The I-9 form is an employment eligibility verification document that all employers in the U.S. must complete and retain for every employee they hired after Nov. 6, 1986. On the form, an employee must attest to their legal employment authorization and must present acceptable documents that confirm their identity and employment authorization.
Employers must retain an employee’s I-9 for three years after the date they are hired, or for one year after the employee leaves employment, whichever is later. The forms must also be made available for inspection if requested by authorized U.S. government officials.
