The U.S. Citizenship and Immigration Service (C.I.S.), formerly known as the U.S. Immigration and Naturalization Service (I.N.S.), requires employers to complete Form I-9 for each individual they hire for employment within three working days of the new employee’s employment. On the form, the employer must verify the individual’s employment eligibility by identifying documents presented by the employee and recording the document information on the Form I-9. Acceptable documents for this purpose are listed on the back of the Form I-9 and at the end of this article. (See Tables A-C for a listing of these documents.)
