Hi

Guide me

I m n US on B1/ B2 visa for USMLE xm.instaed of going back to india & coming again for hospital interview( more costly )... should I change visa status B2 to F1 ?

Afterwords for MD medicine I hv to take J1 or H1 visa.. so how this B2 to F1 change will affect J1 or H1 processing?

Is possible to convert F1 to H1 in US only?

You cannot keep changing your status like that. For non-immigration category, you can change your status while you are in US only once, and term of both must not exceed 12 months.
