Statutes and Regulations

Form I-9 Federal Statutes and Regulations

Form I-9, Employment Eligibility Verification, requirements come out of the Immigration Reform and Control Act of 1986 (IRCA). IRCA prohibits employers from hiring and employing an individual for employment in the U.S. knowing that the individual is not authorized with respect to such employment. Employers also are prohibited from continuing to employ an individual knowing that he or she is unauthorized for employment. This law also prohibits employers from hiring any individual, including a U.S. citizen, for employment in the U.S. without verifying his or her identity and employment authorization on Form I-9.

It is MANDATORY in 20 States. South Carolina is one of them.
