About CaseStatusTracker
Independent USCIS case JSON reader: paste your own data to see a timeline, event codes and timestamp gaps. Runs in your browser, no sign-up needed.
CaseStatusTracker is an independent tool for understanding USCIS case data you already have. Paste a case JSON object or select a local .json file and it builds a chronological timeline, explains supported event codes and recognized status fields, and flags missing information and timestamp differences, including a Silent Update Checker. Free analysis runs in your browser: the JSON is not uploaded and no account or card is needed. Optional paid reports: $2.99 for one detailed report (90-day private access) or $29.99 per year for annual access. It is not USCIS, a government agency or a law firm, and it does not predict approval dates. Verify decisions through official USCIS notices.
