You can get your status changed from B2 to F1 after you get approval and I-20 from an recognized university or institution.
Is that a law/rule you can point me to that says that? Plus what if the person has no intention of studying at POE but changed his/her mind a couple of months after entering.One also needs to state their intentions at the POE with regards to possible COS to F-1 when entering on B-2.
