I am sure there are other people who will be able to give you better suggestion. Here are my two cents:

I don't think you will be able to get into any university with that kind of grades. How about starting all-over again? Why don't you write an e-mail to the nearest community college and see if you will be able to join then. You could use some of the credits from Nepal and get an associates degree. Then you can think about transferring to a university.

I don't have any personal experience/knowledge in this regard. I am just trying to start a discussion so that other people can suggest you. Good luck buddy!!
