I-9 Verification is a mandatory process required by U.S. Citizenship and Immigration Services (USCIS) that ensures employers verify the identity and employment authorization of all new hires, including both U.S. citizens and noncitizens. Using Form I-9, employers must review acceptable documentation and complete verification within specific timelines after an employee’s start date.

I-9 verification is often bundled with background checks as part of a broader, compliant hiring workflow. When managed digitally, the process can reduce errors, improve recordkeeping, and help organizations stay audit-ready. Proper I-9 compliance is a critical component of comprehensive candidate screening and risk management.
