Filing H1 and F1 at the same time

Hello,

I am currently in US on H4.I have applied for H1B FY 2014 and got through the lottery. It is currenlty in RFE. Meanwhile i also have an admit for MS and a possiblity for funding. Can i process my F1 simultaneously? can H1 and F1 process happen at the same time?

Yes, you can file COS from H-4 to F-1. However, this starts a race scenario - H-4 to H-1 COS and H-4 to F-1 COS.

In this case, your final status is determined by the COS which has the later effective date.
