Form I‑9, Employment Eligibility Verification, is a mandatory U.S. Department of Homeland Security form that employers must complete to verify the identity and work authorization of every individual hired in the United States. All employers—regardless of size—must ensure that employees present acceptable identity and employment authorization documents, and employers must review, record, and retain the form according to federal requirements.
The I‑9 process is governed by U.S. Citizenship and Immigration Services (USCIS) and includes strict rules for document inspection, anti‑discrimination protections, remote verification procedures, and record retention. Failure to properly complete or maintain Form I‑9 can result in civil fines, penalties, and compliance audits.
