Lawful permanent resident status permits a foreign national to live and work in the United States indefinitely. An “LPR” is issued a Form I-551 Permanent Resident Card as evidence of his or her immigrant status in the United States. Once upon a time, the card was indeed the color green, and to this day, it is colloquially referred to as a “green card.”
The process to become an LPR is complex, generally involving a petition by a family member or a prospective employer, and requires an understanding of applicable law and procedures.
