Why GAO Did This Study: 

This testimony summarizes GAO’s work on the Department of Homeland 
Security’s (DHS) efforts to implement the U.S. Visitor and Immigrant 
Status Indicator Technology (US-VISIT) program at air, sea, and land 
ports of entry (POE). US-VISIT is designed to collect, maintain, and 
share data on selected foreign nationals entering and exiting the 
United States at air, sea, and land POEs. These data, including 
biometric identifiers like digital fingerprints, are to be used to 
screen persons against watch lists, verify identities, and record 
arrival and departure. This testimony addresses DHS’s efforts to (1) 
implement US-VISIT entry capability, (2) implement US-VISIT exit 
capability, and (3) resolve longstanding management challenges that 
could impair DHS’s ability to effectively implement the US-VISIT 
program. GAO analyzed DHS and US-VISIT documents, interviewed program 
officials, and visited 21 land POEs with varied traffic levels on both 
borders. 

What GAO Found: 

DHS is operating US-VISIT entry capabilities at most POEs and has begun 
to work to move from 2 to10 fingerprint biometric capabilities and 
expand electronic information sharing with stakeholders. Of particular 
note is the fact that a US-VISIT biometric-based entry screening 
capability is operating at 115 airports, 14 seaports, and 154 land 
POEs. While US-VISIT has improved DHS’s ability to process visitors and 
verify identities upon entry, we found that management controls in 
place to identify and evaluate computer and other operational problems 
at land POEs were insufficient and inconsistently administered. 

Although US-VISIT has conducted various exit demonstration projects at 
a small number of POEs, a biometric exit capability is not currently 
available. According to program officials, this is due to a number of 
factors. For example, at this time the only proven technology available 
for biometric land exit verification would necessitate mirroring the 
processes currently in use for entry at these POEs, which would create 
costly staffing demands and infrastructure requirements, and introduce 
potential trade, commerce, and environmental impacts. Further, a pilot 
project to examine an alternative technology at land POEs did not 
produce a viable solution. By statute, DHS was to have reported to 
Congress by June 2005 on how it intended to fully implement a 
comprehensive, biometric entry/exit program, but DHS had not yet 
reported how it intended to do so, or use nonbiometric solutions. 

DHS continues to face longstanding US-VISIT management challenges and 
future uncertainties. For example, DHS had not articulated how US-VISIT 
is to strategically fit with other land border security initiatives and 
mandates and could not ensure that these programs work in harmony to 
meet mission goals and operate cost effectively. DHS had drafted a 
strategic plan defining an overall immigration and border management 
strategy but, as of February 2007, the plan was under review by OMB. 
Further, critical acquisition management processes need to be 
established and followed to ensure that program capabilities and 
expected mission outcomes are delivered on time and within budget. 
These processes include effective project planning, requirements 
management, contract tracking and oversight, test management, and 
financial management. Until these issues are addressed, the risk of US-
VISIT continuing to fall short of expectations is increased.

Mr. Chairman and Members of the Committee: 

I appreciate the opportunity to be here today to provide a summary of 
our work on the challenges facing the Department of Homeland Security 
(DHS) as it implements United States Visitor and Immigrant Status 
Indicator Technology (US-VISIT) at air, sea, and land ports of entry 
(POE).[Footnote 1] 

In the years since the 2001 terrorist attacks, the need to secure U.S. 
borders has taken on added importance and has received increasing 
attention from Congress and the public. In an effort to avoid 
repetition of such attacks, and improve overall national security, 
Congress and the Administration have sought better ways to record and 
track the entry and departure of foreign visitors who pass through U.S. 
POEs by air, land, or sea; to verify their identities; and to 
authenticate their travel documentation. Pursuant to several statutory 
mandates, DHS, in consultation with the Department of State, 
established an automated visitor system to integrate information on the 
entry and exit from the United States of foreign nationals, called the 
US-VISIT Program. According to DHS, the purpose of US-VISIT is to 
enhance the security of U.S. citizens and visitors, facilitate 
legitimate travel and trade, ensure the integrity of the U.S. 
immigration system, and protect visitors' privacy. The program is 
managed by the US-VISIT Program Office, which is headed by the US-VISIT 
Director, who currently reports to the DHS Deputy Secretary. However, 
as of March 31, 2007, the US-VISIT Program Office is expected to report 
to the newly established Under Secretary for the National Protection 
and Program Directorate. US-VISIT is used in the field by officers with 
U.S. Customs and Border Protection (CBP), a separate DHS component. 

US-VISIT is designed to use biographic information (e.g., name, 
nationality, and date of birth) and biometric information (e.g., 
digital fingerprint scans and photographs) to verify the identity of 
those covered by the program. The program applies to certain visitors 
whether they hold a nonimmigrant visa or are traveling from a country 
that has a visa waiver agreement with the United States under the Visa 
Waiver Program.[Footnote 2] U.S. citizens, lawful permanent residents, 
and most Canadian and Mexican[Footnote 3] citizens are currently exempt 
from being processed under US-VISIT upon entering and exiting the 
country.[Footnote 4] 

Many aspects of US-VISIT program implementation have been driven or 
defined by various legislative mandates. These include a 2001 statutory 
requirement to focus particularly on the use of biometric technology in 
developing the integrated entry-exit system subsequently named US- 
VISIT; a 2002 statutory requirement to develop biometric identifier 
standards to be used to verify the identity of persons seeking to enter 
the United States at POEs; and a requirement to install at all POEs 
equipment and software to allow biometric comparison and authentication 
of U.S. visas and other travel and entry documents issued to aliens, as 
well as Visa Waiver Program participant passports. In addition, by law, 
an integrated entry and exit data system was to be implemented at all 
U.S. POEs, including land POEs, by December 31, 2005, but there was no 
specific requirement to collect any new data on foreign nationals 
departing at land POEs by that date. The Intelligence Reform and 
Terrorism Prevention Act of 2004, on the other hand, did require the 
collection of biometric exit data for all individuals subject to US- 
VISIT, but it did not set a deadline for implementation of this 
requirement.[Footnote 5] 

My testimony today draws on this body of completed work to provide a 
snapshot of what US-VISIT capabilities have and have not been 
delivered, what work has recently begun to enhance already delivered 
capabilities, and the range of longstanding challenges that hamper DHS 
efforts to establish and live up to program expectations and 
commitments. All the work on which this testimony is based was 
performed in accordance with generally accepted government auditing 
standards. 

Summary: 

DHS is operating US-VISIT entry capabilities at most POEs and has begun 
to work to move from 2 to10 fingerprint biometric capabilities and 
expand electronic information sharing with stakeholders. Of particular 
note is the fact that a US-VISIT biometric-based entry screening 
capability is operating at 115 airports, 14 seaports, and 154 land 
POEs. While US-VISIT has improved DHS's ability to process visitors and 
verify identities upon entry, we found that management controls in 
place to identify and evaluate computer and other operational problems 
at land POEs were insufficient and inconsistently administered. 

Although US-VISIT has conducted various exit demonstration projects at 
a small number of POEs, a biometric exit capability is not currently 
available. According to program officials, this is due to a number of 
factors. For example, at this time the only proven technology available 
for biometric land exit verification would necessitate mirroring the 
processes currently in use for entry at these POEs, which would create 
costly staffing demands and infrastructure requirements, and introduce 
potential trade, commerce, and environmental impacts. Further, a pilot 
project to examine an alternative technology at land POEs did not 
produce a viable solution. By statute, DHS was to have reported to 
Congress by June 2005 on how it intended to fully implement a 
comprehensive, biometric entry/exit program, but DHS had not yet 
reported how it intended to do so, or use nonbiometric solutions. 

DHS continues to face longstanding US-VISIT management challenges and 
future uncertainties. For example, DHS had not articulated how US-VISIT 
is to strategically fit with other land border security initiatives and 
mandates and could not ensure that these programs work in harmony to 
meet mission goals and operate cost effectively. DHS had drafted a 
strategic plan defining an overall immigration and border management 
strategy but, in February 2007, we were told that the plan was with OMB 
and had not yet been approved. Further, critical acquisition management 
processes need to be established and followed to ensure that program 
capabilities and expected mission outcomes are delivered on time and 
within budget. These processes include effective project planning, 
requirements management, contract tracking and oversight, test 
management, and financial management. As we have reported for several 
years, DHS has yet to adequately do these things. Until these issues 
are addressed, the risk of US-VISIT continuing to fall short of 
expectations is increased. 

Background: 

US-VISIT is a large, complex governmentwide program intended to: 

* collect, maintain, and share information on certain foreign nationals 
who enter and exit the United States; 

* identify foreign nationals who (1) have overstayed or violated the 
terms of their visit; (2) can receive, extend, or adjust their 
immigration status; or (3) should be apprehended or detained by law 
enforcement officials; 

* detect fraudulent travel documents, verify visitor identity, and 
determine visitor admissibility through the use of biometrics (digital 
fingerprints and a digital photograph); and: 

* facilitate information sharing and coordination within the 
immigration and border management community. 

The US-VISIT Program Office has responsibility for managing the 
acquisition, deployment, operation, and sustainment of US-VISIT and has 
been delivering US-VISIT capability incrementally based, in part, on 
statutory deadlines for implementing specific portions of US-VISIT. For 
example, the statutory deadline for implementing US-VISIT at the 50 
busiest land POEs was December 31, 2004, and at the remaining POEs, 
December 31, 2005. From fiscal year 2003 through fiscal year 2007, 
total funding for the US-VISIT program has been about $1.7 billion. 
According to program officials, as of January 31, 2007, almost $1.3 
billion has been obligated to acquire, develop, deploy, enhance, 
operate, and maintain US-VISIT entry capabilities, and to test and 
evaluate exit capability options.[Footnote 6] 

Since 2003, DHS has planned to deliver US-VISIT capability in four 
increments: Increment 1 (air and sea entry and exit), Increment 2 (air, 
sea, and land entry and exit), Increment 3 (land entry), and Increment 
4, which is to define, design, build, and implement more strategic 
program capability, and which program officials stated will consist of 
a series of incremental releases or mission capability enhancements 
that will support business outcomes. In Increments 1 through 3, the 
program has built interfaces among existing ("legacy") systems, 
enhanced the capabilities of these systems, and deployed these 
capabilities to air, sea, and land POEs. The capabilities that DHS 
currently has regarding the first three increments have been largely 
acquired and implemented through existing system contracts and task 
orders. 

In reports on US-VISIT over the last several years, we have identified 
numerous challenges that DHS faces in delivering program capabilities 
and benefits on time and within budget. In September 2003, we reported 
that the US-VISIT program is a risky endeavor, both because of the type 
of program it is (large, complex, and potentially costly) and because 
of the way that it was being managed[Footnote 7]. We reported, for 
example, that the program's acquisition management process had not been 
established, and that US-VISIT lacked a governance structure. In March 
2004, we testified that DHS faces a major challenge maintaining border 
security while still welcoming visitors. Preventing the entry of 
persons who pose a threat to the United States cannot be guaranteed, 
and the missed entry of just one can have severe consequences. Also, US-
VISIT is to achieve the important law enforcement goal of identifying 
those who overstay or otherwise violate the terms of their visas. 
Complicating the achievement of these security and law enforcement 
goals are other key US-VISIT goals: facilitating trade and travel 
through POEs and providing for enforcement of U.S. privacy laws and 
regulation[Footnote 8]s. Subsequently, in May 2004, we reported that 
DHS had not employed the kind of rigorous and disciplined management 
controls typically associated with successful programs[Footnote 9]. 
Moreover, in February 2006, we reported that while DHS had taken steps 
to implement most of the recommendations from our 2003 and 2004 
reports, progress in critical areas had been s[Footnote 10]low. As of 
February 2006, of 18 recommendations we made since 2003, only 2 had 
been fully implemented, 11 had been partially implemented, and 5 were 
in the process of being implemented, although the extent to which they 
would be fully carried out is not yet known. In addition, in June 2006, 
we reported that US-VISIT contract and financial management needed to 
be strengthened; in December 2006, we reported that the US-VISIT 
program faced strategic, operational and technological challenges at 
land ports of entry; and in February 2007, we reported that planned 
expenditures for the US-VISIT program needed to be adequately defined 
and justified.[Footnote 11] 

US-VISIT Scope, Operations, and Processing at POEs: 

Currently, US-VISIT's scope includes the pre-entry, entry, status, and 
exit of hundreds of millions of foreign national travelers who enter 
and leave the United States at over 300 air, sea, and land POEs. Most 
land border crossers--including U.S. citizens, lawful permanent 
residents, and most Canadian and Mexican citizens--are, by regulation 
or statute, not required to enroll into US-VISIT.[Footnote 12] In 
fiscal year 2004, for example, U.S. citizens and lawful permanent 
residents constituted about 57 percent of land border crossers; 
Canadian and Mexican citizens constituted about 41 percent; and less 
than 2 percent were US-VISIT enrollees. Figure 1 shows the number and 
percentage of persons processed under US-VISIT as a percentage of all 
border crossings at land, air, and sea POEs in fiscal year 2004.

Border Crossings at Land, Air, and Sea Ports of Entry, Fiscal Year

Note: Persons processed by US-VISIT may include foreign nationals who 
were also issued an I-94 arrival/departure form (which shows the date 
of arrival, port of entry, and date the authorized period of admission 
expires) valid for multiple entries and who have re-entered multiple 
times. Total entering the United States includes U.S. citizens who may 
have re-entered the country multiple times and foreign nationals, 
including those not issued I-94s, such as Canadian citizens and 
Mexicans with BCCs, and those issued multiple entry I-94s who also may 
have re-entered multiple times. U.S. citizens do not fall within the 
statutory scope of US-VISIT and therefore are exempt from US-VISIT 
screening. 

[End of figure] 

Foreign nationals subject to US-VISIT who intend to enter the country 
encounter different inspection processes at different types of POEs 
depending on their mode of travel. Those who intend to enter the United 
States at an air or sea POE are to be processed, for purposes of US- 
VISIT, in the primary inspection area upon arrival. Generally, these 
visitors are subject to prescreening, before they arrive, via passenger 
manifests, which are forwarded to CBP by commercial air or sea carrier 
in advance of arrival.[Footnote 13] By contrast, foreign nationals 
intending to enter the United States at land POEs are generally not 
subject to prescreening because they arrive in private vehicles or on 
foot and there is no manifest to record their pending arrival. Thus, 
when foreign nationals subject to US-VISIT arrive at a land POE in 
vehicles, they initially enter the primary inspection area where CBP 
officers, often located in booths, are to visually inspect travel 
documents and query the visitors about such matters as their place of 
birth and proposed destination. Visitors arriving as pedestrians enter 
an equivalent primary inspection area, generally inside a CBP building. 
If the CBP officer believes a more detailed inspection is needed or if 
the visitors are required to be processed under US-VISIT, the visitors 
are to be referred to the secondary inspection area--an area away from 
the primary inspection area--which is generally inside a facility. The 
secondary inspection area inside the facility generally contains office 
space, waiting areas, and space to process visitors, including US-VISIT 
enrollees. Equipment used for US-VISIT processing includes a computer, 
printer, digital camera, and a two-fingerprint scanner. Visitors 
covered by US-VISIT who are determined to be admissible are issued an I-
94 arrival/departure form, which, among other things, records their 
date of arrival and the date their authorized period of admission 
expires.[Footnote 14] 

DHS Has Installed US-VISIT Biometric Entry Capability at Nearly All 
POEs, but Faces Challenges Identifying and Monitoring the Operational 
Impacts on Land POE Facilities: 

The US-VISIT program office has largely met its expectations relative 
to a biometric entry capability. For example, on January 5, 2004, it 
deployed and began operating most aspects of its planned biometric 
entry capability at 115 airports and 14 seaports for selected foreign 
nationals, including those from visa waiver countries;[Footnote 15] as 
of December 2006, the program office had deployed and began operating 
this entry capability in the secondary inspection areas of 154 of 170 
land POEs. According to program officials, 14 of the remaining 16 POEs 
have no operational need to deploy US-VISIT because visitors who are 
required to be processed through US-VISIT are, by regulation, not 
authorized to enter into the United States at these locations.[Footnote 
16] The other two POEs do not have entry capability deployed because 
they do not have the necessary transmission lines to operate US-VISIT; 
CBP officers at those sites have continued to process visitors 
manually. CBP officials told us that US-VISIT's entry capability has 
generally enhanced their ability to process visitors subject to US- 
VISIT by providing assurance that visitors' identities can be confirmed 
through biometric identifiers and by automating the paperwork 
associated with processing I-94 arrival/departure forms. 

To the department's credit, the development and deployment of this 
entry capability was largely in accordance with legislative time lines 
and has occurred during a period of considerable organizational change, 
starting with the creation of DHS from 23 separate agencies in early 
2003, followed by the birth of a US-VISIT program office shortly 
thereafter--which was only about 5 months before the program had to 
meet its first legislative milestone. Compounding these program 
challenges was the fact that the systems that were to be used in 
building and deploying a biometric entry capability were managed and 
operated by a number of the separate agencies that had been merged to 
form the new department, each of which was governed by different 
policies, procedures, and standards. 

Moreover, DHS reports that US-VISIT entry capabilities have produced 
results. According to US-VISIT's Consolidated Weekly Summary Report, as 
of December 28, 2006, there have been more than 5,400 biometric hits in 
primary entry, resulting in more than 1,300 people having adverse 
actions, such as denial of entry, taken against them. According to the 
report, about 4,100 of these hits occurred at air and sea ports of 
entry and over 1,300 at land ports of entry. Further, the report 
indicates that more than 1,800 biometric hits have been referred to 
DHS's immigration enforcement unit, resulting in 293 arrests. We did 
not verify the information in the consolidated report. 

Another potential consequence, although difficult to demonstrate, is 
the deterrent effect of having an operational entry capability. 
Although deterrence is not an expressly stated goal of the program, 
officials have cited it as a potential byproduct of having a publicized 
capability at the border to screen entry on the basis of identity 
verification and matching against watch lists of known and suspected 
terrorists. Accordingly, the deterrent potential of the knowledge that 
unwanted entry may be thwarted and the perpetrators caught is arguably 
a layer of security that should not be overlooked. 

Despite these results, US-VISIT's entry capability at land POEs has not 
been without operational and system performance problems. During recent 
visits to land POEs, we identified some space constraints and other 
capacity issues. For example, at the Nogales-Morley Gate POE in 
Arizona, where up to 6,000 visitors are processed daily (and up to 
10,000 on holidays), equipment was installed[Footnote 17] but not used 
because of CBP concerns about its ability to carry out the US-VISIT 
process in a constrained space while thousands of other people not 
subject to US-VISIT are processed through the facility daily.[Footnote 
18] Thus, visitors that are to be processed into US-VISIT from Morley 
Gate are directed to return to Mexico (a few feet away) and to walk 
approximately 100 yards to the Nogales-DeConcini POE facility, which 
has the capability to handle secondary inspections of this kind. 

Going forward, DHS plans to introduce changes and enhancements to US- 
VISIT at land POEs intended to further bolster CBP's ability to verify 
the identity of individuals entering the country, including a 
transition from digitally scanning 2 fingerprints to scanning 10. While 
such changes are intended to further enhance border security, deploying 
them may have an impact on aging and space-constrained land POE 
facilities because they could increase inspection times and adversely 
affect POE operations. Our site visits, interviews with US-VISIT and 
CBP officials, and the work of others suggest that both before and 
after US-VISIT entry capability was installed at land POEs, these 
facilities faced a number of challenges--operational and physical-- 
including space constraints complicated by the logistics of processing 
high volumes of visitors and associated traffic congestion. Moreover, 
our work over the past 3 years showed that the US-VISIT program office 
had not taken necessary steps to help ensure that US-VISIT entry 
capability operates as intended. For example, in February 2006 we 
reported that the approach taken by the US-VISIT Program Office to 
evaluate the impact of US-VISIT on land POE facilities focused on 
changes in I-94 processing time at 5 POEs and did not examine other 
operational factors, such as US-VISIT's impact on physical facilities 
or work force requirements.[Footnote 19] As a result, program officials 
did not always have the information they needed to anticipate problems 
that occurred, such as problems processing high volumes of visitors in 
space-constrained facilities. 

In addition, we found that management controls did not always alert US- 
VISIT and CBP to operational problems. Our standards for internal 
controls in the federal government state that it is important for 
agencies to have controls in place to help ensure that policies and 
procedures are applied and that managers be made aware of problems so 
that that they can be addressed and resolved in a timely 
fashion.[Footnote 20] CBP officials at 12 of 21 land POE sites we 
visited told us about US-VISIT-related computer slowdowns and freezes 
that adversely affected visitor processing and inspection times, and at 
9 of the 12 sites, computer processing problems were not always 
reported to CBP's computer help desk, as required by CBP guidelines. 
Although various controls are in place to alert US-VISIT and CBP 
officials to problems as they occur, these controls did not alert 
officials to all problems, given that they had been unaware of the 
problems we identified before we brought them to their attention. These 
computer processing problems have the potential to not only 
inconvenience travelers because of the increased time needed to 
complete the inspection process, but to compromise security, 
particularly if CBP officers are unable to perform biometric checks-- 
one of the critical reasons US-VISIT was installed at POEs. 

Our internal control standards also call for agencies to establish 
performance measures throughout the organization so that actual 
performance can be compared to expected results. While the US-VISIT 
Program Office established performance measures for fiscal years 2005 
and 2006 intended to gauge performance of various aspects of US-VISIT 
at air, sea, and land POEs in the aggregate, performance measures 
specifically for land POEs had not been developed. It is important to 
do so, given that there are significant operational and facility 
differences among these different types of POEs. Additional performance 
measures that consider operational and facility differences at land 
POEs would put US-VISIT program officials in a better position to 
identify problems, trends, and areas needing improvements. 

Implementing a Biometric US-VISIT Exit Capability has Been a Challenge: 

DHS has devoted considerable time and resources toward establishing an 
operational exit capability. Over the last 4 years, it has committed 
over $160 million to pilot test and evaluate an exit solution at 12 
air, 2 sea, and 5 land POEs. Despite this considerable investment of 
time and resources, the US-VISIT program still does not have either an 
operational exit capability or a viable exit solution to deploy to all 
air, sea, and land POEs. 

A Biometric Exit Capability is being Tested at Air and Sea POEs, But 
Operational Concerns Need to be Addressed: 

Although US-VISIT is pilot testing a biometric exit capability for air 
and sea POEs, it is not currently available at all ports. In January 
2004, devices for collecting biometric data were deployed to one 
airport and one seaport on a pilot basis. Subsequently, this pilot was 
expanded to 12 airports and 2 seaports. The pilot tested several exit 
alternatives, including an enhanced kiosk (a self-service device that 
captures a digital photograph and fingerprint, and prints out an 
encoded receipt), a mobile device (a hand-held device operated by a 
workstation attendant[Footnote 21] that captures a digital photograph 
and fingerprint), and a validator (a hand-held device operated by a 
workstation attendant that captures a digital photograph and 
fingerprint and then matches the captured photograph and fingerprint to 
the ones originally captured via the kiosk and encoded in the receipt). 
Each alternative required the traveler to comply with inspection 
processes. The pilot was completed in May 2005, and established the 
technical feasibility of a biometric exit solution. However, it 
identified issues that limited the operational effectiveness of the 
solution, such as the lack of traveler compliance with the processes. 

The fiscal year 2006 expenditure plan allocated $33.5 million to 
continue the exit pilots for air and sea POEs. According to program 
officials, US-VISIT is now developing a plan for deploying a 
comprehensive, affordable exit solution. However, no time frame has 
been established for this plan being approved or implemented. 
Meanwhile, US-VISIT plans to conduct a second pilot phase at air and 
sea POEs that will involve multiple operational scenarios which would 
compel greater traveler compliance, such as repositioning the kiosks, 
integrating biometric exit into airport check-in processes, integrating 
biometric exit into existing airline processes, integrating biometric 
exit into Transportation Security Administration screening checkpoints, 
and enhancing the use of Immigration and Customs Enforcement programs 
intended for enforcement, such as screening of targeted flights at 
selected airports. 

Various Factors Have Prevented US-VISIT from Implementing a Biometric 
Exit Capability at Land POEs: 

Various factors have prevented US-VISIT from implementing a biometric 
exit capability at land POEs. Federal laws require the creation of a US-
VISIT exit capability using biometric verification methods to ensure 
that the identity of visitors leaving the country can be matched 
biometrically against their entry records.[Footnote 22] However, 
according to officials at the US-VISIT Program Office and CBP and US- 
VISIT program documentation, there are interrelated logistical, 
technological, and infrastructure constraints that have precluded DHS 
from achieving this mandate, and there are cost factors related to the 
feasibility of implementation of such a solution. The major constraint 
to performing biometric verification upon exit at this time, in the US- 
VISIT Program Office's view, is that the only proven technology 
available would necessitate mirroring the processes currently in use 
for US-VISIT at entry. A mirror image system for exit would, like one 
for entry, require CBP officers at land POEs to examine the travel 
documents of those leaving the country, take fingerprints, compare 
visitors' facial features to photographs, and, if questions about 
identity arise, direct the departing visitor to secondary inspection 
for additional questioning. These steps would be carried out for 
exiting pedestrians as well as for persons exiting in vehicles. The US- 
VISIT Program Office concluded in January 2005 that the mirror-imaging 
solution was "an infeasible alternative for numerous reasons, including 
but not limited to, the additional staffing demands, new infrastructure 
requirements, and potential trade and commerce impacts."[Footnote 23] 

US-VISIT officials told us that they anticipated that a biometric exit 
process mirroring that used for entry could result in delays at land 
POEs with heavy daily volumes of visitors. And they stated that in 
order to implement a mirror image biometric exit capability, additional 
lanes for exiting vehicles and additional inspection booths and staff 
would be needed, though they had not determined precisely how many. 
According to these officials, it is unclear how new traffic lanes and 
new facilities could be built at land POEs where space constraints 
already exist, such as those in congested urban areas. (For example, 
San Ysidro, California, currently has 24 entry lanes, each with its own 
staffed booth and 6 unstaffed exit lanes. Thus, if full biometric exit 
capability were implemented using a mirror image approach, San Ysidro's 
current capacity of 6 exit lanes would have to be expanded to 24 exit 
lanes.) As shown in figure 3, based on observations during our site 
visit to the San Ysidro POE, the facility is surrounded by dense urban 
infrastructure, leaving little, if any, room to expand in place. Some 
of the 24 entry lanes for vehicle traffic heading northward from Mexico 
into the United States appear in the bottom left portion of the 
photograph, where vehicles are shown waiting to approach primary 
inspection at the facility; the 6 exit lanes (traffic toward Mexico), 
which do not have fixed inspection facilities, are at the upper left.

Other POE facilities are similarly space-constrained. At the POE at 
Nogales-DeConcini, Arizona, for example, we observed that the facility 
is bordered by railroad tracks, a parking lot, and industrial or 
commercial buildings. In addition, CBP has identified space constraints 
at some rural POEs. For example, the Thousand Islands Bridge POE at 
Alexandria Bay, New York, is situated in what POE officials described 
as a "geological bowl," with tall rock outcroppings potentially 
hindering the ability to expand facilities at the current location. 
Officials told us that in order to accommodate existing and anticipated 
traffic volume upon entry, they are in the early stages of planning to 
build an entirely new POE on a hill about a half-mile south of the 
present facility. CBP officials at the Blaine-Peace Arch POE in 
Washington state said that CBP also is considering whether to relocate 
and expand the POE facility, within the next 5 to 10 years, to better 
handle existing and projected traffic volume. According to the US-VISIT 
program officials, none of the plans for any expanded, renovated, or 
relocated POE include a mirror image addition of exit lanes or 
facilities comparable to those existing for entry. 

In 2003, the US-VISIT Program Office estimated that it would cost 
approximately $3 billion to implement US-VISIT entry and exit 
capability at land POEs where US-VISIT was likely to be installed and 
that such an effort would have a major impact on facility 
infrastructure at land POEs. We did not assess the reliability of the 
2003 estimate. The cost estimate did not separately break out costs for 
entry and exit construction, but did factor in the cost for building 
additional exit vehicle lanes and booths as well as buildings and other 
infrastructure that would be required to accommodate a mirror imaging 
at exit of the capabilities required for entry processing. US-VISIT 
program officials told us that they provided this estimate to 
congressional staff during a briefing, but that the reaction to this 
projected cost was negative and that they therefore did not move ahead 
with this option. No subsequent cost estimate updates had been 
prepared, and DHS's annual budget requests have not included funds to 
build the infrastructure that would be associated with the required 
facilities. 

US-VISIT officials stated that they believe that technological advances 
over the next 5 to 10 years will make it possible to utilize 
alternative technologies that provide biometric verification of persons 
exiting the country without major changes to facility infrastructure 
and without requiring those exiting to stop and/or exit their vehicles, 
thereby precluding traffic backup, congestion, and resulting delays. US-
VISIT's report assessing biometric alternatives noted that although 
limitations in technology currently preclude the use of biometric 
identification because visitors would have to be stopped, the use of 
the as yet undeveloped biometric verification technology supports the 
long-term vision of the US-VISIT program.[Footnote 24] However, no such 
technology or device currently exists that would not have a major 
impact on facilities. The prospects for its development, manufacture, 
deployment, and reliable utilization are currently uncertain or 
unknown, although a prototype device that would permit a fingerprint to 
be read remotely without requiring the visitor to come to a full stop 
is under development. 

While logistical, technical, and cost constraints may prevent 
implementation of a biometrically based exit technology for US-VISIT at 
this time, it is important to note that there currently is not a 
legislatively mandated date for implementation of such a solution. The 
Intelligence Reform and Terrorism Prevention Act of 2004 requires US- 
VISIT to collect biometric exit data from all individuals who are 
required to provide biometric entry data.[Footnote 25] The act did not 
set a deadline, however, for requiring collection of biometric exit 
data from all individuals who are required to provide biometric entry 
data. Although US-VISIT had set a December 2007 deadline for 
implementing exit capability at the 50 busiest land POEs, US-VISIT has 
since determined that implementing exit capability by this date is no 
longer feasible, and a new date for doing so has not been set. 

US-VISIT has tested nonbiometric technology to record travelers' 
departure, but testing showed numerous performance and reliability 
problems. Because there is at present no biometric technology that can 
be used to verify a traveler's exit from the country at land POEs 
without also making major and costly changes to POE infrastructure and 
facilities, US-VISIT tested radio frequency identification (RFID) 
technology as a nonbiometric means of recording visitors as they exit. 
RFID technology can be used to electronically identify and gather 
information contained on a tag--in this case, a unique identifying 
number embedded in a tag on a visitor's arrival/ departure form--which 
an electronic reader at the POE is intended to detect. While RFID 
technology required few facility and infrastructure changes, US-VISIT's 
testing and analysis at five land POEs at the northern and southern 
borders identified numerous performance and reliability problems, such 
as the failure of RFID readers to detect a majority of travelers' tags 
during testing. For example, according to US-VISIT, at the Blaine-
Pacific Highway test site, of 166 vehicles tested during a 1-week 
period, RFID readers correctly identified 14 percent--a sizable 
departure from the target read rate of 70 percent.[Footnote 26] 

Another problem that arose was that of cross-reads, in which multiple 
RFID readers installed on poles or structures over roads, called 
gantries, picked up information from the same visitor, regardless of 
whether the individual was entering or exiting in a vehicle or on foot. 
Thus, cross-reads resulted in inaccurate record keeping. 

Even if RFID deficiencies were to be fully addressed and deadlines set, 
questions remain. For example, the RFID solution did not meet the 
congressional requirement for a biometric exit capability because the 
technology that had been tested cannot meet a key goal of US-VISIT--
ensuring that visitors who enter the country are the same ones who 
leave. By design, an RFID tag embedded in an I-94 arrival/ departure 
form cannot provide the biometric identity-matching capability that is 
envisioned as part of a comprehensive entry/exit border security system 
using biometric identifiers for tracking overstays and others entering, 
exiting, and re-entering the country. Specifically, the RFID tag in the 
I-94 form cannot be physically tied to an individual. This situation 
means that while a document may be detected as leaving the country, the 
person to whom it was issued at time of entry may be somewhere else. 

DHS was to have reported to Congress by June 2005 on how the agency 
intended to fully implement a biometric entry/exit program. In February 
2007, US-VISIT officials told us that this plan had been forwarded to 
the Office of Management and Budget (OMB) for review. According to 
statute, this plan is to include, among other things, a description of 
the manner in which the US-VISIT program meets the goals of a 
comprehensive entry and exit screening system--including both biometric 
entry and exit--and fulfills statutory obligations imposed on the 
program by several laws enacted between 1996 and 2002.[Footnote 27] 
Until such a plan is finalized and issued, DHS is not able to 
articulate how entry/exit concepts will fit together--including any 
interim nonbiometric solutions--and neither DHS nor Congress is 
positioned to prioritize and allocate resources for a US-VISIT exit 
capability or plan for the program's future. 

DHS Continues to Face Longstanding US-VISIT Management Challenges and 
Future Uncertainties: 

Our work and other best practice research have shown that applying 
disciplined and rigorous management practices improves the likelihood 
of delivering expected capabilities on time and within budget. Such 
practices and processes include determining how the program fits within 
the larger context of an agency's strategic plans and related 
operational and technology environments, whether the program will 
produce benefits in excess of costs over its useful life, and whether 
program impacts and options are being fully identified, considered, and 
addressed. To further ensure that programs are managed effectively, it 
is important that they be executed in accordance with acquisition and 
financial management requirements and best practices, and that progress 
against program commitments is defined and measured so that program 
officials can be held accountable for results. 

Over the last several years, we have reported on fundamental 
limitations in DHS's efforts to define and justify the program's future 
direction and to cost-effectively manage the delivery of promised 
capabilities on time and within budget. To a large degree, what is 
operating and what is not operating today, and what future program 
changes are underway and yet to be defined, are affected by these 
limitations. DHS needs to address these challenges going forward, and 
the recommendations that we made are aimed at encouraging this. Until 
these recommendations are fully implemented, the program will be at 
greater risk of not optimally meeting mission needs and falling short 
of meeting expectations. 

DHS Has Not Defined and Developed US-VISIT Within a DHS-wide 
Operational and Technological Context: 

As we previously reported, agency programs need to properly fit within 
a common strategic context or frame of reference governing key aspects 
of program operations (such as who is to perform what functions, when 
and where they are to be performed, what information is to be used to 
perform them, and what rules and standards will govern the use of 
technology to support them).[Footnote 28] Without a clear operational 
context to guide and constrain both US-VISIT and other border security 
and immigration enforcement initiatives, DHS risks investing in 
programs and systems that are duplicative, are not interoperable, and 
do not optimize enterprisewide mission operations and produce intended 
outcomes. 

For almost 4 years, DHS has continued to pursue US-VISIT (both in terms 
of deploying interfaces between and enhancements to existing systems 
and in defining a longer-term, strategic US-VISIT solution) without 
producing the program's operational context. In September 2003, we 
reported that DHS had not defined key aspects of the larger homeland 
security environment in which US-VISIT would need to operate. In the 
absence of a DHS-wide operational and technological context, program 
officials were making assumptions about certain policy and standards 
decisions that had not been made, such as whether official travel 
documents would be required for all persons who enter and exit the 
country--including U.S. and Canadian citizens--and how many 
fingerprints would be collected for biometric comparisons. We further 
reported that if the program office's assumptions and decisions turned 
out to be inconsistent with subsequent policy or standards decisions, 
it would require US-VISIT rework. 

According to the program's Chief Strategist, an immigration and border 
management strategic plan was drafted in March 2005 to show how US- 
VISIT is aligned with DHS's organizational mission and to define an 
overall vision for immigration and border management. According to this 
official, the vision provides for an immigration and border management 
enterprise that unifies multiple departmental and external stakeholders 
around common objectives, strategies, processes, and infrastructures. 
As of February 2007, about 2 years later, we were told that this 
strategic plan has not yet been approved, although the program's Acting 
Director stated that the plan is currently with OMB and should be 
provided to the House and Senate Appropriations Subcommittees on 
Homeland Security by March 2007. 

However, at the same time, US-VISIT has not taken steps to ensure that 
the direction that it is taking is both operationally and 
technologically aligned with DHS's enterprise architecture (EA). As the 
report that we issued this week states, the DHS Enterprise Architecture 
Board, which is the DHS entity that determines EA compliance, has not 
reviewed the US-VISIT architecture compliance for more than 2 years. 
However, since August 2004, both US-VISIT and the EA have changed. For 
example, additional functionality, such as the interoperability of US- 
VISIT's Automated Biometric Information System (IDENT) and the 
Department of Justice's Integrated Automated Fingerprint Identification 
System (IAFIS), and the expansion of IDENT to collect t10 rather than 2 
fingerprints, has been added. Also, two versions of the DHS EA have 
been issued since August 2004. 

While the strategic plan has not been approved or disseminated, the 
program office has developed a strategic vision and blueprint and begun 
to implement it. According to program officials, this future vision is 
to be delivered through a number of planned mission capability 
enhancements. Of these, the first enhancement is underway and is to 
provide several new capabilities, including what the program refers to 
as "Unique Identity," which is to include the migration from the 2- 
fingerprint to 10-fingerprint collection at program enrollment. It is 
also to interoperate US-VISIT's IDENT system and the Department of 
Justice's IAFIS system. Currently, the US-VISIT officials plan to 
complete Unique Identity in several phases and have it fully 
operational by December 2009, although these plans have not yet 
approved by DHS. 

At this same time, DHS has launched other major border security 
programs without adequately defining the relationships to US-VISIT and 
each other. For example, the Intelligence Reform and Terrorism 
Prevention Act of 2004 directs DHS and the Department of State to 
develop and implement a plan, no later than June 2009, that requires 
U.S. citizens and foreign nationals of Canada, Bermuda, and Mexico to 
present a passport or other document or combination of documents deemed 
sufficient to show identity and citizenship to enter the United States 
(this is currently not a requirement for these individuals entering the 
United States via sea and land POEs from most countries within the 
western hemisphere).[Footnote 29] This effort, known as the Western 
Hemisphere Travel Initiative, was first announced in 2005. In May 2006, 
we reported that DHS and the Department of State had taken some steps 
to carry out the initiative, but they had a long way to go to implement 
their proposed plans.[Footnote 30] Among other things, key decisions 
had yet to be made about what documents other than a passport would be 
acceptable when U.S. citizens and citizens of Canada enter or return to 
the United States. Further, while DHS and Department of State had 
proposed an alternative form of passport, called a PASS card, that 
would rely on RFID technology to help DHS process U.S. citizens re- 
entering the country, DHS had not made decisions involving a broad set 
of considerations that include (1) utilizing security features to 
protect personal information, (2) ensuring that proper equipment and 
facilities are in place to facilitate crossings at land borders, and 
(3) enhancing compatibility with other border crossing technology 
already in use. 

DHS has also initiated another border security program, known as the 
Secure Border Initiative (SBI)--a multi-year, multi-billion dollar 
program, to secure the borders and reduce illegal immigration by 
installing state-of-the-art surveillance technologies along the border, 
increasing border security personnel, and ensuring information access 
to DHS personnel at and between POEs. Under SBI and its component, 
called SBInet, DHS plans to integrate personnel, infrastructures, 
technologies, and rapid response capability into a comprehensive border 
protection capability. DHS reports that, among other things, SBInet is 
to encompass both the northern and southern land borders, including the 
Great Lakes, under a unified border control strategy whereby CBP is to 
focus on the interdiction of cross-border violations between and at the 
land POEs, funneling traffic to the land POEs. As part of SBI, DHS also 
plans to focus on interior enforcement--disrupting and dismantling 
cross-border crime into the interior of the United States while 
locating and removing aliens who are present in the United States in 
violation of law. However, it is unclear how SBInet will be linked, if 
at all, to US-VISIT so that the two can share technology, 
infrastructure, and data. 

Clearly defining the dependencies among US-VISIT and programs like the 
Western Hemisphere Travel Initiative and SBI is important because there 
is commonality among their strategic goals and operational 
environments. For example, both US-VISIT and SBI share the goal of 
securing the POEs. Moreover, there is overlap in the data that each is 
to produce and use. For example, both US-VISIT and the Western 
Hemisphere Travel Initiative will require identification data for 
travelers at POEs. 

Despite these dependencies, DHS has yet to define these relationships 
or how they will be managed. Further, according to a March 6, 2006 memo 
from the DHS Joint Requirements Council, the US-VISIT strategic plan 
did not provide evidence of sufficient coordination between the program 
and the other entities involved in border security and immigration 
efforts. The council's recommendation was that the strategic plan not 
be approved until greater coordination between US-VISIT and other 
components was addressed. 

According to the Acting Program Director, a number of efforts are 
underway to coordinate with other entities, such as with CBP on RFID, 
with the Coast Guard on development of a mobile biometric reader, and 
with State on standards for document readers. Without a clear, 
complete, transparent, and understood definition of how related 
programs and initiatives are to interact, US-VISIT and other border 
security and immigration enforcement programs run the risk of being 
defined and implemented in a way that does not optimize DHS-wide 
performance and results. 

DHS Has Not Economically Justified US-VISIT Increments or Assessed 
Their Operational Impacts: 

The decision to invest in any system or capability should be based on 
reliable analyses of return on investment. That is, an agency should 
have reasonable assurance that a proposed program will produce mission 
value commensurate with expected costs and risks. According to OMB 
guidance, individual increments of major systems should be individually 
supported by analyses of benefits, cost, and risk. Thus far, DHS has 
yet to develop an adequate basis for knowing whether its incrementally 
deployed US-VISIT capabilities represent a good return on investment, 
particularly in light of shortfalls in DHS's assessments of the 
program's operational impacts, including costs of proposed 
capabilities. Without this knowledge, DHS will not know until after the 
fact whether it is investing wisely or pursuing cost-effective and 
affordable solutions. 

DHS Did Not Economically Justify Its Proposed Incremental Investments: 

US-VISIT had not assessed the cost and benefits of its early 
increments. For example, we reported in September 2003 that it had not 
assessed the costs and benefits of Increment 1. Again, in February 
2005, we reported that although the program office developed a cost- 
benefit analysis for its land entry capability, it had not justified 
the investment because the treatment of both benefits and costs were 
unclear and insufficient. Further, we reported that the cost estimates 
on which the cost-benefit analysis was based were of questionable 
reliability because effective cost-estimating practices were not 
followed. Most recently, in February 2006, we reported again that the 
program office had not justified its investment in its air and sea exit 
capability. For example, we reported that while the cost-benefit 
analysis explained why the investment was needed, and considered at 
least two alternatives to the status quo, which is consistent with OMB 
guidance for cost-benefit analyses, it did not include a complete 
uncertainty analysis for the three exit alternatives evaluated. 
Specifically, it did not include a sensitivity analysis[Footnote 31] 
for the three alternatives, which is a major part of an uncertainty 
analysis. A complete analysis of uncertainty is important because it 
provides decision makers with a perspective on the potential 
variability of the cost and benefit estimates should the facts, 
circumstances, and assumptions change. Further, the cost estimate upon 
which the analysis was based did not meet key criteria for reliable 
cost estimating. For example, it did not include a detailed work 
breakdown structure, which serves to organize and define the work to be 
performed so that associated costs can be identified and estimated. 

Further, as we state in our February 2007 report, DHS has devoted 
considerable time and resources toward establishing an operational exit 
capability at land, air, and sea POEs. For example, over the last 4 
years, DHS has committed over $160 million to evaluate and operate exit 
pilots at selected air, sea, and land POEs. Notwithstanding this 
considerable investment of time and resources, the US-VISIT program 
still does not have either an operational exit capability or a viable 
exit solution to deploy to all air, sea, and land POEs. 

Moreover, US-VISIT exit pilot reports have raised concerns and 
limitations. For example, as we previously stated, land exit pilots 
experienced several performance problems, such as the failure of RFID 
readers to detect a majority of travelers' tags during testing and 
cross-reads, in which multiple RFID readers installed on poles or 
structures over roads, called gantries, picked up information from the 
same visitor. 

Notwithstanding these results, we reported in February 2007 that the 
program office planned to invest another $33.5 million to continue its 
air and sea exit pilots. However, neither the fiscal year 2006 
expenditure plan nor other exit-related program documentation 
adequately defined what these efforts entail or what they will 
accomplish. In particular, the plan and other exit-related 
documentation merely state that $33.5 million will be used to continue 
air and sea exit pilots while a comprehensive exit solution is 
developed. They do not adequately describe measurable outcomes 
(benefits and results) from the pilot efforts, or related cost, 
schedule, and capability commitments that will be met. Further, the 
plan does not recognize the challenges revealed from the prior exit 
efforts, nor does it show how proposed exit investments address these 
challenges. In addition, the plan allocates more funding for continuing 
the air and sea exit pilots ($33.5 million) than the prior year's plan 
said would be needed to fully deploy an operational air and sea exit 
solution ($32 million). According to program officials, the air and sea 
exit pilots are being continued to maintain a presence intended to 
provide a deterrent effect at exit locations, and to gather additional 
data that could help support planning for a comprehensive exit 
solution. 

Moreover, US-VISIT reported in August 2006 that it planned to spend an 
additional $21.5 million to continue its land exit demonstration 
project without adequate justification. However, we reported in 
February 2007 that these plans lacked adequate justification in light 
of the problems we discussed earlier in this statement. Accordingly, 
program officials told us that they intend to terminate the land exit 
project until a comprehensive exit strategy can be developed. They have 
also stated that a small portion of the $21.5 million is to be used to 
close out the demonstration project and have requested that the 
remainder of the money be reprogrammed to support Unique Identity. 

DHS Did Not Adequately Assess the Impact of Entry Capabilities on Land 
Ports of Entry Operations and Planned Capability Enhancements Carry 
Potential Cost Implications: 

Knowing how planned US-VISIT capabilities will impact POE operations is 
critical to US-VISIT investment decision makers. In May 2004, we 
reported that the program had not assessed how deploying entry 
capabilities at land POEs would impact the workforce and facilities. We 
questioned the validity of the program's assumptions and plans 
concerning workforce and facilities, since the program lacked a basis 
for determining whether its assumptions were correct and thus whether 
its plans were adequate. Subsequently, the program office evaluated the 
operational performance of the land entry capability with the stated 
purpose of determining the effectiveness of its performance at the 50 
busiest land POEs. For this evaluation, the program office established 
a baseline for comparing the average time it takes to issue and process 
entry/exit forms at 3 of these 50 POEs, and then conducted two 
evaluations of the processing times at the three POEs, one after the 
entry capability was deployed as a pilot, and another one 3 months 
later, after the entry capability was deployed to all 50 POEs. The 
evaluation results showed that the average processing times decreased 
for all three sites. Program officials concluded that these results 
supported their workforce and facility investment assumptions that no 
additional staff was required to support deployment of the entry 
capability and that minimal modifications were required at the 
facilities.[Footnote 32] 

However, the scope of the evaluations was not sufficient to satisfy the 
evaluations' stated purpose for assessing the full impact of the entry 
capability. For example, the selection of the three sites, according to 
program officials, was based on a number of factors, including whether 
the sites already had sufficient staff to support the pilot. Selecting 
sites based on this factor is problematic because it presupposes that 
all not POEs have the staff needed to support the land entry 
capability. In addition, evaluation conditions were not always held 
constant: specifically, fewer workstations were used to process 
travelers in establishing the baseline processing times at two of the 
POEs than were used during the pilot evaluations. 

Moreover, CBP officials from a land port of entry that was not an 
evaluation site (San Ysidro) told us that US-VISIT deployment had not 
reduced but actually lengthened processing times. (San Ysidro processes 
the highest volume of travelers of all land POEs.) Although these 
officials did not provide specific data to support their statement, 
their perception nevertheless raises questions about the potential 
impact of land entry capabilities on the 47 sites that were not 
evaluated. 

Exacerbating this situation is the fact that DHS plans to introduce 
changes and enhancements to US-VISIT at land POEs to verify the 
identity of individuals entering the country, including a transition 
from digitally scanning 2 fingerprints to 10. While such changes are 
intended to further enhance border security, deploying them may have an 
impact on aging and spatially-constrained land POEs facilities because 
they could increase inspection times and adversely affect POEs 
operations. Moreover, the increase from 2 to 10 fingerprints can affect 
the capacity of the systems and communications networks processing 
because of the larger data sets being processed and transmitted (10 vs 
2 fingerprints). This need for increased capacity will in turn affect 
program costs. 

US-VISIT Did Not Adequately Evaluate Exit Capability Impacts on 
Operations at Air and Sea Ports of Entry: 

The impact of planned exit capabilities at air and sea POEs has also 
not been adequately analyzed, and is thus not available to inform 
investment decisions. In February 2005, we reported that the program 
office had not adequately planned for evaluating its exit pilot at air 
and sea POEs because the pilot's evaluation scope and timeline were 
compressed. As a result, the US-VISIT program office extended the pilot 
from 5 to 14 POEs (12 airports and 2 seaports). Notwithstanding the 
expanded scope of the pilot, the exit alternatives were not 
sufficiently evaluated. Specifically, the program office evaluated 
these alternatives against three criteria,[Footnote 33] including 
compliance with the exit process. According to the exit evaluation plan 
report, the average compliance rate across all three alternatives was 
only 24 percent.[Footnote 34] The evaluation report cited several 
reasons for the low compliance rate, including that compliance during 
the pilot was voluntary. As a result, the evaluation report concluded 
that national deployment of the exit solution will not meet the desired 
compliance rate unless the scope of the exit process is expanded to 
incorporate an enforcement mechanism, such as not allowing persons to 
reenter the United States if they do not comply with the exit process 
or not allowing persons to board a carrier until they are processed by 
an airline or the Transportation Security Administration. As of 
February 2006, program officials had not conducted any formal 
evaluation of enforcement mechanisms or their possible effect on 
compliance and cost, and according to the Acting Program Director, they 
do not plan to do so. 

DHS Has Not Adequately Justified Increases in, and Disclosed the Scope 
and Nature of, Program Management-Related Fiscal Year 2006 
Expenditures: 

Program management is an important and integral aspect of any system 
acquisition program. The importance of program management, however, 
does not by itself justify any level of investment in such activities. 
Rather, investments in program management capabilities should be viewed 
the same as investments in any program capability, meaning the scope, 
nature, size, and value of the investment should be disclosed and 
justified in relation to the size and significance of the acquisition 
activities being performed. 

As our February 2007 report states, US-VISIT's planned investment in 
program management-related activities has risen steadily over the last 
4 years, while planned investment in development of new program 
capabilities has declined. Figure 3 shows the breakdown of planned 
expenditures for US-VISIT fiscal year 2002 through 2006 expenditure 
plans. 

Figure 3: US-VISIT Breakdown of Planned Expenditures as a Dollar Amount 
for FY2002 Through FY2006:

Source: GAO analysis based on US-VISIT data. 

Note: According to US-VISIT program officials, actual cost information 
for program management and operations cannot be readily provided due to 
limitations in their financial management system. 

[End of figure] 

Specifically, the fiscal year 2003 expenditure plan provided $30 
million for program management and operations and about $325 million 
for new development efforts, whereas the fiscal year 2006 plan provided 
$126 million for program management-related functions--an increase of 
$96 million--and $93 million for new development. This means that the 
fiscal year 2006 plan proposed expending $33 million more for program 
management and operations than it is for new development. 

The increase in planned program management-related expenditures is more 
pronounced if it is viewed as a percentage of planned development 
expenditures. Figure 4 shows planned US-VISIT expenditures for program 
management and operations as a percentage of development for fiscal 
years 2002 thru 2006.

Operations as a Percentage of Development for FY2002 through FY2006:

[Note: According to us-visit program officials, actual cost information 
for program management and operations cannot be readily provided due to 
limitations in their financial management system.  

[End of figure] 

Specifically, planned program management-related expenditures 
represented about 9 percent of planned development in fiscal year 2003, 
but represented about 135 percent of fiscal year 2006 development, 
meaning that the fiscal year 2006 expenditure plan proposed spending 
about $1.35 on program management-related activities for each dollar 
spent on developing new US-VISIT capability. 

Moreover, the fiscal year 2006 expenditure plan did not explain the 
reasons for this recent growth or otherwise justify the sizeable 
proposed investment in program management and operations on the basis 
of measurable and expected value. Further, the plan did not adequately 
describe the range of planned program management and operations 
activities. 

Program officials told us that the DHS Acting Undersecretary for 
Management raised similar concerns about the large amount of program 
management and operations funding in the expenditure plan. In January 
2007, DHS submitted a revised expenditure plan to the House and Senate 
Appropriations Subcommittees on Homeland Security, at the committee’s 
direction, to address their concerns. The revised plan allocates some 
program management funds to individual increments and to two new 
categories--program services and data integrity and biometric support, 
and program and project support contractor services. However, the 
revised plan still shows a relatively sizeable portion of proposed 
funding going toward program management-related activities.

DHS Has Not Fully Implemented Key US-VISIT Acquisition and Financial 
Management Controls: 

Managing major programs like US-VISIT requires applying discipline and 
rigor when acquiring and accounting for systems and services. Our work 
and other best practice research have shown that applying such rigorous 
management practices improves the likelihood of delivering expected 
capabilities on time and within budget. In other words, the quality of 
IT systems and services is largely governed by the quality of the 
management processes involved in acquiring and managing them. Some of 
these processes and practices are embodied in the Software Engineering 
Institute's (SEI) Capability Maturity Models®, which define, among 
other things acquisition process management controls that, if 
implemented effectively, can greatly increase the chances of acquiring 
systems that provide promised capabilities on time and within budget. 
Other practices are captured in OMB guidance, which establishes 
policies for planning, budgeting, acquisition, and management of 
federal capital assets. 

Over the last several years, we have made numerous recommendations 
aimed at strengthening US-VISIT program management controls relative to 
acquisition management, including for example configuration management, 
security and privacy management, earned value management 
(EVM),[Footnote 35] and contract tracking and oversight. 

The program office has taken steps to lay the foundation for 
establishing several of these controls. For example, the program 
adopted the SEI Capability Maturity Model Integration (CMMI®)[Footnote 
36] to guide its efforts to employ effective acquisition management 
practices, and approved an acquisition management process improvement 
plan dated May 16, 2005. The goal, as stated in the plan, was to 
conduct an independent CMMI assessment in October 2006 to affirm that 
requisite process controls were in place and operating. 

In September 2005, the program office completed an initial assessment 
of 13 key acquisition process areas that revealed a number of 
weaknesses. To begin addressing these weaknesses, the program office 
narrowed the scope of the process improvement activities from 13 to 6 
(project planning, project monitoring and control, requirements 
development and management, configuration management, product and 
process quality assurance, and risk management) of the CMMI process 
areas and revised its process improvement plan in April 2006 to reflect 
these changes. In May 2006, the program conducted a second internal 
assessment of the six key process areas, and according to the results 
of this assessment, improvements were made, but weaknesses remained in 
all six process areas. For example, 

* a number of key acquisition management documents were not adequately 
prepared and processes were not sufficiently defined, including those 
related to systems development, budget and finance, facilities, and 
strategic planning (e.g., product work flow among organizational units 
was unclear and not documented); and: 

* roles, responsibilities, work products, expectations, resources, and 
accountability of external stakeholder organizations were not well- 
defined. 

Notwithstanding these weaknesses, program officials told us that their 
self-assessments show that they have made incremental progress in 
implementing the 113 practices associated with the six key processes. 
(See figure 5 for US-VISIT's progress in implementing these practices.) 
However, they also recently decided to postpone indefinitely the 
planned October 2006 independent appraisal. Instead, the program 
intends to perform quarterly internal assessments until the results 
show that they can pass an independent appraisal. Further, the program 
has not committed to a revised target date for having an external 
appraisal.

[End of figure] 

The acquisition management weaknesses in the six key process areas are 
exacerbated by weaknesses in other areas. For example, we recently 
reported[Footnote 37] that the US-VISIT contract tracking and oversight 
process suffers from a number of weaknesses. Specifically, we reported 
that the program had not effectively overseen US-VISIT-related contract 
work performed on its behalf by other DHS and non-DHS agencies, and 
these agencies did not always establish and implement the full range of 
controls associated with effective management of contractor activities. 
Further, the program office and other agencies did not implement 
effective financial controls.[Footnote 38] In particular, the program 
office and other agencies managing US-VISIT-related work were unable to 
reliably report the scope of contracting expenditures. In addition, 
some agencies improperly paid and accounted for related invoices, 
including making a duplicate payment and making payments for non-US- 
VISIT services from funds designated for US-VISIT. 

Fully and effectively implementing the above discussed key acquisition 
management and related controls takes considerable time. However, 
considerable time has elapsed since we first recommended establishment 
of these controls and they are not yet operational and it is unclear 
when they will be. Therefore, it is important that these improvement 
efforts stay on track. Until these capabilities are in place, the 
program risks not meeting its stated goals and commitments. 

US-VISIT has not yet implemented other key management practices, such 
as developing and implementing a security plan and employing an EVM 
system to help manage and control program cost and schedule. As we 
previously reported, the program's 2004 security plan generally 
satisfied OMB and the National Institute of Standards and Technology 
security guidance. Further, the fiscal year 2006 expenditure plan 
states that all of the US-VISIT component systems have been certified 
and accredited and given full authority to operate. However, the 2004 
security plan preceded the US-VISIT risk assessment, which was not 
completed until December 2005, and the security plan was not updated to 
reflect this risk assessment. According to program officials, they 
intend to develop a security strategy by the end of 2006 that reflects 
the risk assessment. We have ongoing work for the Senate Committee on 
Homeland Security and Governmental Affairs to review the information 
security controls associated with computer systems and networks 
supporting the US-VISIT program. 

Regarding EVM, the program is currently relying on the prime 
contractor's EVM system to manage the prime contractor's progress 
against cost and schedule goals. According to the fiscal year 2006 
expenditure plan, the program office has assessed the prime 
contractor's EVM system against relevant standards. However, in 
reality, this EVM system was self-certified by the prime contractor in 
December 2003 as meeting established standards. OMB requires that 
agencies verify contractor self-certifications. The program office has 
yet to do this, although program officials told us that they plan to 
retain the services of another contractor to perform this validation. 
This needs to be done quickly. Our review of the integrated baseline 
review, which agencies are required by OMB to complete to ensure that 
the EVM program baseline is accurate, showed that it did not address 
key baseline considerations, such as cost and schedule risks. Moreover, 
other US-VISIT contractors have not been required to use EVM, although 
program officials told us that this was to change effective October 1, 
2006. 

DHS Has Yet to Establish Effective Program Accountability Mechanisms: 

To ensure that programs manage their performance effectively, it is 
important that they define and measure progress against program 
commitments and hold themselves accountable for results. Measurements 
of the operational performance, progress, and results are important to 
reasonably ensure that problems and shortfalls can be addressed and 
resolved in a timely fashion and so that responsible parties can be 
held accountable. 

More specifically, to permit meaningful program oversight, it is 
important that expenditure plans describe how well DHS is progressing 
against the commitments made in prior expenditure plans. However, US- 
VISIT's expenditure plan for fiscal year 2006 (the fifth expenditure 
plan) continued a longstanding pattern of not describing progress 
against commitments made in previous plans. For example, according to 
the fiscal year 2005 expenditure plan, the prime contractor was to 
begin integrating the long-term Increment 4 strategy into the interim 
US-VISIT system's environment and the overall DHS enterprise 
architecture, and that US-VISIT and the prime contractor would work 
with the stakeholder community to identify opportunities for delivery 
of long-term capabilities under Increment 4. However, the fiscal year 
2006 plan does not discuss progress or accomplishments relative to 
these commitments. 

Additionally, the expenditure plan committed to begin deploying the 
most effective exit alternative for capturing biometrics at air and sea 
POEs during fiscal year 2005. In contrast, the 2006 expenditure plan 
states that the exit pilots will continue throughout fiscal year 2006 
and does not address whether the fiscal year 2005 schedule deployment 
commitment was met. Also, the fiscal year 2006 expenditure plan did not 
address all performance measures cited in the fiscal year 2005 plan. 
Specifically, the 2005 plan included 11 measures. In contrast, the 2006 
plan listed 7 measures, 4 of which are similar, but not identical to, 
some of the 11 measures in the 2005 plan. This means that several of 
the 2005 plan's measures are not addressed in the 2006 plan. Moreover, 
even in cases of similar performance measures, the fiscal year 2006 
plan does not adequately describe progress in meeting commitments. For 
example, the fiscal year 2005 expenditure plan cited a performance 
measurement of "Pre-entry watch list hits on biometrically enabled visa 
applications." The fiscal year 2006 plan cites the performance measure 
of "Number of biometric watch list hits for visa applicants processed 
at consular offices." According to the latter plan, in fiscal year 2005 
there were 897 such hits; however, neither plan cites a performance 
target against which to gauge progress, assuming that the two 
performance measures mean the same thing. Without such measurements, 
program performance and accountability can suffer. 

Concluding Observations: 

Developing and deploying complex technology that records the entry and 
exit of millions of visitors to the United States, verifies their 
identities to mitigate the likelihood that terrorists or criminals can 
enter or exit at will, and tracks persons who remain in the country 
longer than authorized is a worthy goal in our nation's effort to 
enhance border security in a post-9/11 era. But doing so also poses 
significant challenges; foremost among them is striking a reasonable 
balance between US-VISIT's goals of providing security to U.S. citizens 
and visitors while facilitating legitimate trade and travel. 

DHS has made considerable progress making the entry portion of the US- 
VISIT program at air, sea and land POEs operational, but our work 
raised questions whether DHS has adequately assessed how US-VISIT has 
affected operations at land POEs. Because US-VISIT will likely continue 
to have an impact on land POE facilities as it evolves--especially as 
new technology and equipment are introduced--it is important for US- 
VISIT and CBP officials to have sufficient management controls for 
identifying and reporting potential computer and other operational 
problems that could affect the ability of US-VISIT entry capability to 
operate as intended. 

With respect to DHS's effort to create an exit verification capability, 
developing and deploying this capability at land POEs has posed a set 
of challenges that are distinct from those associated with entry. US- 
VISIT has not determined whether it can achieve, in a realistic time 
frame, or at an acceptable cost, the legislatively mandated capability 
to record the exit of travelers at land POEs using biometric 
technology. Apart from acquiring new facilities and infrastructure at 
an estimated cost of billions of dollars, US-VISIT officials have 
acknowledged that no technology now exists to reliably record 
travelers' exit from the country, and to ensure that the person leaving 
the country is the same person who entered, without requiring that 
person to stop upon exit--potentially imposing a substantial burden on 
travelers and commerce. US-VISIT officials stated that they believe a 
biometrically based solution that does not require those exiting the 
country to stop for processing, that minimizes the need for major 
facility changes, and that can be used to definitively match a 
visitor's entry and exit will be available in 5 to 10 years. In the 
interim, it remains unclear how DHS plans to proceed. According to 
statute, DHS was required to report more than a year ago on its plans 
for developing a comprehensive biometric entry and exit system, but DHS 
has yet to finalize this road map for Congress. Until DHS finalizes 
such a plan, neither Congress nor DHS is likely to have sufficient 
information as a basis for decisions about various factors relevant to 
the success of US-VISIT, ranging from funding needed for any land POE 
facility modifications in support of the installation of exit 
technology to the trade-offs associated with ensuring traveler 
convenience while providing verification of travelers' departure 
consistent with US-VISIT's national security and law enforcement goals. 

Fundamental questions about the program's future direction and fit 
within the larger homeland security context as well as its return on 
investment remain unanswered. Moreover, the program is overdue in 
establishing the means to ensure that it is pursuing the right US-VISIT 
solution, and that it is managing it the right way. The longer the 
program proceeds without these, the greater the risk that the program 
will not optimally support mission operations and will fall short of 
commitments. Measuring and disclosing the extent to which these 
commitments are being met are also essential to holding the department 
accountable. We look forward to continuing to work constructively with 
the US-VISIT program to better ensure the program's success. 

This concludes my prepared testimony. I would be happy to respond to 
any questions that Members of the Committee may have.

FOOTNOTES 

[1] A port of entry is generally a physical location, such as a 
pedestrian walkway and/or a vehicle plaza with booths, and associated 
inspection and administration buildings, at a land border crossing 
point, or a restricted area inside an airport or seaport, where entry 
into the country by persons and cargo arriving by air, land, or sea is 
controlled by U.S. Customs and Border Protection. 

[2] The Visa Waiver Program enables nationals of certain countries to 
travel to the United States for tourism or business for stays of 90 
days or less without obtaining a visa. Most western European countries 
participate in this program, along with Japan, Singapore, Australia, 
Brunei, and New Zealand. 

[3] To visit the United States, Mexican citizens generally need either 
a Mexican passport and U.S. visa, or a Border Crossing Card (BCC), 
which is issued to Mexican visitors who wish to enter the country for 
business or pleasure for no more than 6 months. The BCC contains 
machine-readable biographic and biometric information. Mexican citizens 
with BCCs who are traveling within 25 miles of the border, (75 miles in 
Arizona, if entering through certain POEs near Tucson) and who plan to 
stay no more than 30 days, are generally not subject to US- VISIT 
processing upon entry. A Mexican citizen is subject to US-VISIT 
requirements, however, if a CBP officer determines that the entrant 
intends to stay more than 30 days or travel beyond the 25-or 75-mile 
limit. 

[4] On July 27, 2006, DHS issued a Notice of Proposed Rulemaking that, 
if finalized, would expand the scope of US-VISIT to include, among 
others, lawful permanent residents, aliens seeking admission on 
immigrant visas, refugees and asylees, and certain categories of 
Canadians. DHS did not report how many additional persons would be 
covered by US-VISIT if the rule was adopted.

[12] Since the statute governing US-VISIT applies to foreign national 
arrival and departure data only, U.S. citizens do not fall within the 
scope of the program and therefore are exempt from US-VISIT screening. 
Also, in general, regardless of whether they are to be processed into 
US-VISIT, Mexican citizens must present either a passport and visa or a 
BCC when seeking admission to the United States, while Canadian 
citizens generally do not need such documents at this time (Canadian 
visitors at land POEs may need passports as early as January 2008, 
however, under regulations implementing a new statutory provision on 
passport requirements). According to US-VISIT, when a Mexican receives 
a BCC, the data on the individual entered into U.S. databases at the 
time of their visa application are accessible by US-VISIT--if they are 
to be processed into it for any reason. 

[13] Under the Enhanced Border Security and Visa Entry Reform Act of 
2002 (Pub. L. No. 107-173, § 402(a), 116 Stat. 543, 557-59), commercial 
air and sea carriers are to transmit crew and passenger manifests to 
appropriate immigration officials before arrival of an aircraft or 
vessel in the United States. These manifests are transmitted to CBP 
through the Advanced Passenger Information System (APIS), which helps 
officers identify (1) those arrivals for which biometric data are 
available and (2) foreign nationals who need to be scrutinized more 
closely. 

[14] Visitors traveling on nonimmigrant visas are issued Form I-94 and 
visitors from Visa Waiver Program countries are issued Form I-94W. Both 
forms show the date of arrival, port of entry, and date the authorized 
period of admission expires. At land border POEs, the Form I-94 issued 
to foreign nationals covered by US-VISIT who are deemed admissible is 
considered issued for multiple entries, unless specifically annotated 
otherwise. A multiple entry I-94 permits them to re-enter the country, 
generally for up to 6 months, without additional US-VISIT processing 
during the period covered by the I-94. 

[15] On September 30, 2004, US-VISIT expanded biometric entry 
procedures to include individuals from visa waiver countries applying 
for admission. 

[16] According to CBP, these POEs are classified as Class B ports. 
Under 8 C.F.R. §100.4 (c) (2), only citizens of the United States, 
Canada, and Bermuda, and Lawful Permanent Residents of the United 
States and certain holders of border crossing cards may enter through 
Class B ports. 

[17] Such equipment includes a computer, printer, digital camera, and 
fingerprint scanners. 

[18] CBP based this decision on the high volume of pedestrians entering 
the United States through the Morley Gate POE; the fact that, before 
deployment, I-94s had not been previously issued at the Morley Gate 
POE; and the close proximity of the Morley Gate POE facility to the 
nearby DeConcini POE facility, about 100 yards away.
