Just thought of posting my experience in Calgary for anyone who is planning to get their visas stamped in Canada. Though, I never got an replies back for the questions I had, hopefully this answers a few questions to people who intend to get their visa stamped F1 to H1B.
I got my H1-B revalidation successfully done and got my visa back the same day. There were no hiccups through the process, but I wouldn't call it very straight forward either.
I reached the US consulate at 8 am for my 9 am appointment. The security check took a long time to get through, He didnt let us in until 8.30 am for a 9.00am appointment. We were not allowed to take any bags, electronic equipment or beverges or food there. So I had to carry all my paper work in folders. After the security check, we were taken to a room, the place wasnt very crowded (about 20 people but the strength went up with time) but there was only one officer conducting the interview so it took a little while. I was called at the counter twice, once to submit my paperwork, pay the fees ($100 cash) and the second time for an actual interview.
I was asked to show my expired I-20s, EAD (opt) card that was issued after graduation and I-797 to verify that I wasn't out of status anytime. The questions asked were, what was my purpose of visit to Calgary, when and where I got my Masters degree from and when do I intend to fly back to Houston ("if I did"). The only problem I ran into was my last name since, my passport does not have anything written on my last name (am a south indian so didnt have a last name in india but my middle name became my last name when my F1 visa was issued and has stayed tht way ever since), the officer said she couldn't understand about it and thats not the way it happens in US. She said it is always recommended to go back to one's own home country to get their visas stamped. That probably was the only moment my heart skipped a beat, but fortunately it went through. I was asked to collect my passport (still does not guarantee the visa issuance) at 3 pm after paying the reciprocity fee ($50 cash) and I got out at around 10.00 am. I was still a little nervous when I picked up the visa at 3 pm. Well, I got a multiple entry visa valid for 3 yrs. There were a couple of other guys with similar cases, one of them was asked to come after a week due some security clearance issue, rest were approved.
Any questions, I will be happy to answer to the best of my ability.
