On the I-9 form, verify that you have seen documents establishing identity and work authorization for all your new employees U.S. citizens and noncitizens alike hired after November 6, 1986. Remember that many work authorization documents must be renewed on or before their expiration date, and the I-9 form must be updated. This process is called reverification. At this time, you must accept any valid documents your employee chooses to present, whether or not they are the same documents provided initially. Be aware that U.S. citizenship, or nationality, belongs not only to persons born in the United States but also to all individuals born to a U.S. citizen, and those born in Puerto Rico, Guam, the Virgin Islands, the Commonwealth of Northern Mariana Islands, American Samoa, and Swains Island.
Citizenship is granted to legal immigrants after they complete the naturalization process.
