yes sampu, you are very lucky individual.  you did not have to work hard here to get your degree.  you have room to live, food to eat and at the same time going school and that too paying only instate like all the americans do.  very lucky indeed.  so, stick with H4 and enjoy your cheap education.  you can find job later with your masters degree.  as somebody said, prolly by that time you will have EAD or greencard, so no problem at all.  consider yourself lucky.  prolly you have not seen so many nepali students out here who are struggling to pay tuition.
