Just wait until we have to renew our Global Entry/Pre-Check/Nexus programs in 5 years or renew our passports
I was told at my Nexus interview if my passport expires before Nexus, then I'd need to bring new passport in so the info could be updated in their system. No appt required. I did think it odd when we were waiting before our initial interview that several office staff passing by kept asking us if we had an appointment or were drop-ins.
For Nexus renewal, I think I need an interview appt to show I'm still trustworthy. So I have to remember to start the renewal process 3-6 months in advance.
I renewed my passport and was able to update the info on my Nexus profile on-line. Also, did not need to go in for an interview for my Nexus renewal, which was great
as the nearest center is 5 hours away.
