How to Check Your USCIS Case Status
Only USCIS's own system is accurate for case status. This page gives you the official lookup and explains what a receipt number is made of, why status updates lag, and when you are allowed to submit a case inquiry. Your receipt number is in the upper-left corner of the I-797C receipt notice.
Your receipt number is on the I-797 notice USCIS mailed you — usually three letters followed by ten digits. If nothing comes up, check the letter prefix first (IOE, LIN, SRC, WAC, EAC, MSC).

About Receipt Numbers and Status
The first three letters are the service center
Common prefixes include IOE (filed online), EAC/YSC, LIN, WAC, SRC and MSC/NBC. The prefix doesn't tell you how fast your case will move, but it does tell you which center handles it.
Status updates are not real time
Changes in the system often lag behind what has actually happened, and some internal steps are never shown. A long stretch with no change does not necessarily mean your case is stuck.
You can only follow up after normal processing time
USCIS publishes a processing time range for each form and service center. It accepts a case inquiry only after the posted "case inquiry date" has passed.
Frequently Asked Questions
- What does "Case Was Updated To Show Fingerprints Were Taken" mean?
- Usually that your biometrics have been collected and entered. It is a routine step in the middle of the process and does not mean approval is coming soon.
- What if the online status doesn't match a letter I received?
- Go by the written notice. The online status can lag or be simplified; the official decision is always the paper or electronic notice.
