Hey there, I'm sorry for your situation. That does indeed sound very frustrating. As for good Universities abroad, the University nearest to me is actually a very good school, and very accepting of foreign students. In fact, I've met several people from Africa who came here to study and have been very successful, one woman even from Nigeria. The school is UT- University of Texas at Austin here in central Texas, USA.

I know the image most people who've never been to Texas associate with Texas is a cowboy, wild west, redneck filled state full of Bubbas and Bobby Joes, and for parts of the state I'll concede that may well be true lol, but most of Texas isn't like that, and Austin is very much a liberal, affluent, cosmopolitan city.
