Form N-400 (Naturalization Application)

Form N-400 is an application filed by a lawful permanent resident who meets certain eligibility requirements and seeks to become a U.S. citizen through the naturalization process. The form requires the applicant to provide personal information, demonstrate their physical presence and continuous residence in the United States, and attest to their good moral character and attachment to the principles of the U.S. Constitution. Form N-400 is adjudicated by USCIS and typically requires an interview and civics test to assess the applicant’s knowledge of English and U.S. history and government.
