How does SSA verify that a nonimmigrant legally entered the United States?
SSA uses the DHS Systematic Alien Verification for Entitlements (SAVE) Programs Verification Information System (VIS) as its primary data source to verify legal entry into the United States and, in conjunction with travel documentation, to verify the immigration status of non-citizen SSN applicants. It may take several days after arrival of a nonimmigrant for data about the arrival to be uploaded to VIS. To provide a secondary data source, the Student and Exchange Visitor Program (SEVP), along with the SAVE Program, developed a method for SSA officials to indirectly access SEVIS data for comparison. SEVIS offers alternate data verification for F/M/J nonimmigrants and more rapid updates. Since this alternate approach was introduced in early 2004, the immigration status of nearly 125,000 F/M/J SSN applicants has been verified using SEVIS.
