Case Track turns USCIS receipt numbers into status alerts
A multilingual immigration case tracker that reads public USCIS status information and promises optional notifications when a case changes.
Field notes
Case Track describes a receipt-number workflow built around the public USCIS Case Status API: users enter the three-letter, ten-digit identifier from Form I-797, review the status and history USCIS provides, and optionally enable change notifications. The page lists EAC, LIN, SRC, IOE, WAC, MSC, and NBC among its example prefixes. It also specifies that cross-device syncing would use an optional email account, while the planned app avoids USCIS passwords, Social Security numbers, and A-numbers.
