The US interview was... an interview. Much more than the box-checking of the Canadian side, even applying as a Canadian.
However, I'm now approved.
So yeah... make sure you don't skip the US side of the interview

Are you Canadian? So the Canadian government handed off ABTC decision making for Canadian citizens to CBP???
