Hey Peter1234,

I am also in same situation and trying to change to f1. My prob is I do not have pay stub. I did little research and found out that I have to submit paystub to show that I was in status while in h1.If you have paystub for at least 2-3 months you wont have problem to change to F1 when the college accept you to admit.

If anyone has changed from h1 to f1, please share.
