entering US on B2 earlier inspite of having valid F1

[yashpatel77]

I have a valid F1 AND B2 visa but i want to enter US before the time frame allowed on F1 STATUS...so can I enter on B2 and then get a stamp on F1 once i am in the 30 day time frame?
Any help is more than welcome

You should come in as F-1, unless you'd like to travel back and come back again. This is because of SEVIS.
