if you're on yourlast semester, just finish it up. Go talk to the cashier's . They usuall let you sign for promosory note. I paid my last semester's tution after working in opt for a year. they do however hold your transcript and diploma. As long as you leaving usa goes, no they can't stop you. But finish it up no matter how hard it is.. apply for opt, take some loans whatever.. there are contracting agencies who'll hire you no matter what your major is after graduation...just finish it up.. you'll feel better for all your life...
