Checking USCIS by hand stops working around 50 cases.
Firms start searching for a USCIS API when someone on the team is spending hours a week pasting receipt numbers into the USCIS website.
The website is one case at a time
USCIS's public case status page takes one receipt number per lookup. A firm with 300 open cases can't realistically check them all every day.
Access takes an application
The official API is offered through the USCIS developer portal. Production access requires registering, describing your use case and waiting for approval.
A status is not an alert
The API answers "what is the status now". It doesn't remember yesterday's status, notice that it changed, or tell your paralegal. All of that is yours to build.
What CaseTracker runs on top of USCIS for you
- 01
Import your receipts
Upload an Excel or CSV file with receipt numbers, client names and form types. Hundreds of cases import in one go.
- 02
We check USCIS daily
Every active receipt is checked each day. Temporary USCIS errors are retried automatically, and an outage never counts as a status change.
- 03
Changes reach your team
When a status really changes, the people who asked for that kind of update get it by WhatsApp or email, and the case rises to the top of the dashboard.
Everything you would otherwise have to build
Scheduling and retries
Daily checks across your whole caseload, with automatic retries when USCIS is slow or returns an error.
Change detection
We store each case's previous status, so only real movement triggers alerts, not the first lookup after import.
Per-person alert rules
Each team member chooses which events they want, such as RFEs, appointments, approvals or denials, and on which channel.
History and audit trail
Every status a case has had, with dates, plus an Activity page showing what changed and who was told.
Exports
Download your cases and their status history as CSV for reporting or your own systems.
Team access
Owners, admins and members share one caseload, with no keys or credentials to hand around.
Building on the USCIS API vs using CaseTracker
| Build it yourself | CaseTracker | |
|---|---|---|
| Getting access | Apply on the developer portal and wait for approval | Sign up and import cases the same day |
| Daily checks | Write and host a scheduler | Included |
| USCIS errors and outages | Your code has to handle them | Retried automatically; outages don't create false alerts |
| Knowing what changed | Store and compare every status | Built in, with full history |
| Telling the team | Build email and WhatsApp sending | WhatsApp and email, chosen per person |
| Ongoing cost | Developer time and hosting | From $100 a month |
What to know before building on the USCIS API
What the API returns
The case status API takes a receipt number and returns the current status text and description, the same information a person sees on the USCIS case status page. It doesn't push updates to you. To find out when something changes, you have to ask again for every case.
What a firm actually needs
In practice, firms need four things on top of the raw lookup: a schedule that checks every open case, a record of each case's last known status, rules for who should hear about which kind of change, and a reliable way to send those messages. Each one is a small project, and together they're a product to maintain.
There are also edge cases: receipt numbers USCIS can't find yet, cases transferred between offices, and days when USCIS is slow or down. A homegrown script that treats an error as a status change will send your team false alarms.
When building makes sense
If you have in-house developers and want status data inside your own case management system, the API is a good fit. If you just want your team to know when a case moves, it's usually faster and cheaper to use a tool that already does it.
Questions firms ask us
Does USCIS have a public API for case status?+
USCIS offers a case status API through its developer portal. Access to production data requires registering and getting your use case approved. It is not an open, keyless public endpoint.
Do I need my own USCIS API key to use CaseTracker?+
No. You add receipt numbers and CaseTracker handles the checks. There are no keys, servers or code on your side.
How often are cases checked?+
Every active case is checked against USCIS once a day, with automatic retries if USCIS returns an error.
Can I get the data out?+
Yes. You can export your cases and their full status history as CSV at any time.
Can we try it before paying?+
Yes. Every account starts with a 14-day free trial for up to 20 cases, no credit card needed. Plans after that are $100 a month for up to 120 active cases and $150 a month for up to 400, with custom pricing above that.
