Office of the Inspector General
Profile of the Social Security Administration's Non-Work
Alien File (Limited Distribution) (A-14-03-23071)
Our objective was to analyze the Social Security Administration's
(SSA) Non-Work Alien (NWALIEN) file for Tax Year (TY) 2000 to describe
individuals whose identities, Social Security number (SSN) and earnings
were recorded on the file and to determine how long they have been
working.
Each year, SSA informs the Bureau of Citizenship and
Immigration Services (BCIS) of non-citizens who are potentially
working illegally. SSA sends BCIS information on individuals who
have earnings recorded under the SSN assigned for non-work purposes
in the form of an electronic data file, the NWALIEN file, 6 to 18
months after the earnings take place.
Our analysis of the file found that for TY 2000, SSA
recorded 872,138 reports of earnings for 574,461 non-citizens who
had been classified as not authorized to work by BCIS. The Agency
also identified $21.3 billion in earnings that were associated with
these SSNs issued for non-work purposes.
We then matched NWALIEN records with SSA's earnings
and employment information and found that:
Employment histories began as long as 38 years ago for some non-work
SSN records.
The average earnings associated with unique non-work SSNs were higher
than the average for full time workers in the U.S. economy.
In an estimated 5,080 instances, earnings were recorded on both
the Master Earnings File and the Earnings Suspense File for different
individuals using the same not-authorized-for-employment SSN, suggesting
possible illegal activity.
Individuals having public responsibilities and positions of trust,
primarily current Federal and active duty military employees, including
SSA employees, are recorded on the unauthorized employment file.
A further review of the records found that some of
these employees are now authorized to work and there was no evidence
that the Agency was notified of the work status change.
SSA needs to obtain timely and accurate information
from BCIS to ensure the validity and usefulness of data recorded
on the NWALIEN file, with an emphasis on BCIS' accuracy of work
status data for each non-work SSN. We also believe that SSA and
BCIS need to establish compatible data fields that will allow the
agencies to effectively match data records.
Specifically we recommended that SSA:
Encourage BCIS to provide the data necessary to identify non-citizens
who are allowed to work.
Match BCIS records to appropriate SSA records, and, where warranted,
remove non-work status from SSA records.
Work with BCIS to determine what information would be most beneficial
to meet organizational goals and how to establish compatibility
between the files.
SSA agreed totally or in part with all three recommendations
and will encourage BCIS to make its records compatible with the
NWALIEN file. The Agency also advised us that once the compatibility
occurs, it will modify its systems to accept BCIS data. In addition,
it will also work with BCIS to determine what information would
be beneficial to meet organizational goals and how to establish
compatibility between files.
