San Ysidro is the main border crossing for daily commuter traffic between the US and Mexico. Securing a SENTRI appointment without an automated monitoring service active is nearly impossible.
We check San Ysidro 24/7 and text you within seconds of an appointment opening up.
A common misconception is that you must apply to San Ysidro if you cross via San Ysidro. This is false. The operational databases behind Otay Mesa and San Ysidro share the same underlying availability constraints. If you see an earlier appointment at Otay Mesa (which is just a few miles away), you can and should snipe it rather than waiting for a San Ysidro slot.
This is why ApptHelper.com tracks all local ports for our southern border clients, maximizing the speed at which you acquire your physical SENTRI pass.
San Ysidro is the primary pedestrian and vehicle crossing between Tijuana and San Diego, while Otay Mesa handles more commercial traffic. For SENTRI enrollments, they share the same extreme backlog. Grabbing an appointment at either center is acceptable, so you should monitor both.
Yes, if you use an automated alert to snipe an earlier date at Otay Mesa, you can simply cancel your San Ysidro appointment and reschedule without penalty on the TTP portal.
