The Employment Eligibility Verification, or Form I9, is a form from the United States Citizenship and Immigration Services. As required by the Immigration Reform and Control Act of 1986, it checks the identity and legal right to work of all paid U.S. workers. Every U.S. employer must ensure that Form I-9 is filled out correctly by every person they hire to work in the U.S. My authorized representative I-9 form verification service can be done with either a hard copy or a digital copy.
