Answer:
Naturalization is the legal process through which a foreign citizen or national can become a U.S. citizen. In order to be naturalized, an applicant must first meet certain criteria to apply for citizenship. Then, the applicant must complete an application, attend an interview, and pass an English and a civics test. Upon successful completion of these steps, the applicant takes an oath of allegiance, and becomes a citizen.
These legal requirements help the immigration service ensure that only those people who are sincere in their desire to become U.S. citizens become naturalized. Below you'll find a more detailed look at the basics of naturalization, including eligibility for naturalization and the steps involved in the application process.
