What term is used for a person who emigrates to a foreign country with an immigrant visa?

The term for a person who emigrates to a foreign country with an immigrant visa is "immigrant." An immigrant is someone who has moved from their home country to another country for various reasons, such as better economic opportunities, family reunification, or quality of life. An immigrant visa specifically permits entry and residence in the new country, which distinguishes the status of the individual as a legal resident or future citizen.

While "expatriate" usually refers to someone who lives outside their native country but does not necessarily imply a change of nationality, "emigrant" describes a person who leaves their home country to settle elsewhere, but doesn't specify the legal status in the new country. "Refugee" pertains to individuals fleeing from persecution or danger in their home country, which does not align with the conditions stated in the question regarding an immigrant visa. Understanding these terms helps clarify the different statuses individuals hold when moving between countries.
