The USCIS site provides case processing times for the various types of applications. You can check for processing times by providing your form type and office location. Given below are the San Antonio offices’ processing times for naturalization and citizenship forms:
- Naturalization (N-400): 7 months to 13 months
- Certificate of Citizenship (N-600): 6.5 months to 16 months
- Citizenship and Issuance of Certificate Under Section 322 (N-600K): 6.5 months to 25.5 months
From the times given above, you can see that there is a lot of difference between the two figures given in the time ranges. This is because the first figure, 7 months for the N-400, for example, is the time it takes to process half of the applications, and the second figure is the time for processing over 93% of the cases.
