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).

As many as one in three higher education students in Botswana, Namibia and Swaziland study abroad according to a UNESCO report. By comparison, one out of every 250 North American students studies overseas.

South African Richard Remmington, an IT manager studying for an MBA at Oxford's Saïd Business School, said there just aren't that many opportunities back home.
