USCIS Updates E-Verify Accuracy Statistics

On July 18, 2013, the U.S. Citizenship and Immigration Services (USCIS) released a new E-Verify program evaluation from its external evaluator, Westat. The new report contains two measures of E-Verify’s accuracy: a new measure called the final non-confirmation (FNC) accuracy rate and an existing measure called the erroneous tentative non-confirmation rate (TNC).

To check an employee’s work-authorization status, E-Verify compares data from form I-9 to Social Security Administration (SSA) and Department of Homeland Security (DHS) databases. Employers electronically submit the employee’s Social Security Number (SSN), name, date of birth, citizenship or immigration status, and if applicable, alien number (Anumber) or I-94 number. Workers who initially appear unauthorized receive a TNC, which they may appeal. If the appeal is rejected, or no appeal is filed, the worker receives an FNC. In FY2012, nearly 99 percent of those checked through the system were immediately confirmed.
