Which of the following terms describes a person permitted to live permanently in the U.S.?

The term "lawful permanent resident" specifically refers to an individual who has been granted permission to live permanently in the United States. This status is conferred through immigration processes, and it allows individuals to reside and work in the U.S. without time restrictions that pertain to temporary statuses. Lawful permanent residents hold "green cards," which serve as proof of their status and provide them with certain rights and responsibilities similar to those of U.S. citizens, though they cannot vote in federal elections.

In contrast, a visitor refers to someone who is in the U.S. temporarily, typically for tourism or business, and does not have the right to stay indefinitely. A temporary resident is another form of limited status, allowing individuals to reside in the U.S. for a designated period but does not provide permanent residency. Lastly, a non-resident alien generally refers to someone who is not a citizen and does not have the right to reside permanently in the U.S., often being categorized by their short-term stay or lack of immigration status. Thus, the correct answer is clearly the one that defines someone with the right to live permanently in the country.
