In order to reduce mismatch rates for naturalized citizens, U.S. Citizenship and Immigration Services has incorporated improvements in its E-Verify Program. The program is a web-based system allowing participating employers to electronically verify the employment eligibility of newly-hired workers. The program occasionally produced mismatches between social security numbers and names, leading to potential termination of legally authorized workers.

According to USCIS, naturalized citizens who have not yet updated their records with the Social Security Administration are the largest category of work-authorized persons who initially face an SSA mismatch in E-Verify. The system will now include naturalization data to help instantly confirm the citizenship status of naturalized U.S. citizens. The agency also plans to initiate citizenship status records information sharing with SSA, and to check State Dept. passport records to further reduce mismatches and tentative nonconfirmations in employment eligibility.
