I am going to Toronto Pearson Enrollment Centre next week for my first interview. Applied three weeks ago for Nexus. I checked the available interview slots and found one closer luckily. I have one quick question - I am not flying out of Pearson that day, can I just go to the airport and visit the enrollment center, do the interview and comeback to Toronto and not flying out? I just want to be aware about the logistics and not waste others appointments when I am not sure if this is ok. Thanks.
