Hi Shuaibks, I am Annie who called you on the 11th, Nov from China, thank you very much for the instruction of calling Vancouver IAD, guess what? yesterday we tried the same number, and as you told us, dial 1 then quickly 0, there was a lady answered the phone. We confirmed with IAD the full hearing date, and now im booking the flight tickets for my husband to Vancouver from China, a round trip, he only will stay there from 13th, Dec, attend the hearing on 14th, then come back on the 15th. Thanks again for the information, really appreciated. Best wishes.
