N-400 case status: Naturalization
An N-400 case timeline can help organize receipt, appointment and decision records. An interview event by itself does not establish that naturalization is complete.
Official sources and what they support
- USCIS — N-400 form and instructions ↗
Official form purpose and current instructions; application-specific decisions must be checked in the relevant notice.
- USCIS — Case Status Online ↗
Official case-status verification for a receipt; not a specification of account JSON or event codes.
- USCIS — Case Processing Times: how to use the information ↗
Processing-time information and how the receipt-date inquiry tool determines when an inquiry is available.
- USCIS — Naturalization: What to expect ↗
Biometrics notices, interview and subsequent naturalization steps; an interview is not the complete process.
Our import steps, field checks and timestamp calculations describe this product. These sources do not certify our software or provide an official mapping of internal account endpoints.
What should I check in my N-400 history?
Confirm the purpose and local time of any appointment from the actual notice. A generic appointment category in the export may not identify an interview or another type of appointment.
Which conclusions need an official notice?
A recorded interview and a decision notice have different meanings. Do not interpret a closed flag or timestamp gap as proof of citizenship or completion of all required steps.
How should I read related applications?
This site explains supplied records. Use USCIS instructions and notices for the current requirements and subsequent steps of your naturalization application.
How do I check processing times and delays?
Use the live USCIS processing-time tool for the appropriate form and category. Its inquiry result, rather than a timestamp in this reader, tells you whether a case inquiry is available. We do not publish a personal decision-date estimate.
How do I analyze my own N-400 export?
Open the official status service for your receipt. If account JSON is available to you, import the complete case response into the free reader. Add matching status or document data only for that receipt. Review the recognized fields and warnings before choosing whether a detailed report would be useful.
