I am on H4 visa status... nd my husbands H1 expires next month...
Is there any way, we both could stay here...
I am planning to take up any course and change to F1 , so that he could take F1 dependent status.

Will the time be sufficient... Plz suggest some universities
I am a science graduate

You can change your status from H4 to F1 and your spouse can change to F2. However, processing time is between 60-90 days.
