Renewed my Nexus card by mail last year, haven't travelled on it yet. I am Canadian with an H1B work visa for the USA. Do I need to go to the Nexus office at YYZ before I enter the USA using my new nexus card, to have the work visa linked? Or is it already linked from before? Passport hasn't changed.

I never know what to do and I always seem to guess wrong and get yelled at by the border agents.
