I came to US on a B1/B2 category and wishing to pursue a MS program now. I have not disclosed any intention of studying over here at POE. So how can I change my visa status from B to F1 ? Can I change my status here itself or I will have to go to my home country and get it stamped there and come back ? Which is the best option ? I have not yet applied to any college but i am plannig to do so.
