Mrs. Xyzzy and I recently went through the enrollment on arrival process at YYZ. We arrived at the US preclearance area before the CBP "suggested" window of 9:30am-2:30pm so we were a bit nervous as to how long things would take. Once there, we looked for any signs regarding the interview but found none. We didn't want to end up in the gate area and thereby miss a our shot at interviews. So, I asked about this. I was told to follow the normal exit of the preclearance area and to wait in the area immediately outside, and that one officer was working on NEXUS interviews that morning. After exiting via the double doors, we saw this:
Note the "take a number" machine -- it was empty. Fortunately, there were only two people ahead of us, so everyone knew where in line they were. It took about 15 minutes of processing per person. When our turns came, the officer took us together. M
st of the interview consisted of verification of documents, but there were also a number of updates to make since our initial applications. The officer was quite pleasant. We received our approvals while we were still with him. From the time we arrived at the waiting area until the time we left our interview was about 1:10.
