This report presents estimates of the size and characteristics of the resident nonimmigrant population in the United States. The estimates are daily averages for the 12-month period centered on January 1, 2012. In this report, the term resident nonimmigrant refers to foreign nationals who are legally admitted into the United States for specific, temporary purposes and whose classes of admission are associated with residency (e.g., students and temporary workers, as opposed to tourists and business travelers). The characteristics analyzed include category of admission, country of citizenship, age, sex, and destination state. The estimates are derived from U.S. Department of Homeland Security (DHS) administrative records of nonimmigrant arrivals and departures.
