My sons global entry has expired, however he is conditionally approved for Nexus. (i have a valid nexus card) Can we drive down to the US using the Nexus lane?

Kid(6) is dual citizen, not that it matters.

We have flown into the US and used the Global entry kiosks no problem, but I am not sure what the procedure is for land since its usually the card that we have to show. Is it still cool for us to use the lane?

Incidentally and i know it does not matter, we are only driving because we are going to the blaine enrollment center.
