Student Visa (F1, F2, M1, M2)

I recently converted my visa from H4 to F1. I have been on H4 for about 5 months now. I couldnt have applied for F1 COS since my school was starting in just a month and my course duration was only 11 months. I had to be on F1 for atleast a year to be eligible for OPT. Sigh, after researching about so many clauses and caveats I finally decided to get my visa stamped under F1 from Canada. Here goes my experience

VO: Hey how are you
Me: I am good sir.How about you?
VO: i20 please?
VO: Why F1 when you can study on H4?
Me: I wanted to get the practical training at the end of the course.
VO: Thats good you have done your research
VO: What did you do back in India?
Me: (Told)
VO: Whos Xyz( financer on i20)
Me: Hes my bro-in- law. He works for a hedge fund in NYC.
VO: Why he and not your husband?
Me: ummmm.. He offered to help. We both have enough funds too. He just wanted to.
VO: ok. What do you plan to do after the course?
Me: Work for a year and move back to India.
VO: What does your husband do?
Me: Works for general motors.
VO: How about your husband then?Will he also move back?
Me: He has been offered a leadership role in GM India. So that's flexible.
VO: (After a lotttt of typing) Allright your visa is approved.

Lasted for about 15 minutes of which 5 minutes was his typing towards the end.

Good luck with everyone who is in my shoes. Hope this helps. Be prepared with all answers important questions like Why F1 and not H4, What plans after the course etc.
