U.S. Citizenship and Immigration Services Form I-551 is a permanent resident card, according to the U.S. Department of Homeland Security. Commonly called a green card, it is used as proof of permanent residence.
Permanent resident cards are issued to individuals who have been granted permission to live and work in the United States on a permanent basis, notes the U.S. Department of Homeland Security. The information on the card includes identifying information such as the holder’s name, date of birth, photograph, fingerprint and card number. Additional information includes the alien/USCIS number and expiration date.
There are several ways to become a permanent resident, such as being sponsored by a family member or employer in the United States, through refugee status or on humanitarian grounds, notes U.S. Citizenship and Immigration Services.
