We may be going through Detroit on our way to Canada from the USA and my wife and I each have new passports since obtaining Nexus. If we do make the trek, we plan to stop at the Nexus enrollment center at the Ambassador Bridge to make sure everything is up to date. I believe we can do a walk in for this? Does anyone have any experience with this center? When we went for our interview there, after you exit it pushes you back to the USA side, but there must be a way to get back Canada bound since I suspect that there are people working there that travel back to Canada each day? Any idea how to get back out and continue on the way to Canada?
