About This Form
Form N-400 is used by eligible lawful permanent residents to apply for U.S. citizenship through the naturalization process. This service helps clients organize their immigration history, tax records, travel history, and supporting documents for back-office review.
Form N-400 is filed with USCIS. After filing, USCIS will schedule a biometrics appointment and an interview. The naturalization interview includes a civics test and English language test for most applicants.
