U.S. Citizenship and Immigration Services (USCIS) E-Verify

E-Verify is an Internet-based system operated by U.S. Citizenship and Immigration Services (USCIS). It works within the U.S. Department of Homeland Security (DHS), in partnership with the Social Security Administration (SSA), to provide a means for employers to verify the employment eligibility of newly hired employees. E-Verify compares the information of newly hired employees taken from Form I-9 (the paper-based employment eligibility verification form used for all new hires) against more than 425 million records in SSA’s database and more than 60 million records in DHS’s immigration databases. In 96.1 percent of cases, work eligibility is automatically verified.
