What is Lawful Permanent Resident (LPR)?
Lawful Permanent Resident (LPR) meaning A person who has immigrated legally, admitted to the United States by DHS as a permanent resident of the United States and has a Permanent Resident Card, Form I-551 (formerly called Alien Registration Card, also known as green card). Form I-551 is a wallet-sized card showing that the person is a lawful permanent resident (immigrant) in the United States. Permanent resident status is not the same as being a U.S. citizen. However, you have authority to live and work in the United States permanently, as well as other rights and responsibilities. Learn more about Lawful Permanent Residents, including how to replace or renew a Permanent Resident Card, on the USCIS Website. Learn about requirements for entry into the United States on the CBP website. This person may also be called a legal permanent resident, a green card holder, a permanent resident alien, a legal permanent resident alien (LPRA) and resident alien permit holder.
