I have triple citizenship (Canada + two others). I did not list my non-Canadian passports on my Nexus application because I did not know it was required. Now that I am conditionally approved, I was planning to be upfront in the interview and let them know about all 3 passports right away.

I called the Niagara Falls Enrolment Center and the person on the phone told me that while I should have listed all my passports, I should still bring them all to the interview so they can be added to my application.

Any advice before I attend?
