United States lawful permanent residency is the immigration status of a person authorized to live and work in the United States of America permanently.

Commonly known as a green card because of its color, it serves as proof that its holder, a lawful permanent resident (LPR), has been officially granted immigration benefits, including permission to reside and work in the United States. This status stands to be removed if some conditions are not met.

Adult permanent residents of the United States (18 years of age or older) are required to carry their actual green card at all times.

Green cards are valid for 10 years for permanent residents, and 2 years for conditional permanent residents. After this period, the card must be renewed or replaced.
