There are four categories in which people living in the United States can fall on.
They are:
citizens- which were either born in the U.S. or have been living there for 3-5 years as permanent residents,
permanent/conditional residents- are the ones who have a green card or residents who have been married for less than two years before getting the green card,
non-immigrant- people who live in the U.S. temporarily such as F1, B1/B2 and K1 Visa holders and
undocumented- people who live in the U.S. without permission.
