Cases usually take months to process and with some case types the duration can extend to years. You can check the processing times from the USCIS site by sharing your office and form type. Here is an example of processing times at the Raleigh field office:
- Naturalization (N-400): 7 to 13 months
- Certificate of Citizenship (N-600): 6.5 to 16 months
- Citizenship and Issuance of Certificate Under Section 322 (N-600K): 6.5 to 25.5 months
The USCIS calculates processing times using recent processing data. The times you see are in the standard format or the format given above, depending on your form type.
Besides processing time, another important piece of information the USCIS provides is the date on which you can ask about your case. Given on the same page as the processing info, the “receipt date for a case inquiry” provides this vital information. If the receipt date you see on your notice comes before the inquiry one, you can ask about the delay.
