Need help!!! COS from H4 to F1

[meghagpt]

I applied for COS from H4 to F1 which was approved but I don't have I797A yet with me. It has been around two months. I have some questions in this case.
1) Can I travel to India in this case?
2)While coming back I have to get my stamping done - what kind of i20 do I need in this case?
3)Will I have any problem in re entering USA
I am in my second semesters of masters.

Congrats on your approval.
Here are answers based on my experience.

1) Yes
2) Since your status is changed to F1, you need to go for stamping.
3) Not that I am aware of.

BTW, How long it took for your COS approval.
