The U.S. Citizenship and Immigration Services Form I-9, Employment Verification, is used to verify the identity and employment eligibility of new hires, according to the U.S. Citizenship and Immigration Services. The completion of Form I-9 is required for every citizen and noncitizen hired in the United States.
Employers and new employees are both required to complete the Form I-9, explains the U.S. Citizenship and Immigration Services. The employee must present acceptable identification documents to the employer who must then review the documents for authenticity.
Employers are not to submit Form I-9, advises the U.S. Citizenship and Immigration Services. Instead, employers must retain a completed copy of the form for at least the first three years after the employee's hire date or for one year after employment is terminated.
