Eastern European countries provide free or almost free education and in many respects it's pretty good. Many people from Africa or the middle east graduate there especially in medicine and then(sometimes) return back home to become successful doctors. Local specialists are accepted and paid well in the west which creates a deficiency of medical professionals in their country. Also since it's pretty expensive to become a college student in the west, it's not that rare to see people from as far away as USA studying in Eastern Europe.
