Track your N-400 naturalization application by using the receipt number USCIS mails you after filing to check your case at egov.uscis.gov, free of charge. If you filed on paper, USCIS will send you instructions to create an online account; if you filed online, you already have one. Both the receipt number portal and your online account show you your case status, the notices USCIS sends you, and what happens next—without needing to call or visit an office.
The N-400 process has several stages with their own notices and timelines. By tracking your case, you'll know when to expect your biometrics appointment, interview, and final decision. USCIS processes thousands of cases, and checking your own status is faster and more reliable than trying to reach an agent.

Using Your Receipt Number and Online Account
Your receipt number is a 13-character code (three letters and ten numbers) that appears on every USCIS notice you receive after filing. Go to egov.uscis.gov, enter your receipt number and date of birth, and you'll see your current case status instantly. This free tool works 24/7 and requires no password or account login.
If you filed Form N-400 on paper, USCIS will mail you an Account Acceptance Notice with instructions to create a free online account. If you filed online, you already have an account. An online account is more helpful than the receipt number lookup alone: it shows your full case history, sends you automatic email or text updates, and displays up to five recent actions on your case. Log in whenever you want to confirm that USCIS received a notice or to see if a new stage has started.
What to Expect at Each Stage
After USCIS accepts your N-400, it will send you a biometrics appointment notice (Form I-797C) with the date, time, and location of your Application Support Center visit. Biometrics appointments are required unless USCIS waives them—you'll know from your notice.
This is one of the first notices you'll receive and appears in your online account. Once biometrics and background checks are complete, you'll receive an interview notice telling you the date, time, and location of your naturalization interview. You must appear at that USCIS office on the scheduled day. If you do not pass the English or civics test at your interview, USCIS will send you a retest notice scheduling the failed portion for 60 to 90 days later.
How Long Does the Process Take?
USCIS must issue a decision within 120 days of your initial naturalization interview. If no decision arrives within that window, you may pursue judicial review in district court. However, processing times vary significantly by field office; USCIS publishes current times on egov.uscis.gov/processing-times based on how long it took to complete 80% of cases in the last six months at your specific location.
Check the processing times for your field office before filing if you want a rough estimate. Actual times can be faster or slower than posted, and delays can happen at any stage—biometrics scheduling, background checks, interview assignment, or final decision. Your online account will show if your case is taking longer than typical.
Getting Help If Your Case Stalls
If you cannot reschedule appointments online or have questions about your case status, contact the USCIS Contact Center toll-free at 800-375-5283 (TTY 800-767-1833), available Monday to Friday, 8 a.m. to 8 p.m. Eastern time. Have your receipt number ready when you call. The Contact Center can answer questions about delays, help you update your contact information, and explain what your notice means.
If you move during your N-400 process, update your address in your online account so USCIS can mail notices to the correct location. If a notice is lost or unclear, the Contact Center can send you a copy or explain what happens next.
