Case Track US Immigration

See where your USCIS case stands, and practice the 2025 civics test — in English, Spanish, or French. Look up the public status from your I-797 receipt number. Get a notification when it changes. Study the 128 official questions with flashcards, a spoken practice interview, English writing, and 12 study podcasts. Type the receipt number from your I-797 notice (3 letters and 10 digits). Case Track looks up the public status through the official USCIS Case Status API. You get the current status, a short “what this means” note written by us, and the history USCIS provides. Turn on alerts if you want a notification when USCIS updates a case you follow. You can use the app without an account. If you want the same cases on more than one phone, create an account with your email. We never ask for your USCIS password, Social Security number, A-number, last name, or street address. Civics practice is optional and is in the same app. The 2025 test has 128 official questions. At the interview, USCIS asks 20 and you need 12 to pass. Practice with flashcards, a spoken practice interview, English writing, and 12 study podcasts with AI voices. This is practice only — not the real USCIS interview. The app is free. No ads, no subscription, and no in-app purchase.
