The U.S. Citizenship and Immigration Services (USCIS) has incorporated the Department of State’s (DOS) passport data into the E-Verify program. The enhancement was added to reduce the incidences of mismatches among foreign born citizens. A previously conducted evaluation by the USCIS revealed that foreign-born citizens were more likely to receive mismatches, known as Tentative Non-confirmations (TNCs), than U.S.-born citizens. The USCIS states that passport number checking capability for citizens providing a U.S. passport as Form I-9, Employment Eligibility Verification, identification improves the program. If the Department of Homeland Security (DHS) or the Social Security Administration (SSA) is unable to immediately confirm a U.S. citizen’s work eligibility, USCIS can now check DOS records prior to issuing a TNC. If citizenship information provided on the Form I-9 matches those records, E-Verify will confirm the individual’s work authorization. Without the enhancement, the system would have issued a TNC, prompting a potentially “authorizedEworker to resolve the mismatch issue. In addition, foreign-born U.S. citizens who ultimately receive TNCs may now call the USCIS directly rather than visiting an SSA office to resolve their cases.
