My wife was is in H4 VISA when she entered in to U.S.A which is valid till Jan 1st 2012. After entering US she got admission to a Master Program and converted to F1 Visa. But hasn't left US for F1.Stamping till now. Now we want to convert back to H4 visa from F1. So if she eligable to go back to her old H4. Is it still valid till Jan1st 2012 ? Or do i have to apply for H4 again, which i don't want to do now because my H1-B renewal is in progress and not approved yet. Thanks for you Time. I will would really appreciate your early response.
