TN Visa Appointment Wait Times at Buffalo
Updated August 23, 2026 • CBP calendars last checked Aug 23, 2:53 PM ET
There are really two wait times for a TN or L (USMCA) appointment at the Buffalo-area crossings. The posted wait is what most of the calendar looks like when you check casually — right now the median open date is 44 days out. The real wait is set by the near end of the calendar: the earlier dates that cancellations keep putting back into play. Those are the slots that vanish within hours of appearing, which is why casual checking almost never finds them.
As of our last check, the earliest open slot across all three crossings was Tue, Aug 25 at Rainbow Bridge (Niagara Falls, NY) — 2 days from today, roughly 6 weeks sooner than the median open date. Catching the near end of the calendar instead of settling for the middle is how monitoring cuts weeks off your wait.

Why the posted calendar overstates your wait
The calendar you see when you check once is a snapshot, not a schedule. People cancel TN appointments every week — plans change, start dates move, lawyers rebook — and each cancellation puts a slot back on the public calendar at an unpredictable moment.
Our monitors detected 68 distinct appointment openings across the three crossings in the past 30 days, and 82% were gone again by our next check a couple of hours later. If you only look at the calendar occasionally, those openings are invisible: they appear and get claimed between your visits.
In our monitoring so far, new openings have appeared from about 1 days ahead out to the far end of the 60-day window we watch — and the closer the date, the faster it disappears. Booking at the near end of that range instead of the far end is the difference of several weeks.
Three ways to shorten your wait
- Check all three crossings, not one. Peace Bridge, Rainbow Bridge, and Lewiston-Queenston share the same CBP appointment system but rarely have identical availability — the earliest slot is often at the bridge you didn't check.
- Check at odd hours. Cancellations post around the clock, not during business hours, so a calendar that looked full at lunch can have an opening at midnight.
- Or let monitoring do both for you. We watch all three calendars continuously and email you the moment any opening appears, with a direct booking link — so a cancellation for next week doesn't slip past while you sleep.

Frequently asked questions
How far in advance are Buffalo TN visa appointments booked?
It moves week to week. Standard availability on CBP's calendars is often several weeks out, but cancellation slots regularly appear for much earlier dates. The table on this page shows what our monitoring observed at its last check.
Do earlier slots really open up from cancellations?
Yes, constantly. Over the past 30 days our monitoring detected 68 distinct appointment openings across the three Buffalo crossings, and about 82% of them were gone again by our next check a couple of hours later. They go to whoever books first, and the earliest dates are consistently the first to vanish.
Are wait times different for Mexican citizens applying for a TN visa?
Yes. Mexican citizens apply at a U.S. embassy or consulate rather than at the border, and consular interview wait times vary by post. Check the U.S. Department of State's official visa wait-time page for current consular estimates. This page covers the Buffalo border crossings used by Canadian citizens.
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.
