The federal government requires employers to verify the identity and employment authorization of individuals hired for employment in the United States. As of January 22, 2017, all employers must use the new I-9 Forms released by the United States Citizenship and Immigration Services (USCIS) for new hires. Use of any prior versions of the form will be considered invalid.
Links to certain versions of the form and form instructions are provided below.
The new form does not need to be used for existing employees except when re-verifying an employee because his or her work authorization is expiring and an outdated version of the I-9 was used at the time of hire, or if you discover on or after January 22, 2017, that an I-9 was never completed or it is missing for an employee.
