instead, any person on 
the Selectee list is to receive additional screening, which may involve 
a physical inspection of the person and a hand-search of luggage. 

[2] The term "misidentification" refers to a person initially matched 
by a screening agency to a name on the watch list, but upon closer 
examination, the person is found to not match any watch list record. 

[3] As used in this report, the term "redress" generally refers to an 
agency's complaint-resolution process, whereby individuals may seek 
resolution of their concerns about an agency action. In the report, we 
describe elements of the opportunities for redress offered by several 
agencies, and we generally analyze their respective policies and 
procedures. However, we do not address the relation between agency 
redress and other possible remedies, such as judicial review. 

[4] For purposes of this report, the term "mistakenly listed persons" 
includes two categories of individuals--(1) persons who never should 
have been included on the watch list but were due to some type of error 
and (2) persons who were appropriately included on the watch list at 
one time but no longer warrant inclusion on the terrorist watch list 
due to subsequent events. 

[5] Although the terrorist watch list is used for a variety of 
screening purposes, such as conducting background checks of workers who 
have access to secure areas of the national transportation system, our 
work generally focused on the screening of travelers. At the 
Transportation Security Administration, we examined the screening of 
air passengers prior to their boarding a flight; at U.S. Customs and 
Border Protection, we examined the screening of travelers entering the 
United States through ports of entry; and at the Department of State, 
we examined the screening of nonimmigrant visa applicants. 

[6] According to the FBI, the specific number of potential matches sent 
to the Terrorist Screening Center that turned out to be 
misidentifications is sensitive information; however, the total is 
substantially less than 100,000. 

[7] An algorithm is a prescribed set of well-defined, unambiguous rules 
or processes for the solution of a problem in a finite number of steps. 
Pursuant to Transportation Security Administration security directives 
and implementing guidance, airlines are to prescreen passengers by 
matching their names against the No Fly and Selectee lists. 

[8] Any such concern or complaint raised formally by an affected 
individual is what the Terrorist Screening Center calls a redress 
query. Specifically, the Terrorist Screening Center defines a "redress 
query" as communication from individuals or their representatives 
inquiring or complaining about an adverse experience during a terrorist 
watch-list-related-screening process conducted or sponsored by a 
federal agency, including congressional inquiries to federal agencies 
on behalf of their constituents.

[9] GAO, Information Technology: Terrorist Watch Lists Should Be 
Consolidated to Promote Better Integration and Sharing, GAO-03-322 
(Washington, D.C.: Apr. 15, 2003). 

[10] The Transportation Security Administration is developing a new 
passenger prescreening program, known as Secure Flight. Under the 
Secure Flight program, the agency plans to take over, from commercial 
airlines, the responsibility to compare identifying information on 
airline passengers against information on known or suspected 
terrorists. The agency expects that Secure Flight will improve 
passenger prescreening as compared with the current airline-operated 
process. In June 2006, we reported that the Transportation Security 
Administration still faces significant challenges in developing and 
implementing the Secure Flight program. See, GAO, Aviation Security: 
Management Challenges Remain for the Transportation Security 
Administration's Secure Flight Program, GAO-06-864T (Washington, D.C.: 
June 14, 2006). 

[11] Also, the FBI and designated state and local criminal justice 
agencies access the Violent Gang and Terrorist Organization File in 
conducting background checks on individuals seeking to purchase 
firearms or obtain permits to possess, acquire, or carry firearms. See 
GAO, Gun Control and Terrorism: FBI Could Better Manage Firearm-Related 
Background Checks Involving Terrorist Watch List Records, GAO-05-127 
(Washington, D.C.: Jan. 19, 2005). 

[12] Airlines are to contact the Transportation Security 
Administration, which may then contact the Terrorist Screening Center, 
as necessary. 

[13] In commenting on a draft of this report, the State Department 
noted that the general overview presented in figure 1 is not fully 
reflective of the process for screening nonimmigrant visa applicants 
against the terrorist watch list. Specifically, the department 
emphasized that for any hit that clearly is not a mismatch, consular 
officers are required to obtain a security advisory opinion. That is, 
the consular post must ask Department of State headquarters to initiate 
a process of requesting that the Terrorist Screening Center and other 
relevant agencies check their respective databases or systems for the 
existence of any investigative or intelligence information regarding 
the individual and pass the results back to the department for use in 
recommending a course of action to the post.

[14] Since the late 1990s, airline passenger prescreening has been 
conducted using the Computer-Assisted Passenger Prescreening System 
(CAPPS I)--in which data related to a passenger's reservation and 
travel itinerary are compared against characteristics (known as CAPPS I 
rules) used to select passengers who require additional scrutiny--and 
through the matching of passenger names to terrorist watch lists. See, 
GAO, Aviation Security: Secure Flight Development and Testing Under 
Way, but Risks Should Be Managed as System Is Further Developed, GAO-05-
356 (Washington, D.C.: Mar. 28, 2005), which reported that 
approximately 99 percent of all passengers on domestic flights are 
screened under the air carrier-operated, automated CAPPS I system, and 
the remaining 1 percent of passengers are screened by air carriers who 
do not have an automated system. 

[15] The Transportation Security Administration provides security 
directives and implementing guidance to foreign and domestic aircraft 
operators for use in ensuring that individuals who pose a threat to 
civil aviation are denied boarding passes or are subjected to 
additional screening, as appropriate.

[16] Also, terrorist-watch-list-screening procedures are applicable to 
international flights--of foreign and domestic air carriers--into or 
from the United States. 

[17] A nonimmigrant is a person, not a citizen or national of the 
United States, seeking to enter the United States temporarily for a 
specific purpose, such as business or pleasure.

[18] As discussed in appendix I, the Transportation Security 
Administration provided us a selection of 24 terrorist watch-list- 
related complaint letters that the agency received from December 1, 
2003 (when the Terrorist Screening Center became operational) to April 
20, 2006. The agency attempted to select letters from different weeks 
throughout this time period; however, because a statistically 
projectable methodology was not used for the selections, the 24 letters 
are not representative of all complaints or inquiries (an unspecified 
total) that the Transportation Security Administration received during 
this time period.

[19] According to its Web site (www.nbta.org), the National Business 
Travel Association represents over 2,500 corporate travel managers and 
travel service providers who collectively manage and direct more than 
$170 billion of expenditures within the business travel industry, 
primarily for Fortune 1,000 companies. In June 2006, the association 
conducted a survey of 1,316 corporate travel managers, and 444 
responded to the survey. Of the responding travel managers, 107 
reported that they have employees who repeatedly have had to go to the 
airline ticket counter to obtain a boarding pass. (Accessed August 
2006.)

Civil Liberties--DHS Privacy Office Report Assessing the Impact of the 
Automatic Selectee and No Fly Lists on Privacy and Civil Liberties as 
Required under Section 4012(b) of the Intelligence Reform and Terrorism 
Prevention Act of 2004 (Washington, D.C.: Apr. 27, 2006). 

[21] As discussed in appendix I, besides conducting work at U.S. 
Customs and Border Protection headquarters in Washington, D.C., we 
visited various land and air ports of entry in four states--California, 
Michigan, New York, and Texas. We judgmentally selected these four 
states because each has major land and air ports of entry, and the 
states collectively have ports of entry on both the northern and 
southern borders of the United States. 

[22] As discussed in appendix I, U.S. Customs and Border Protection 
provided us a selection of complaint letters submitted by 28 
individuals. The dates of the 28 complaint letters encompassed an 11- 
month period, ranging from June 2005 to April 2006. The 28 letters were 
not selected based on a statistically projectable methodology. Thus, 
the 28 letters are not representative of the approximately 220 
complaints or inquiries--regarding watch-list-related secondary 
screening at ports of entry--that U.S. Customs and Border Protection's 
Customer Satisfaction Unit received during the 11-month time period and 
forwarded for research to the agency's National Targeting Center. 

[23] The extended or additional processing time is not always a one- 
time occurrence. In processing visa applications, consular posts may 
request security advisory opinions for a variety of reasons. Thus, even 
though an individual previously has been the subject of a security 
advisory opinion, a new visa application may present facts and 
circumstances that lead the consular post to request another security 
advisory opinion.

Security, State of New York, at a hearing before the Subcommittee on 
Crime, Terrorism, and Homeland Security, Committee on the Judiciary, 
and the Subcommittee on Intelligence and Counterterrorism of the Select 
Committee on Homeland Security, House of Representatives (Mar. 25, 
2004).

[25] The response to the state or local law enforcement officer may be 
provided by the Terrorist Screening Center or by the FBI's 
Counterterrorism Division (Terrorist Screening Operations Unit), as 
applicable.

departments of Homeland Security (including Transportation Security 
Administration and U.S. Customs and Border Protection), State, and 
Defense; FBI; and the intelligence community (including the National 
Counterterrorism Center, Central Intelligence Agency, National Security 
Agency, and Defense Intelligence Agency). Also, the National Institute 
of Standards and Technology acts as a special advisor to the working 
group.

the Terrorist Screening Center, Audit Report 05-27 (June 2005). 

[28] Although a purpose is to expedite frequently misidentified persons 
through the screening process, the database-annotation initiative is 
not a "redress" process as defined in this report. Under the 
initiative, the agency is taking action proactively rather than 
responding to specific complaints or redress queries submitted by 
individuals.

[29] In an earlier report, we assessed various biometric technologies. 
See, GAO, Technology Assessment: Using Biometrics for Border Security, 
GAO-03-174 (Washington, D.C.: Nov. 15, 2002). 

[30] In July 2005, the Secretary of Homeland Security announced that US-
VISIT would be enhanced to collect 10-finger scans.

Evaluation and Inspection Division, Follow-up Review of the FBI's 
Progress Toward Biometric Interoperability between IAFIS and IDENT 
(Washington, D.C.: July 2006). 

[32] The Transportation Security Administration is authorized to 
"establish requirements to implement trusted passenger programs and use 
available technologies to expedite security screening of passengers who 
participate in such programs, thereby allowing security screening 
personnel to focus on those passengers who should be subject to more 
extensive screening." See Pub. L. No. 107-71, § 109(a)(3), 115 Stat. 
597, 613 (2001).

[33] In the SENTRI program, for example, applicants must volunteer for 
(1) a biographical background check against criminal, law enforcement, 
customs, immigration, and terrorist databases; (2) a 10-fingerprint law 
enforcement check; and (3) a personal interview with a U.S. Customs and 
Border Protection officer.

[34] RFID is a wireless technology that stores and retrieves data 
remotely from devices. For instance, the technology allows information 
to be written to tags, which can be scanned or read from a distance. 
See, GAO, Information Security: Radio Frequency Identification 
Technology in the Federal Government, GAO-05-551 (Washington, D.C.: May 
27, 2005).

[35] Previously, the agency's Office of the Ombudsman handled all 
inquiries and complaints, including those regarding watch-list-related 
screening. 

[36] The Traveler Identity Verification Form (May 2006) replaced an 
earlier form, the Passenger Identity Verification Form. Regarding the 
latter, the Transportation Security Administration's instructions 
required the submission of notarized copies of three identification 
documents. Instructions for the new form do not require that the 
submitted documents be notarized.

[37] The cleared list procedure began in May 2003 under the agency's 
Office of the Ombudsman. 

[38] In March 2003, the Transportation Security Administration began 
developing CAPPS II, a second-generation computer-assisted passenger 
prescreening program, to provide improvements over CAPPS I and to 
screen all passengers flying into, out of, and within the United 
States. CAPPS II was to perform different analyses and access more 
diverse data, including data from government and commercial databases, 
to classify passengers according to their level of risk (i.e., 
acceptable risk, unknown risk, or unacceptable risk), which would in 
turn be used to determine the level of security screening each 
passenger would receive. Because of a variety of challenges, the 
Department of Homeland Security cancelled the development of CAPPS II 
in August 2004 and announced that a new prescreening program, called 
Secure Flight, would be developed.

§ 1101, et seq.) However, obtaining a visa from an American consul does 
not guarantee an alien's entry into the United States. Rather, a visa 
authorizes the alien to arrive at a port of entry, at which point a 
U.S. Customs and Border Protection officer will independently examine 
the alien's eligibility for admission. 

[41] See 8 U.S.C. § 1182(a). 

[42] Courts have long held that a consular officer's decision to grant 
or deny a visa is not subject to judicial review. See, e.g., Saavedra 
Bruno v. Albright, 197 F.3d 1153 (D.C. Cir. 1999); Centeno v. Schultz, 
817 F.2d 1212 (5th Cir. 1987); Li Hing of Hong Kong, Inc. v. Levin, 800

[45] The board was established by section 1061 of the Intelligence 
Reform and Terrorism Prevention Act of 2004. Pub. L. No. 108-458, 118 
Stat. 3638, 3684-88. The board advises the president and other senior 
executive branch officials as to whether privacy and civil liberties 
protections are appropriately considered in the development and 
implementation of laws, regulations, and executive branch policies 
related to efforts to protect the nation against terrorism. The five 
board members were sworn in and had their first meeting on March 15, 
2006. Additional information about the role of the board and its 
operations is available at www.privacyboard.gov.

[46] For purposes of this report, the term "misidentification" refers 
to a person initially matched by a screening agency to a name on the 
watch list, but upon closer examination, the person is found to not 
match any watch list record.

[47] As used in this report, the term "mistakenly listed persons" 
includes two categories of individuals--(1) persons who never should 
have been included on the watch list but were due to some type of error 
and (2) persons who were appropriately included on the watch list at 
one time but no longer warrant inclusion on the terrorist watch list 
due to subsequent events. 

[48] A nonimmigrant is a person, not a citizen or national of the 
United States, seeking to enter the United States temporarily for a 
specific purpose, such as business or pleasure.

[49] According to Customer Satisfaction Unit managers, all complaints 
regarding the terrorist watch list are forwarded to the agency's 
National Targeting Center, which has access to classified information 
that may be needed to determine if the incidents cited by complainants 
involved individuals who either are on the watch list or were 
misidentified. National Targeting Center managers told us that if 
research indicates that the substance of the complaint does involve 
watch-list-related screening conducted by U.S. Customs and Border 
Protection, the National Targeting Center will draft a response letter, 
which is to be signed by the Customer Satisfaction Unit and mailed to 
the individual. 

[50] The working group's membership includes representatives from the 
departments of Homeland Security (including Transportation Security 
Administration and U.S. Customs and Border Protection), State, and 
Defense; FBI; and the intelligence community (e.g., the National 
Counterterrorism Center, Central Intelligence Agency, National Security 
Agency, and Defense Intelligence Agency). Also, the National Institute 
of Standards and Technology acts as a special advisor to the working 
group.

[51] The charter of the committee is to advise the Secretary of 
Homeland Security and the Department of Homeland Security's chief 
privacy officer on programmatic, policy, operational, administrative, 
and technological issues within the department's areas of 
responsibility that affect individual privacy, data integrity, data 
interoperability, and other privacy-related matters.

the Terrorist Screening Center, Audit Report 05-27 (June 2005). 

[53] The Terrorist Screening Center defines a "redress query" as 
communication from individuals or their representatives inquiring or 
complaining about an adverse experience during a terrorist watch-list- 
related-screening process conducted or sponsored by a federal agency, 
including congressional inquiries to federal agencies on behalf of 
their constituents.

[54] The five-member board, which is part of the Executive Office of 
the President, was established by section 1061 of the Intelligence 
Reform and Terrorism Prevention Act of 2004. Pub. L. No. 108-458, 118 
Stat. 3638, 3684-88. The board advises the president and other senior 
executive branch officials as to whether privacy and civil liberties 
protections are appropriately considered in the development and 
implementation of laws, regulations, and executive branch policies 
related to efforts to protect the nation against terrorism. The five 
board members were sworn in and had their first meeting on March 15, 
2006. Additional information about the role of the board and its 
operations is available at www.privacyboard.gov.

[55] See appendix III. 

[56] On September 12, 2006, in providing technical comments on a draft 
of this report, U.S. Customs and Border Protection officials noted that 
the contact information given on the FBI's Web site should be as 
follows: U.S. Customs and Border Protection, Freedom of Information 
Act/Privacy Act Branch. Also, the comments noted that the telephone 
number should be removed. We suggested to the U.S. Customs and Border 
Protection officials that they coordinate with the FBI to ensure that 
appropriate contact information is available to the public.
