The Step-by-Step Process
Follow these steps in order. Each one builds on the last — don't skip ahead.
Make Sure You're Eligible First
Before doing anything else, confirm you meet the basic requirements. Most people apply through the 5-year Green Card path.
- Lawful Permanent Resident (Green Card) for at least 5 years — or 3 years if married to a U.S. citizen
- Physically present in the U.S. for at least 30 months of those 5 years
- Lived in your current state or USCIS district for at least 3 months
- You are 18 years or older
- Good moral character — no serious criminal history
- Can read, write, and speak basic English (age/disability exceptions exist)
- Willing to take the Oath of Allegiance
Gather Your Documents Required
Get these together before filling out your application. It's much easier to gather docs first.
- Green Card — front and back copy
- Passport(s) — all pages with travel stamps for the last 5 years
- Tax returns for the last 5 years (IRS transcripts are free and easier)
- Any court records if you've ever been arrested or cited — even minor
- Marriage certificate if applying on the 3-year spouse path
- Name change documents if your legal name has ever changed
- Two passport-style photos (2"×2", white background)
Complete Form N-400 Required
Form N-400 is the official Application for Naturalization. File online at myaccount.uscis.gov — you get instant confirmation. Note: if requesting a fee waiver, you must file by paper.
- Create a free account at myaccount.uscis.gov
- Answer every question honestly and completely
- Double-check every date and name spelling before submitting
- Pay the $760 fee online (credit/debit card or bank transfer)
- Can't afford it? Apply for a fee waiver using Form I-912
Biometrics Appointment Required
USCIS will mail you an appointment to have your fingerprints, photo, and signature collected at a local Application Support Center (ASC).
- Bring your appointment notice AND a government photo ID
- Usually scheduled 2–4 months after filing
- Need to reschedule? Call 1-800-375-5283 right away
- Missing without rescheduling can delay your entire case
Study for the Civics Test Don't Skip
Important update (Oct 2025): If you file N-400 on or after October 20, 2025, you take the new 2025 civics test — 20 questions from 128, need 12 correct. Filed earlier? The 2008 test applies: 10 questions from 100, need 6 correct.
- USCIS provides all civics questions for free — study them all
- You'll also read one sentence and write one sentence in English
- Download the free USCIS Civics Practice app on iOS or Android
- Many local libraries and nonprofits offer free citizenship prep classes
- If you're 65+ with 20+ years as a Green Card holder, only 20 questions apply
Attend Your Interview Required
A USCIS officer reviews your application, tests your English, asks civics questions, and verifies your info in person.
- Bring your interview notice, Green Card, passport(s), and any supporting docs
- Officer will go through your N-400 line by line — know your application cold
- Answer clearly. Say "I don't understand" if confused — never guess
- Fail the civics test? You get one more chance within 60–90 days
- Need a translator? Call USCIS in advance to arrange one
Receive Your Decision Almost There
After your interview, USCIS will approve, continue, or deny your application.
- Granted same day (most common!) — Oath Ceremony is scheduled right away
- Continued — USCIS needs more info; respond to any requests quickly
- Denied — You have the right to appeal; contact an immigration attorney immediately
Take the Oath of Allegiance 🇺🇸 Final Step!
At the naturalization ceremony you'll take the Oath of Allegiance and receive your Certificate of Naturalization. You are officially a U.S. citizen!
- Bring your Green Card — you turn it in at the ceremony
- Bring the ceremony notice and a photo ID
- Receive your Certificate of Naturalization — store it safely, it's irreplaceable
- After the oath, apply for your U.S. passport, register to vote, and update Social Security
Insider Tips: Cut Through the Red Tape
From people who've been through the process.
Track Everything Online
Create your USCIS account the day you apply. Turn on notifications. Check it weekly. This is your single source of truth for appointments and case updates.
Keep a Master Folder
Keep digital and physical copies of every document you submit. If USCIS says something is missing, you'll have proof you sent it.
Watch Your Travel
Don't leave the U.S. for more than 6 months at a stretch. Trips over 180 days can reset your continuous residence clock. Log every trip with exact dates.
Free Legal Help Exists
USCIS maintains a list of free and low-cost legal aid providers. Accredited DOJ representatives at nonprofits can help just like attorneys — at no cost.
Community Orgs Help
Many ethnic community centers, libraries, and nonprofits offer free citizenship prep classes and legal advice nights. Search "citizenship class near me."
Use Your Congressional Rep
If your case is stalled beyond normal processing times, your U.S. Representative can make a free congressional inquiry on your behalf — often very effective.
Check Processing Times First
USCIS publishes live processing times by field office. Check uscis.gov/tools/processing-times before applying — times vary from 8 to 24 months by location.
Keep Your Taxes Clean
Make sure all tax returns are filed before applying. USCIS will ask about taxes on your N-400. Unfiled returns are a red flag that can seriously complicate your case.
