How it works
Receipt number → status → optional alerts
Three steps. The data comes from USCIS. Case Track does not change it, speed it up, or replace the notices USCIS sends you.
Add the receipt number from your I-797
Find it on any notice USCIS mailed you (Form I-797). It starts with three letters — EAC, LIN, SRC, IOE, WAC, MSC, NBC, or another service-center prefix — followed by ten numbers. Give the case an optional nickname if you track more than one.
Read the public status
Case Track looks up that number through the official USCIS Case Status API. You see the current status, what it means in plain language, and the full text USCIS provides — including form type and a masked receipt number.
Turn on alerts, or just check in
Keep a list of cases on the home screen. If you want a notification when USCIS updates one, turn on alerts for that case. Create an optional email account only if you want those cases synced across devices.
