N-400 Case Status: How to Check Your Citizenship Application

Form N-400 is the Application for Naturalization — the citizenship application. Here’s how to check your N-400 case status, the stages from biometrics through the interview to the oath ceremony, and how to be alerted on every change.

How to check your N-400 case status

1. Find the 13-character receipt number on your Form I-797C receipt notice for the N-400.
2. Enter it at egov.uscis.gov/casestatus, or sign in at my.uscis.gov.
3. Or add the receipt number to NoaTracker once and we monitor it automatically with alerts on every change.

N-400 case status stages

• Case Was Received — USCIS accepted your N-400.
• Fingerprints Were Taken — biometrics done (USCIS sometimes reuses prior biometrics).
• Interview Was Scheduled — your naturalization interview and civics/English test notice is on the way.
• Case Was Approved — you passed and USCIS approved naturalization.
• Oath Ceremony Will Be Scheduled / Oath Ceremony Was Scheduled — you take the Oath of Allegiance to become a U.S. citizen.
