i need a suggestion! i have filed my h1 this year, got a reciept number but do not have the approval yet. From the previous thread i came to know that changing F1 to F4 is not that complicated. but i missed one point. since my h1 is also in the process, would it be ok if i allpy for f4 at the same time? or do i have to wait ? if u have some suggestions then please....
