Couple checking N-400 case status and processing times on a laptop at home

After filing Form N-400, your USCIS online account will show status updates as your application moves through each stage. Most applicants wait 4 to 12 months from filing to oath ceremony, though timelines vary by field office. Understanding what each status means can help you know what to expect and when to take action.

How to Check Your Case Status

You can check your N-400 status in two ways:

  • Online case status tool: Go to egov.uscis.gov/casestatus and enter the receipt number from your Form I-797C, Notice of Action.
  • USCIS online account: Log in to your account at my.uscis.gov to see your latest status and any notices.

Your receipt number starts with three letters (such as IOE, MSC, or LIN) followed by a series of numbers. You received this number when USCIS accepted your application.

Case Was Received

This is the first status you will see. It means USCIS has received and logged your N-400 application and assigned a receipt number. At this point, your application is in the queue for initial processing. No action is needed from you.

Case Is Being Actively Reviewed

This status means a USCIS officer is working on your file and background checks may be running. This is the most common "waiting" status, and it can last several weeks or months. It does not mean there is a problem. No action is needed from you. The most common next update is Interview Was Scheduled.

Interview Was Scheduled

This means USCIS has set a date, time, and location for your naturalization interview. You will receive a notice (Form I-797C) by mail with the details. This is a good sign because it means your background checks are complete and your application is moving forward.

Request for Evidence Sent

If you see this status, USCIS needs additional documents or information from you. You will receive a notice explaining what is needed and a deadline to respond. Respond promptly and completely. Missing the deadline can result in your application being denied.

Interview Was Completed and Case Must Be Reviewed

This status appears when the interviewing officer needs additional time or supervisory review before making a decision. According to USCIS policy, the agency generally has 120 days from the interview date to issue a decision. While this can feel stressful, it does not necessarily mean something is wrong.

Case Was Approved

Your naturalization application has been approved. You will soon receive a notice scheduling your oath ceremony. At the oath ceremony, you will take the Oath of Allegiance and officially become a U.S. citizen.

Oath Ceremony Notice Was Mailed

This is the final status before you become a citizen. USCIS has mailed your oath ceremony notice with the date, time, and location. Check your mail carefully and make sure you can attend.

Typical Processing Timeline

Overall processing times depend on your USCIS field office. According to USCIS processing time data, most applicants can expect:

  • Filing to biometrics: 1 to 3 months
  • Biometrics to interview: 2 to 8 months
  • Interview to oath ceremony: 1 to 6 weeks
  • Total from filing to oath: 4 to 12 months

You can check current processing times for your specific field office at egov.uscis.gov/processing-times.

What to Do While You Wait

The time between filing and your interview is the best window to prepare for the civics test and English assessment. Citizenry helps you make the most of that time with flashcards, quizzes, and mock interviews so you are ready when your interview date arrives.
