How do I read my USCIS case JSON?

Paste or import your own JSON, choose Analyze free preview, then review the event timeline and warnings. The free analysis runs locally; saving or purchasing a report is optional.

  1. Choose data you are authorized to view

    Use your own case JSON. Remove passwords, cookies, tokens and identity documents before pasting. Do not share USCIS login credentials.

  2. Paste JSON or choose a local file

    Provide a case object or an object containing it under data. For a detailed timeline, events must be an array. A supported status-only export can be read with reduced detail. The reader accepts up to 1 MB and 2,000 events.

  3. Analyze and inspect the result

    Choose Analyze free preview. Review the event order, missing timestamps and data warnings. Unknown event codes remain unverified.

  4. Check important information with USCIS

    Compare important actions with official USCIS notices and Case Status Online. A timestamp difference alone does not predict a decision.

How do I read USCIS JSON fields safely?

Separate the supplied status, event codes and record timestamps. Missing fields stay missing; unlisted code meanings are not guessed.

  • A data envelope and a case object are supported; a login page or null is not case JSON.
  • Case data, optional status and documents must concern the same receipt.
  • Free analysis runs locally. Saving or preparing a report requires a separate consent action.

Where should I verify my official case status?
