About this template
Naturalisation through Form N-400 is the standard path to U.S. citizenship for lawful permanent residents (LPRs). The general eligibility requires: (1) at least 5 years as an LPR (3 years if married to and living with a U.S. citizen, special rules for military), (2) continuous residence in the U.S. for that period, (3) physical presence for at least half of the qualifying period (typically 30 months out of 60 for the 5-year rule), (4) residence in the state of filing for at least 3 months, (5) good moral character during the statutory period and continuing to oath, (6) ability to read, write, and speak basic English (with age/disability waivers), (7) knowledge of U.S. history and government (tested via civics test, with age/disability waivers), and (8) attachment to the principles of the U.S. Constitution. The current N-400 fee is $710 paper / $760 online (verify current at uscis.gov; fee waivers available via Form I-912 for low-income applicants). Processing times average 6-12 months; biometrics appointment within 1-2 months of filing, interview 6-10 months in, oath ceremony 1-3 months after approval. The biggest pre-filing checks: physical-presence count (use trip-by-trip records — passport stamps, I-94 records), tax compliance (file all required returns; no outstanding balances), Selective Service registration for males 18-25 during the period, and any criminal-record items (even minor ones can affect good moral character; bring certified dispositions). The N-400 has expanded substantially in recent years and now collects detailed information on travel, employment, and prior immigration history; complete it carefully — discrepancies with prior filings can trigger fraud findings.
When to use it
- 5 years as a green card holder (general rule).
- 3 years married to a U.S. citizen (continuous marriage required).
- Military service (1 year peacetime, immediate during wartime).
- Renewing an old green card AND naturalising — file N-400 instead of I-90.
- Children acquiring through citizenship parent (different forms — see N-600).
What to include
- Applicant identification with A-Number.
- Eligibility basis (5-year, 3-year-USC-spouse, military).
- Key dates: LPR admission, physical-presence count.
- Continuous-residence confirmation.
- Good moral character statement.
- English and civics readiness or accommodations.
- Enclosed documents checklist.
