The waiting period for cases is usually in the months but some application types can take over a year to process. Here are three examples of processing times at the Las Vegas location:
- N-400 (Naturalization): 13 to 16 months
- N-600 (Certificate of Citizenship): 6.5 to 14.5 months
- N-600K (Citizenship and Issuance of Certificate Under Section 322): 10 to 22.5 months
The USCIS calculates these times based on recently completed cases. In the examples given above the maximum times, you see is for handling 93% of the applications. But, also keep in mind that 7% of cases take longer than the given time to process.
Another thing to note is that the agency also uses another format for processing times. The format depends on the type of application form. The above-mentioned format is for several types. You can also submit some forms online –more information on online forms is available here.
