About CaseStatusTracker
Updated · Editorial review pending
Why we built an independent, browser-local reader for USCIS case data.
A clearer view of data you already have
CaseStatusTracker turns user-provided case JSON into a readable timeline. Our focus is understanding the structure of the supplied data, showing missing information, and making uncertainty visible.
Independent by design
We are not USCIS, a government agency, or a law firm. We cannot access internal agency systems, accelerate a case, or confirm a decision. Official notices and USCIS resources remain the sources for official case information.
Current availability
The JSON reader, timeline, and timestamp comparison work locally in your browser. Optional redacted case storage is available only in environments where it has been enabled after migration. Paid reports are still in development. We do not claim a reviewed event-code dictionary or expert credentials that have not been established.
Independent service. Not affiliated with USCIS or the U.S. government.
