VisaSentinel Pro

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 using a randomized "human-like" timer to avoid detection. 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.

How it works:

1. Purchase a Lifetime License right here (no recurring subscriptions!).
2. You will instantly receive an email with your unique License Key and a simple PDF Installation Guide.
3. Install the free extension from the Chrome Web Store, paste your key, and your Pro features are permanently unlocked.
