Immigrant is a person who immigrates or moves to a new country. An international student is not classified as immigrant.
More illegal immigrants are entering the United States than legal immigrants, a study found. The report, by the Pew Hispanic Center, a nonpartisan research group, also found that the number of immigrants coming to the United States legal and illegal grew rapidly starting in the mid-1990s, hit a peak at the end of the decade and then declined after 2001. 
Over time, millions around the world have found emigrating to the U.S. as the only alternative to starvation, death, or a life full of hardship and suffering. With thousands from nations spanning the globe, America has become a mosaic of people, culture, and hope.
