Expiring Passport?
My Canadian passport is up for renewal in 2029 (my TN extends beyond this). What is the process for renewing on a TN? Do I have to contact CBP and tell them the new number? I got my first TN when they were still doing stamps. Will it be a problem if my new passport doesn't have one? I don't live near a Canadian border so I was considering filing for renewal from the US... help!
