As long as they don't send you to the other line for addition inspection you should be fine. They decided for some reason to put me through an additional check and that made my time through customs almost and hour and a half. Luckily my layover was 3 hours.

I was doing a mileage run to TPE and back and I think they were suspicious that I didn't have hardly any luggage, didn't declare anything, and they seemed really puzzled that I would fly out there to spend one night at a hotel and come right back.
