The processing time for the N-400 application varies by USCIS service center and location but typically ranges from 6 to 14 months.
Processing times vary depending on the workload of the USCIS field office where your application is assigned. Filing online can streamline some steps but does not drastically reduce overall processing time.
Once USCIS receives your application, they issue a receipt notice (Form I-797C) to confirm they are processing your application. Other steps, like biometrics and the interview, follow.
The biometrics appointment notice is typically sent 1-2 weeks after USCIS receives the application. The appointment is usually scheduled within 3-8 weeks of filing.
If your case is delayed beyond the normal processing time, you can submit a case inquiry online to USCIS or contact the USCIS Contact Center for assistance.
