U.S. Citizenship and Naturalization
Naturalization is the process by which a lawful permanent resident becomes a U.S. citizen. Most applicants qualify after five years as a permanent resident, or three years if married to and living with a U.S. citizen. The application is made on Form N-400 and involves a biometrics appointment, an interview covering your application and background, English and civics testing, and finally the oath of allegiance.

The Process
Case preparation
4–6 weeksOnce you engage us, we build your case: we tell you exactly which documents we need, review each one, and assemble the filing package. This stage moves at the pace documents reach us — the sooner we receive what we ask for, the sooner we can file.
Eligibility and history review
2–3 weeksWe confirm your qualifying period, count your absences from the United States against the continuous residence and physical presence rules, and review any criminal, tax, or selective service history that bears on good moral character. This review is the point of the exercise — problems found now can be addressed, whereas problems found at interview rarely can.
File Form N-400
1–2 weeks to fileWe prepare and file the application with USCIS together with the supporting evidence, and file a fee waiver or reduced-fee request where you qualify for one.
Biometrics appointment
1–2 months after filingUSCIS takes your fingerprints and photograph for the background check. In some cases USCIS reuses previously captured biometrics and waives the appointment.
Interview and testing
6–12 months after filingA USCIS officer reviews your application under oath and administers the English and civics tests. We prepare you for both the testing and the questions about your application and travel history.
Oath of allegiance
2 weeks to 3 months after approvalOnce approved you attend a ceremony and take the oath of allegiance. You become a U.S. citizen at that moment and receive your certificate of naturalization.
