Case Status API
Provides case status information to USCIS customers and their representatives who require regular access to case status information.
FOIA Request and Status
This API allows consumers to create a Freedom of Information Act (FOIA) or Privacy Act (PA) request, for Alien File material, about or on behalf of the subject of record by sending a JSON payload with the required data. Once the payload is validated and successfully ingested, a Request Number will be returned as evidence that the request was successfully submitted. When USCIS has created the case, a Control Number will be returned to track the status of the FOIA/PA Alien File Request.
