Definition and meaning of naturalized citizen: A naturalized citizen is a person who was not born a U.S. citizen, but legally became a citizen through the naturalization process. Naturalization is a process that involves a formal application, background check, and the passing of an English language and civics test. Once naturalized, a person acquires all the same rights and privileges as a person born in the United States. In addition to giving more rights to those who become naturalized citizens, it also diversifies the political landscape by providing a voice to more independent candidates, who are not tied to the traditional two-party system. Naturalized citizens are able to vote, hold office, and help to shape the future of the United States. They can also petition for family members to become citizens, which is an invaluable contribution to the fabric of the American society.
