Help me to find a University!

Graduated last year, MBA.
OPT will expire soon. H1-B, not withdrawn.
Need to go back to school to maintian the status.
Spouse is in Nepal.
I thought why not Ph.D. rahter than going back for another degree or community college.
GMAT expires already.

Is there any university who could grant conditional admission on Ph. D.(Economics or management)  program?

Thanks for sharing :)
