The U.S. Citizenship and Immigration Services (USCIS) has published a revised version of Form I-9, Employment Eligibility Verification. By January 22, 2017, all employers must begin using the new I-9 Form for verification of employment.

Under the Immigration Reform and Control Act (IRCA), employers are prohibited from hiring employees in the United States without verifying their identity and employment authorization on Form I-9. Technical changes were made to the form, which are designed to reduce errors and enhance form completion.
