All U.S. employers must properly complete Form I-9 for each individual they hire for employment in the United States. Both employees and employers (or authorized representatives of the employer) must complete the form. Form I-9 is an essential document for employers to confirm that employees are legally eligible to work in the United States. The form requires employees to present original and unexpired documents establishing their identity and employment authorization. Employers must review these documents to determine their authenticity and record the necessary information on the I-9 form.


The federal government has established two distinct systems, Form I-9 and E-Verify, to verify the eligibility of newly hired employees. While both serve the purpose of confirming an individual’s work authorization, they differ in their processes and requirements.

Form I-9, Employment Eligibility Verification, is the key element of E-Verify’s web-based employment eligibility verification. E-Verify electronically compares information the employer enters from Form I-9 to records available to the Social Security Administration and the U.S. Department of Homeland Security. E-Verify protects jobs for authorized workers and helps employers maintain a legal workforce.  

Participation in E-Verify is voluntary for most employers, other employers may be required by State law or Federal regulation to use E-Verify.

  • States that require all or most employers to use E-Verify are Alabama, Arizona, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, and Utah.
  • Public employers and/or contractors with the state: Florida, Indiana, Missouri, Nebraska, Oklahoma, Pennsylvania, and Texas.
  • Public employers only in Idaho and Virginia.
