In compliance with the Bureau of Citizen and Immigration Services regulations, an employer may only hire persons who may legally work: citizens and nationals of the United States and aliens authorized to work.  Every time a person is hired to perform labor or services in return for wages or other remuneration, the employer must verify the individual's identity and employment eligibility, complete and retain a Form I-9, and be able to make the Form I-9 available for inspection.  This form is available from Student Employment Services, Human Resource Services and the USCIS website.

Employees must present to the employer an original document or documents that establish identity and employment eligibility. For convenience, on the back of the Form I-9 are the Lists of Acceptable Documents. Some documents establish both identity and employment eligibility (from List A), other documents establish identity only (from List B) or employment only (from List C). Employees can choose which document(s) they want to present from the Lists of Acceptable Documents -- either one document from List A, or a combination of documents (one from List B and one from List C). The employee must complete Section 1 of the form when work begins. The employer must review the employee's documents and fully complete Section 2 of the form within 3 business days of the hire.
