As maxpayne has suggested, just go to a community college that is convenient for you and all you do is talk to the adviser there. If you think your English is not very good, you will have to take some classes. Also, because you just have BBS, which is a three years course, you will need some courses to be completed before you go to MBA. Even if you get direct admission in MBA (you can fiind some schools that let you), I would still suggest to talk to some advisers first, because I've there. I did BBS in Nepal, too, and I know the difference.
