When you begin a new job in the United States, you are required to provide both proof of identity and employment eligibility. To do this, your employer will have you fill out an Employment Eligibility Verification form (I-9 form) and you will have to present acceptable documentation. The U.S. Citizenship and Immigration Services provide three lists naming the documents that are accepted. List A contains documents that establish both identity and employment authorization, therefore one document from this list will satisfy both requirements. If you do not have a document from List A available, then you have the option to present a combination of one document from List B and one document from List C. List B contains documents that establish identity while List C contains documents that establish employment authorization. In addition, unless it is a certified copy of a birth certificate, all documentation presented must be the original copy. Photocopies are not accepted.
So when you start that new job, don’t forget your documentation.
Here are the lists of acceptable documentation as provided by the USCIS: http://www.uscis.gov/files/form/i-9.pdf
