Immigrant: The Immigration and Nationality Act (INA) broadly defines an immigrant as any alien in the United States, except one legally admitted under specific nonimmigrant categories (INA section 101(a)(15)). An illegal alien who entered the United States without inspection, for example, would be strictly defined as an immigrant under the INA but is not a permanent resident alien. Lawful permanent residents are legally accorded the privilege of residing permanently in the United States. They may be issued immigrant visas by the Department of State overseas or adjusted to permanent resident status by the Immigration and Naturalization Service in the United States.

Refugee: Any person who is outside his or her country of nationality who is unable or unwilling to return to that country because of persecution or a well-founded fear of persecution. Persecution or the fear thereof must be based on the alien s race, religion, nationality, membership in a particular social group, or political opinion. People with no nationality must generally be outside their country of last habitual residence to qualify as a refugee. Refugees are subject to ceilings by geographic area set annually by the President in consultation with Congress and are eligible to adjust to lawful permanent resident status after one year of continuous presence in the United States.
