After USCIS reviews the application form and any supporting information, the agency then schedules an interview. The interview acts as a test to determine whether the applicant has a working knowledge of the English language.
During the interview, the agent asks questions about U.S. civics, and applicants must answer 60 percent of the questions correctly to pass. Therefore, the Wheaton application process for citizenship includes an oral test as one of the required elements. An applicant must also be able to write sentences in English.
