THE COMPLETE NATURALIZATION TIMELINE

Here is exactly what happens after you submit your N-400, step by step. Times vary significantly by USCIS field office — some offices are faster than others.

DAY 1

You Submit Your N-400

You mail your completed N-400 form with supporting documents and the $725 filing fee to the correct USCIS lockbox. Keep a copy of everything you send.

WEEK 1–3

Receipt Notice (Form I-797)

USCIS sends you a receipt notice with your 13-character case number (starts with IOE, MSC, LIN, SRC, EAC, or WAC). Save this — you'll use it to track your case at egov.uscis.gov.

MONTH 1–3

Biometrics Appointment

USCIS sends a biometrics appointment notice. You go to an Application Support Center (ASC) for fingerprinting and a photo. Takes about 30 minutes. Bring your appointment notice and green card.

MONTH 6–18

Interview Notice

USCIS sends your interview notice with the date, time, and location of your citizenship interview. This is when you need to be fully prepared — civics test, English test, and personal questions.

INTERVIEW DAY

Your USCIS Interview

A USCIS officer reviews your application, tests your English, and asks you up to 10 civics questions. You need to answer 6 correctly. Most interviews last 20–45 minutes.

SAME DAY OR WEEKS LATER

Decision

The officer may approve you on the spot. Or they may continue your case (need more documents) or deny it. Most applicants who are prepared get approved at the interview.

WEEKS AFTER APPROVAL

Oath Ceremony — You Become a Citizen

You attend an oath ceremony where you take the Oath of Allegiance and receive your Certificate of Naturalization. You are now a U.S. citizen. You can apply for a U.S. passport immediately.

WHAT CAUSES DELAYS

The biggest factors that slow down your application:

⚠ Incomplete application: Missing documents, unanswered questions, or missing signatures cause immediate delays. USCIS will send a Request for Evidence (RFE) which adds 3–6 months.

⚠ Background check issues: Criminal history, even minor offenses, triggers additional review. Always disclose everything upfront.

⚠ Long trips outside the U.S.: If you took trips over 6 months, USCIS needs to verify your continuous residence, which takes additional time.

⚠ Your field office: Processing times vary dramatically by location. Some offices process in 6 months, others take 18+ months. Check current times at egov.uscis.gov/processing-times.

HOW TO CHECK YOUR CASE STATUS

Use your receipt number (from Form I-797) to check your case status anytime at egov.uscis.gov. You can also sign up for email or text notifications when your case status changes.

💡 TIP: If your case is outside the normal processing time for your field office, you can submit a case inquiry at egov.uscis.gov. Wait until your case is at least 30 days past the published processing time before inquiring.

CAN YOU SPEED UP THE PROCESS?

In most cases, no — USCIS does not accept expedite requests for N-400 applications the way it does for some other forms. However, you can avoid delays by:

1. Filing a complete, error-free application the first time. 2. Responding immediately to any USCIS requests. 3. Notifying USCIS of any address changes within 10 days. 4. Using USCIS online filing which is generally faster than paper filing.
