How It Works
A transparent bridge to your own USCIS case data using the exact same internal APIs that power the official myUSCIS dashboard. Here is how it functions and why it is 100% secure.
Step-by-Step Guide
Log In to USCIS
You must be logged into your account at my.uscis.gov/account on this same browser. This establishes the secure session cookie needed to fetch your case telemetry.
Enter Your Case Number
Enter your receipt number into the input field on the home tracker.
IOE (Electronic System). Legacy paper prefixes (like MSC or YSC) do not have this internal API endpoint.Even Easier: Use Our Free Chrome Extension
Skip manual copy-pasting entirely! Our free Chrome Extension automatically fetches all 4 API endpoints and fills the analysis box in one click.
Get the ExtensionGet Data & Copy JSON
Click the generated links (e.g. "Open Status Data"). A new browser tab will open with raw text (JSON). Select all text (Ctrl+A / Cmd+A) and copy it (Ctrl+C / Cmd+C).

}Paste & Analyze
Paste the copied text into the analysis box and click "Analyze". The decoder will interpret the internal codes, location milestones, and hidden silent update flags for you. For the data above, the report looks like this:
Sample report with made-up case data. Checked May 12, 2026.
- Apr 1, 2026 · Database Checks Received
- Mar 27, 2026 · Fingerprints Taken
- USCIS updated your case record on May 2, 2026 without a new public event (a silent update).
Your background checks are moving, while the public status stays the same.
Since your receipt, USCIS scheduled your biometrics (IMAG, March 13), took your fingerprints (FNB, March 27) and received your background check results (FTA0, April 1). The public tracker still says "Case Was Received". Your record was also updated on May 2 with no new status or event: a silent update.
Case Flags & Status
USCIS changed your record on May 2 with no new status or event. The public tracker doesn't show this.

my.uscis.gov servers. We do not invent or modify the data; we simply parse and visualize the raw response.Technical Explanation
The links generated by this tool (like CaseStatus and CaseHistory) point to internal API endpoints. These are the same endpoints the myUSCIS web application uses behind the scenes to render your dashboard.
These endpoints were discovered through standard browser network inspection. They are session-based interfaces that return structured telemetry data (like NIEM event codes, active adjudicator locks, and silent timestamp updates) that the simplified public tracker does not show.
