How to read the official processing-time tool, what its two numbers actually mean, and when a case is late enough that you can ask USCIS about it.
USCIS publishes current processing times per form and per office on its own tool. This page explains how to read it. We do not reprint the numbers here, because they change constantly and a figure copied onto this page would be wrong within weeks — the official tool is the only current source.
People often read only the first one. The second is the one that decides whether USCIS will answer a question about your case.
Find your form number on your receipt notice, Form I-797C. It is printed near the top, for example I-130, I-485, N-400 or I-765.
On the USCIS tool, choose that form, then the subtype or category if it asks, then the office or service center handling your case.
The service center is identified by the first three letters of your receipt number. Our USCIS case status page explains those codes.
Compare the case inquiry date the tool shows against the receipt date printed on your own notice.
The published range describes typical cases. Several ordinary things move a case outside it, and none of them means something has gone wrong.
Once your receipt date is earlier than the case inquiry date shown for your form and office, you can submit a case inquiry to USCIS. That is a specific process with its own form and its own expectations.
How to submit a USCIS case inquiry (e-Request)USCIS offers faster adjudication for certain form types and categories, for an additional fee. Which forms qualify, and the fee, both change — USCIS publishes the current list and amount on its own premium processing page. Not every form is eligible, and paying for it does not change the decision, only the speed of it.
