Start Date Approaching, But No TN Appointment Available?

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

Your U.S. job offer has a start date. CBP’s Buffalo calendar shows nothing until weeks after it. Before assuming the date has to move, it helps to know that the calendar you saw is a snapshot, not a fixed schedule.

Three things actually work. First, watch for cancellations: returned slots show up at all three Buffalo-area crossings, often for much earlier dates, and most are rebooked within hours. Second, check every bridge, not just one; Peace Bridge, Rainbow Bridge, and Lewiston-Queenston frequently differ. Third, check at odd hours, because cancellations post around the clock, not during business hours.

Doing all of that by hand means refreshing three calendars dozens of times a day. We built TN Visa Alert to do exactly that job: continuous monitoring of all three crossings, with an instant email and direct booking link the moment any opening appears.
