sorry for misunderstanding but i did have job and pay stub, and i didnt get another project then i decided to go for change of status. i am sure my f2 COS will be approved in a month or so(it takes 2.5 months to complete the COS)  but the thing is I want to change to f1 before January, for that i must have at least 2.5 months.  thats why i wanted to know if anyone went through this situation?
