CaseLens — Unofficial USCIS Case Tracker 作成者: Eric Qiu

CaseLens adds a panel to my.uscis.gov showing every case on the signed-in account in one place.

Unofficial and independent. Not affiliated with, endorsed by, or connected to USCIS or the Department of Homeland Security. Nothing it shows is legal advice or an official determination. Mailed notices and the official website remain the authority on any case.


Your account page already loads your case data when you open it. CaseLens makes those same requests and lays out every field they return — including fields the page itself does not display — for all your cases at once, rather than one at a time.

• Every case at once, one line each: form, status in the agency's exact wording, and the date of that status.
• A merged timeline of status history and logged event codes, with the source of each entry named.
• A stage map built from the case’s own record: a step appears only when USCIS logs activity for it. Steps a form’s instructions provide for but this data does not report are marked “not reported”, never guessed.
• Which office holds each case. The website does not display this.
• When a record was last touched even though the status text did not change. The website does not display this either.
• Documents on file, scheduled appointments, and days elapsed since filing.
• A badge naming what changed since the last visit.
• "Everything USCIS sent": every response in full, one section per request, each field labelled and in the agency's own order, nothing filtered out.
• Nicknames, a JSON export of your full case record, receipt-number masking, and dark mode.
• Spanish status wording where it is supplied.

• Runs entirely in your browser. No server, no account, no analytics, no telemetry, no advertising.
• Makes no request to any site other than my.uscis.gov, and loads no outside code, fonts or images.
• Cases, history and settings are stored in this browser and are never transmitted anywhere.
• Read-only. Nothing can be filed, answered, withdrawn, uploaded or changed.
• No permissions beyond running on my.uscis.gov itself. One content script, on https://my.uscis.gov/* only, and no background script.
• Settings → Erase everything removes all stored data.

Works with receipt numbers beginning IOE. Signed out, the panel shows nothing.
