Citizenship application (N-400): document checklist
The N-400 naturalization application is thorough. Most denials come from missing documents or inconsistent history — not from failing the civics test.

Filing the N-400
Filing fee: $760 online (as of 2025), $710 paper. Reduced fees available for low-income applicants (Form I-942).
Include: copy of green card (both sides), 2 passport-style photos, and any name change documents.
The 5-year (or 3-year) history
You'll list every trip outside the U.S. in the last 5 years (3 if married to a citizen) — with exact dates. Use your passport stamps, I-94 records, and airline emails to reconstruct this.
Every address you've lived at for 5 years. Every employer for 5 years. Any arrests, citations, or court appearances — even dismissed ones.
Tax records (bring 5 years)
Federal tax return transcripts for the last 5 years. Get them free from irs.gov/transcript — do not use unofficial copies from TurboTax.
If you owe back taxes, bring proof of a payment plan with the IRS. Unpaid taxes are one of the most common reasons for N-400 denial.
Selective Service (male applicants under 31)
Men who lived in the U.S. between ages 18–26 must show Selective Service registration. Verify at sss.gov.
If you failed to register and you're now 26+, USCIS may still approve you but expects an explanation — bring a written statement.
Applicants who track their travel dates, addresses, and tax records over time breeze through N-400. VaultGuardian keeps them in one timeline you can pull up in minutes.
