U.S. Naturalizations

Naturalization confers U.S. citizenship upon foreign nationals who have fulfilled the requirements Congress established in the Immigration and Nationality Act (INA). After naturalization, foreign-born citizens enjoy nearly all of the same benefits, rights, and responsibilities that the Constitution gives to native-born U.S. citizens, including the right to vote.

The Office of Immigration Statistics (OIS) Annual Flow Reports on naturalization contain information obtained from naturalization applications on the number and characteristics of persons aged 18 years and older who became naturalized US citizens during a given fiscal year. Below are the annual flow reports on Naturalization.
