Cancellation Monitoring: How Most Appointments Are Actually Found
Why 80% of interviews come from cancellations, not newly released slots. Master the art of catching newly released Global Entry appointments before they're gone.
The Hidden Truth About Global Entry Appointments
Most people believe they need to wait for CBP to release new appointment slots. In reality, the vast majority of available appointments come from other travelers canceling their existing bookings. Understanding this dynamic is key to finding appointments faster.
The 80/20 Rule of Global Entry
- 80% of appointments become available through cancellations
- 20% come from new slots released by CBP
- Cancellations happen constantly throughout the day
- Speed matters most - the first person to see a cancellation gets it

How Cancellation Monitoring Works
The Technical Process
- Someone cancels: Appointment slot becomes available in CBP system
- System updates: Slot appears in online booking system
- First come, first served: Available until someone books it
- Typical window: 30 seconds to 5 minutes before someone else claims it
Why Speed Matters
Cancellation slots don't "queue up" or wait for anyone. They're immediately available to the next person who refreshes the page or checks the system. The person who sees it first gets it.
