Lawful permanent residence status authorizes a foreign national to live and work lawfully within the United States, but a lawful permanent resident cannot vote in U.S. elections, travel outside the U.S. for an extended period of time, and cannot reside outside the United States. A lawful permanent resident’s status can be canceled if the person commits certain crime. In contrast, U.S. citizenship authorizes a person to vote, travel for extended periods of time outside the United States and reside in another country. A U.S. citizen will remain so for his or her life.
