(CNN) -- For African business leaders who study and further their training overseas, returning to the continent can be even tougher. It can be hard for them to commit to returning to the even smaller economies of their home countries, says Krishna Patel, HSBC's CEO for Africa. "You get expatriate Ghanaians and Nigerians with the best will in the world wanting to come back," Patel told CNN. "But they find themselves employed [in Europe or the United States] and think, 'I'm one man, I'm one woman, and I have an opportunity here.'" There is a steady flow of Africans leaving their homeland to study overseas. Students from sub-Saharan Africa are the most mobile in the world, according to the United Nations Educational, Scientific and Cultural Organization (UNESCO).
