Buffalo TN Visa Appointment Cancellations

Updated October 13, 2026 • CBP calendars last checked Oct 13, 9:50 PM ET

CBP’s Port of Buffalo handles TN and L (USMCA) adjudications by appointment at three bridge crossings, and the booking calendars are often full weeks ahead. What most applicants never see is the churn underneath: people cancel, employers move start dates, and each cancellation quietly puts a slot back on the public calendar.

In our monitoring over the past month, most of those returned slots disappeared again within hours, and many were gone before our next check a couple of hours later. Whoever happens to be looking at the calendar in that window gets the appointment.

That is the whole reason this service exists. We watch the official CBP booking pages for all three crossings continuously and email you the moment an opening appears, with the date, the times, and a direct link to book it.

Frequently asked questions

Do I need an appointment for a TN or L visa at the Buffalo border?

Yes. CBP’s Port of Buffalo requires an appointment for TN and L (USMCA) adjudications at Peace Bridge, Rainbow Bridge, and Lewiston-Queenston Bridge. Appointments are booked through CBP’s official online scheduling portal.

What happens when someone cancels their appointment?

The slot returns to CBP’s public booking calendar and goes to whoever books it first. Because openings appear at unpredictable times and vanish quickly, continuous monitoring beats manually refreshing the page.

Are you affiliated with CBP or the U.S. government?

No. TN Visa Alert is an independent monitoring service. We only track publicly available appointment information and we do not provide legal advice. Bookings always happen on CBP’s official portal.
