Two different situations both end up in the same place: you have a Global Entry interview booked, and now you need a different date — either because your plans changed, or because CBP cancelled on you. The risk people worry about is the same either way: will I lose my place in line, or my Conditional Approval?
Here's exactly what happens in each case.
If You Need to Reschedule Yourself
The TTP portal makes a real distinction between "Reschedule" and "Cancel" — and it matters which one you click.
- Sign in to the TTP portal with your Login.gov credentials.
- Open your scheduled appointments from the dashboard.
- Click "Reschedule" — not "Cancel" — next to your current interview. This holds your existing slot until you confirm a new one, so you're never left with zero appointments.
- Browse available dates in the scheduler.
- Confirm your new date. You'll get an email confirmation.
The catch: when you reschedule, the system only shows you the openings available in that exact moment — not a complete view of everything that might open up later. Reschedule at the wrong time and you can end up with a worse date than the one you started with. If you're not in a rush, it's often better to hold your current appointment and keep checking for a better one separately, rather than rescheduling into the first slot you see.
Cancel vs. reschedule: canceling outright (instead of rescheduling) leaves you with no appointment at all, and you start the booking process from scratch — competing with everyone else for whatever's open. Always reschedule, never cancel, unless you genuinely don't need an appointment anymore.
Your Conditional Approval is safe as long as you keep a scheduled appointment at all times. It's a no-show — missing an appointment without rescheduling first — that puts your approval at risk.

If CBP Cancels Your Interview
Sometimes the cancellation isn't yours — CBP cancels interview blocks for reasons that have nothing to do with you:
- Staffing changes — officers reassigned, on leave, or reduced interview blocks at a center
- Facility issues — building maintenance, security incidents, temporary closures
- Weather or emergencies — severe weather or natural disasters closing a center
- System outages — scheduler or technical failures causing bulk rescheduling
- Government shutdowns — funding lapses that close enrollment centers entirely
CBP typically won't tell you which of these caused your specific cancellation — you'll just get a notice that your interview was cancelled and needs to be rebooked.
What to do: log back into the TTP portal immediately and look for a new slot. Cancelled blocks and other openings get claimed fast by everyone else in the same position. Check more than one enrollment center rather than just your original one — a secondary center 60–90 minutes away may have better odds.
Critically: your Conditional Approval window does not pause or extend because CBP cancelled on you — check your exact deadline in the TTP portal. The clock keeps running regardless of whose fault the cancellation was, so don't wait to rebook.
The Underlying Problem Is the Same Either Way
Whether you're rescheduling voluntarily or recovering from a CBP-initiated cancellation, you're back in the same position everyone in our guide on why appointments are so hard to find is in: competing for slots that disappear in seconds.
This is exactly the scenario automated alert services exist for — you don't have to keep refreshing the portal yourself while you wait for a better date to appear. Appt Helper monitors up to 3 enrollment centers 24/7 and texts you the instant a slot opens, whether it's a routine cancellation or a fresh opening after CBP cancelled your original interview.
