A Permanent Resident Card for the USA, also known as a green card is an identification card for permanent resident status of an alien in the United States of America. A green card also refers to an immigration process of becoming a permanent resident.

Adjustment of status is a procedure that permits an eligible person to become a lawful permanent resident without having to leave the United States. Applicants that have come to the U.S. by a K1 fiancée visa or K3 spousal visa must file for an adjustment of status.

A U.S. permanent resident always keeps the green card in his/her possession at all times. The resident must have a current valid green card available at all times to show to the USCIS officer, when asked.
