In the United States, employers are required by the United States Citizenship and Immigration Services (USCIS) to complete the Employment Eligibility Verification Form, Form I-9, for all new employees, for citizens or noncitizens alike. The Form I-9 requires that the employer examine the identity documents and work authorizations for each employee. Instead of filing this information with USCIS, the employer is required to keep this document on file and present for inspection upon request of an authorized agent of the government. Employers are required to retain the Form I-9 for three years from the date of hire of the employee or from one year following the employee's termination, whichever is later. Documents presented by employees must verify both identity and the worker's right to engage in permanent employment in the United States. The Form I-9 is supplemented by a sheet detailing which documents are acceptable for verification of these parameters. While there is a Spanish version of the form, the USCIS only considers the Spanish translation only valid for employers located in Puerto Rico. In all other U.S. States and Territories, employers must use the English version of Form I-9.
