In addition to flow reports which analyze populations changing status due to administrative immigration events such as naturalizations or grants of lawful permanent residence, the Office of Immigration Statistics occasionally publishes population estimates of a particular subgroup. Population estimates take information on immigration flows and may combine it with other counts or estimates, such as those in the U.S. Census Bureau’s American Community Survey (ACS), as well as demographic life expectancy tables to give an idea of population size and characteristics in a given year. Terminology, data sources, and methodology may have shifted over time. Current series include population estimates for unauthorized immigrants, nonimmigrant residents, and lawful permanent residents.

About this Report

The reports below present estimates of the size and characteristics of the resident nonimmigrant population in the United States. 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.
