Ek@l,
       I can fel your situation because my sister also faced the same problems. Just try once for your H1b visa may luck favors this time. If not then once take GRE exam if it's validity expires and apply for PhD. programme. I have heard and saw that PhD. scholars wife are getting visa without any objection means easily.
      For PhD. programme at mgmt. once visit Iowa state university website i.e. www.isu.edu this may help you.

Best

Good luck
