Non-citizen: Any person in the U.S. who is not a U.S. citizen, even if that person has legal immigration documents.
Undocumented: Non-citizens who entered the U.S. illegally or have legal immigration documents that have expired. Expired means they are too old and can not be used any more.
Lawful Permanent Resident or LPR: Non-citizens who have permission from the government to make the U.S. their permanent home. This is the most secure immigration status. It is sometimes called having a “green card.”
U.S. Citizens: Anyone who was born in the U.S., its territories, and certain possessions, such as Puerto Rico. This includes children born to undocumented parents.
Some immigrants become U.S. citizens through a process called naturalization (nach-er-uh-li-ZAY-shun).
