As of Oct. 1, 2008, the U.S. Citizenship and Immigration Services (USCIS) redesigned the citizenship test for immigrants who want to become naturalized Americans.
The reason for redesigning the test was to create "a more standardized, fair, and meaningful naturalization process." The newly revised test contains questions on the core concepts of American democracy, the rights and responsibilities of citizenship, reading and writing proficiency, and an additional 100 history and government questions.
