BLS Visa Monitoring & Alert Automation.
Continuously monitors BLS visa application centres for new appointment slot openings and alerts users in real time — a domain where slots vanish in seconds and manual monitoring is futile.
/ 01
Key features.
- 24/7 polling of BLS portal endpoints across multiple consulates
- Real-time alerts via WhatsApp, Telegram, email
- Auto-fill assistance to claim slots before they're gone
- Multi-applicant support (families, agencies, expat groups)
- CAPTCHA solving via vision API
/ 02
Architecture.
Distributed scraping cluster — each consulate has dedicated headless browser workers that poll on configurable intervals, respect rate limits, and rotate IPs. Detected slot changes fan out to a notification queue that pushes through user-preferred channels in under two seconds.
