Before you submit your N-400, gather every document on this list. USCIS will review these at your interview. Missing documents don't just delay your application — they can trigger a request for evidence (RFE) that adds months to your wait time.
💡 IMPORTANT: Always send copies — never originals — unless USCIS specifically requests them. Keep all originals in a safe place at home.
REQUIRED FOR ALL APPLICANTS
01
Permanent Resident Card (Green Card)
WHERE TO GET IT: Your physical card. Make front and back copies.
WHY USCIS NEEDS IT: Proves your immigration status and when you became a permanent resident. This is the most important document.
02
Passport(s) from Your Birth Country
WHERE TO GET IT: Your current and any expired passports from the past 5 years. Contact your home country's embassy if you need a replacement.
WHY USCIS NEEDS IT: Confirms your identity, nationality, and travel history. The passport stamps show every time you left the U.S.
03
Federal Tax Returns — Last 5 Years
WHERE TO GET IT: Download from IRS.gov (Get Transcript), or ask your tax preparer. You need Form 1040 for each year.
WHY USCIS NEEDS IT: Proves continuous U.S. residence and that you filed taxes as required. Missing tax returns are a red flag.
04
Travel Records — All Trips Outside the U.S.
WHERE TO GET IT: Review your passport stamps. Create a list with: destination, departure date, return date, total days outside U.S.
WHY USCIS NEEDS IT: Documents your continuous residence. Trips over 6 months can affect your eligibility. Be thorough — include even short weekend trips.
05
Two Passport-Style Photos
WHERE TO GET IT: Any post office, CVS, Walgreens, or FedEx. Must be taken within the last 30 days. Cost: $10–15.
WHY USCIS NEEDS IT: Required for your naturalization certificate. Specific size and format requirements — ask the photographer for "USCIS passport photos."
06
Filing Fee — $725
WHERE TO GET IT: Pay by check, money order, or online at USCIS.gov. Made payable to "U.S. Department of Homeland Security."
WHY USCIS NEEDS IT: Covers the $640 application fee + $85 biometrics fee. Fee waivers available if you qualify based on income.
IF MARRIED TO A U.S. CITIZEN (3-Year Rule)
07
Marriage Certificate
WHERE TO GET IT: Vital records office in the county/country where you married. Allow 2–4 weeks for delivery.
WHY USCIS NEEDS IT: Proves your marriage to a U.S. citizen, which qualifies you for the 3-year residency rule instead of 5 years.
08
Proof of Spouse's U.S. Citizenship
WHERE TO GET IT: Copy of spouse's U.S. passport, birth certificate, or naturalization certificate.
WHY USCIS NEEDS IT: Confirms your spouse is actually a U.S. citizen, not just a permanent resident.
09
Proof You Live Together
WHERE TO GET IT: Joint bank statements, joint lease or mortgage, joint utility bills, or joint tax returns showing same address.
WHY USCIS NEEDS IT: Confirms you are in a bona fide marriage living together, not just legally married on paper.
IF PREVIOUSLY MARRIED
10
Divorce Decree or Death Certificate
WHERE TO GET IT: Court records where the divorce was finalized, or vital records for death certificate.
WHY USCIS NEEDS IT: Every prior marriage must be accounted for. USCIS needs to see how each previous marriage ended.
IF YOU HAVE CRIMINAL HISTORY
⚠ CRITICAL: If you have any arrests, citations, or criminal charges — even minor ones, even if charges were dropped — you must disclose them. USCIS will find them. Hiding past legal issues is grounds for denial and can affect future applications.
11
Court Disposition Records
WHERE TO GET IT: The court where your case was heard. Request "certified disposition records."
WHY USCIS NEEDS IT: Shows the outcome of any arrest or charge. Even if charges were dismissed, you need the paperwork showing that.
IF YOU SERVED IN THE U.S. MILITARY
12
DD-214 (Certificate of Release or Discharge)
WHERE TO GET IT: Request at archives.gov/veterans. Allow 3–6 months. Military service may qualify you for expedited naturalization.
WHY USCIS NEEDS IT: Verifies honorable service. Veterans may qualify for naturalization without the residency requirement.
DOCUMENT ORGANIZATION TIPS
Use a binder with labeled tabs. Organize documents in the same order as your N-400 sections. This makes the interview much smoother.
Make 3 copies of everything. One set for USCIS, one for your records, one as backup. Never submit originals unless required.
Get translations certified. Any document not in English must have a certified translation. A bilingual family member is NOT sufficient — use a professional translator.
⚠ Don't wait until the last minute. Some documents like IRS transcripts and court records can take 2–8 weeks to arrive. Start gathering now, even if your application is weeks away.
