There are two ways to become a United States citizen, including birth and naturalization, although foreign citizens immigrating to America must complete the requirements set by Congress in the Immigrants and Nationality Act, explains the Department of Homeland Security. To become United States citizens, applicants must fulfill the naturalization requirements.
Any potential citizen must be 18 years of age or older, live in the United States for at least five years, be a green card holder for five years, have a good moral character and be able to read, write and speak English, states U.S. Citizenship and Immigration Services. To start the process, applicants must also file form N-400.
The naturalization process includes an interview with a United States Citizenship and Immigration Service agent who is provided to determine the applicant’s ability to speak, read and write English. The civics portion of the interview involves questions pertaining to the United States’ government and history. The applicant must answer 60 percent of the questions correctly to pass the assessment. The application process gives two chances to pass the assessment, and if the applicant fails any portion of the assessment, that person is scheduled to take that portion again within 90 days. The USCIS offers resources on how to become a United States citizen on its website, including study materials for the English and civics tests.
