Note that often the terms immigration, immigrants, migration and migrants are used interchangeably. When doing research remember that immigration refers to a movement between nations whereas migration is a movement within a nation. For the U.S. experience, immigrants are often also part of migrant populations (which are often referred to as seasonal laborers). International immigrants face legal/judicial issues as temporary immigrants with special visas or no visas (often referred to as illegal aliens or undocumented aliens).
