An immigrant is a person who lives in a country other than the one they were born in. This includes people who have taken the citizenship of the destination country, served in its military, married a native, or have another status. The term "immigrant" is not used universally, and other terms frequently used include "international migrant," "foreign born," and "migrant". National statistical agencies base their counts of migrant populations on the number of people who say they were born in another country and/or who hold the citizenship of another country. In casual usage, "immigrant" can refer to any foreign-born person, but in the United States, some are technically considered "nonimmigrants". While immigrants intend to stay in a new country permanently, nonimmigrants remain only temporarily, whether thats for a few days on a business trip, a few months as a seasonal worker, or a few years as a student. Those considered immigrants also include a range of people with different legal statuses.
