Hav f2 till 2017, aplying F1. Can I reenter US on F2, if f1 is denied

I am currently residing in USA on F2 which is valid till 2017. I got admission in MS in a university and want to visit my home country to apply for F1. Please confirm if I can re-enter US on my F2 visa (incase i donot get F1)…

Well, if your F2 Visa is not cancelled by Visa officer at F1 visa stamping, you are fine to enter on F2. If such a case occurs, where F2 is cancelled, then you cannot.
