Case Processing Times

We are testing a new method to calculate processing times for Forms I-90, I-485, I-751, and N-400. With this method, we can post processing times that are more accurate, timely, and easier to understand.

What do the processing times mean?

Example Time Range

We now show case processing times as a range. The first number is the time it takes to complete 50% of cases (the median). The second number is the time it takes to complete 93% of cases.

For non-pilot forms, we will continue to use our old method to calculate processing times, but will add an upper limit that is generally 130% of the processing time.

We calculate processing times by using historical data of completed cases. We cannot project how long it will take to complete a case filed today.

Where can I find my form number and the office that is processing my case?

Your receipt notice has key information you will need to determine your processing time.

Sections of a receipt notice with the following key information highlighted: 1. Form Type or Case Type; 2. Receipt Number; 3. Receipt Date; 4. USCIS Office.


If the “USCIS Office” is the National Benefits Center (NBC) and you have filed an employment-based or family-based Form I-485, Form N-400, or Form N-600, you should check processing times for your local field office.

When can I ask about my case?

We have posted a “Receipt date for a case inquiry” to show when you can inquire about your case. The “Receipt date for a case inquiry” is the upper end of the range (converted to a date). If your receipt date is before the “Receipt date for a case inquiry”, you can submit an “outside normal processing time” service request online.
