I think it really depends on the TRO/TECO and how difficult the officers in charge want to make your life for their own amusement. The passport check phase is supposed to be just a less-than-one-minute thing to confirm that the person in the application, the person in the passport and the person in front of them are the same individual. Decisions are made in Taipei, not at the TRO/TECO. As far as I know (that day I had a brief chat with the staff), from their admin panel they don’t even have access to all of our application details because they are not involved in the selection process, but only in the subsequent verification part.
Oh man, I feel for you
