Overview
Monitors US visa OFC appointment slots and alerts you via Telegram when slots become available.
Stop refreshing the portal. Let VisaSentinel find your appointment for you. Trying to book a US Visa OFC appointment can be a nightmare. The portal doesn’t notify you when slots open up, forcing you to manually log in and check dozens of times a day—risking being locked out or thrown into a waiting room. VisaSentinel is a Google Chrome extension that completely automates this process for you. It sits quietly in the background of the scheduling portal, checking for open slots at regular intervals. The moment slots become available, you are instantly alerted so you can grab them before anyone else. What you get with VisaSentinel Pro: 🚀 Automated Monitoring: Set your check frequency (e.g., every 10 minutes) and let the extension do the hard work. 📱 Instant Telegram Alerts: Get a message pushed directly to your phone the exact second slots are found. 📅 Date Range Filtering: Only want slots in June or July? Set a date range and ignore the rest. 🏥 Dead Man's Switch: Connect Healthchecks.io to get a separate alert if your browser crashes or your session expires. 🛡️ Smart Error Recovery: Built to survive the portal’s notorious crashes, waiting rooms, and token expirations. 🔥NEW in 1.1.0! Our crowdsourced network: When any user finds a slot, all Pro users instantly receive a notification and/or a Telegram alert! How it works: Purchase a Lifetime License with no recurring subscriptions! You will instantly receive an email with your unique License Key and a simple PDF Installation Guide. Install the free extension from the Chrome Web Store, paste your key, and your Pro features are permanently unlocked. Disclaimer: VisaSentinel is an independent tool and is not affiliated with CGI Federal or the U.S. Department of State. Use responsibly. You agree that using this app will alert other Pro users when you have found slots. This helps keeps the app free but gives you a great incentive to go Pro, so upgrade today!
