I had my interview in montreal on Feb. 28th. overall a good experience, nothing scary about it! so dont worry so much! i stayed at the travelodge only a few blocks from the embassy, the room was small but was reasonably priced and continental breakfast included. parking there overnight was extra $18.
I arrived at the consulate at about 6:30 am, no one there waiting so i was first in line (YAY!) when the doors opened they let us in 1 by 1 and asked for Loomis confirmation and passport. put a sticker on the passport and then went through security. they kept my cigarettes and gave me a ticket to pick them up when my interview was complete. After security you go down stairs and sit as close to the elevator as possible. finally we went up in the elevator, IMMEDIATLEY TURN LEFT TO THE CASHIER COUNTER and they will check you in and give you your ticket (i got c-1 YAY) then a bit more waiting until your number is called. I was asked for a few papers and my fingerprints were scanned. then back to sitting down until my number was called again for my interview. I was asked 3 questions (where do you live? how did you and your fiance meet? and where does he live?)she took my fingerprints again and thats all.. APPROVED!!
I had no problems with having a co-sponsor, so if your in the same boat as me with that dont worry.
