Track your N-400 case status
The N-400, Application for Naturalization, is the last step to becoming a U.S. citizen. Between filing and the oath, your case passes through several stages — and USCIS won't notify you as each one changes. TrackPetition watches your N-400 and emails you the moment it moves.
What the N-400 is
The N-400 is filed by a lawful permanent resident who meets the eligibility requirements (residence, physical presence, good moral character). After filing, USCIS reviews the application, schedules a biometrics appointment and an interview with the civics and English tests, then issues a decision and, if approved, schedules the oath ceremony.
Processing time & premium processing
Processing time is driven mostly by your field office and how quickly it schedules the interview and the oath — it can differ a lot between offices. Premium processing is not available for the N-400. Since the interview and the oath are the long poles, watching for those scheduling updates is exactly what tracking gives you.
Processing times change constantly — for the current figure for your specific form and category, check the official USCIS processing-times tool.

Common USCIS statuses
Typical statuses include "Case Was Received", "Interview Was Scheduled", "Request for Additional Evidence Was Sent", "Case Was Approved", and "Oath Ceremony Was Scheduled". USCIS frequently re-words equivalent steps; we normalize those so an interview or oath update reaches you as a real event, not noise.
Why tracking matters
N-400 milestones are time-sensitive — an interview or oath notice you miss can set you back months. Watching the case means the "Interview Was Scheduled" or "Oath Ceremony Was Scheduled" update reaches you the same day USCIS posts it.
Frequently asked questions
- How do I check my N-400 case status?
- Enter your USCIS receipt number in the free check to see the latest status from USCIS, then confirm your email so TrackPetition alerts you when your N-400 moves — including interview and oath updates.
- Will I be alerted when my citizenship interview is scheduled?
- Yes. "Interview Was Scheduled" is a status change, so TrackPetition emails you as soon as USCIS posts it.
- Does TrackPetition tell me when my oath ceremony is set?
- Yes. The oath-ceremony-scheduled update is a status change and triggers an alert like any other movement on the case.
- Is N-400 tracking free?
- The receipt-number check and email alerts are free — best-effort, we try to check about once a day. For reliable, more frequent checks (more than 70 times a week) plus WhatsApp and Telegram, a paid plan is available.
