Persons Naturalized by Country of Birth and Core-Based Statistical Area (CBSA) of Residence

This form reports the number of persons naturalized by country of birth and Core Based Statistical Area (CBSA) of residence by federal fiscal year (Oct. 1-Sept. 30). Naturalization is the process by which U.S. citizenship is conferred upon foreign citizens or nationals after fulfilling the requirements established by Congress in the Immigration and Nationality Act (INA). After naturalization, foreign-born citizens enjoy nearly all the same benefits, rights and responsibilities that the Constitution gives to native-born U.S. citizens, including the right to vote. Naturalizations refer to persons aged 18 and over who become citizens of the United States. Most legal permanent residents are eligible to apply for naturalization within five years after obtaining legal permanent resident status.

The source for these data is the administrative records of U.S. Citizenship and Immigration Services (USCIS) of the Department of Homeland Security. These records consist of information from applications for naturalization.
