1.you can fill DS156 even in the consulate U.S. Calgary. There are two desktops and one printer there. I saw somebody busy filling the form there. I finished this form one day before my appointment.
( R! x0 e. ]. d, k* [' p2. I don't have experience in your situation. However, I did not see any rejection in Calgary that day I was interviewed. Because everyone was asked to give them a X PRESS envelope. Nobody had the passport returned the same day (that means rejection). More than 120 people were interviewed that morning.
