Depending on the application (naturalization, citizenship, etc.), it can take the agency months to years to process the application. As an applicant, you can follow your case and get the processing times 24/7 from the USCIS website.
The agency usually updates its site with the latest processing times every month. You can see these times by entering the office location and application type. Here are the processing times for the N-600, N-600K, and N-400 applications at the Saint Paul office:
- Naturalization (N-400): 16 to 19.5 months
- Certificate of Citizenship (N-600): 6 to 15 months
- Citizenship and Issuance of Certificate (N-600K): 10 to 23.5 months
The USCIS is piloting a new method for processing times for 14 different forms including the three mentioned above. For these applications, the second figure in the time range is for processing 93% of the applicants, and the first one is for 50% of the applicants.
It’s clear from these times that there can be a difference in the rate at which forms are processed. For example, it took 16 months to process half of the N-400 cases and only 3 1/2 months more to process nearly all. Whereas it took 6 months to complete half of the N-600 cases, and another 9 months to reach the 93% mark.
Another important piece of information available online is the fixed or variable filing fees fur different forms. You can calculate and pay the fee online.
