The E-Verify Employment Eligibility Verification Program is an Internet-based system that allows employers to verify the employment authorization status of newly hired and, in the case of federal contractors, existing employees. Jointly administered by the U.S. Citizenship and Immigration Services (USCIS) and the Social Security Administration (SSA), E-Verify compares the data provided on an employee’s Form I-9 Employment Eligibility Verification Form to government records in order to help employers determine if a new hire is eligible to work in the United States. Although the use of E-Verify is not currently mandatory nationwide, numerous states and municipalities have passed legislation requiring its use for some or all employers.

We've developed an interactive map and corresponding chart (pdf) to help employers navigate the patchwork of E-Verify laws across the country.
