Processing times for various form types are available online. The USCIS uses two methods for calculating these times. In the standard method, the agency has a cap of 130% of the duration. In the new method, the agency shows you the time for processing 50% and 93% of the applications respectively. This new method is available for 14 different forms including the following (Fort Smith times):
- N-400 (Naturalization): 12 to 17.5 months
- N-600 (Certificate of Citizenship): 6.5 to 14.5 months
- N-600K (Citizenship and Issuance of Certificate): 10 to 22.5 months
The duration may be different for another location. If your case is taking more time than expected to process, then you can request information from the agency. For this, you will have to see the case inquiry date given on the same page as the processing info. Besides the inquiry date, the page will also guide you on inquiry eligibility and submission.
