It is the dream of many business people to take their business across the border, and thanks to the East African Community (EAC), a regional economic community consisting of five countries, movement of people and capital is not restricted. The countries include Kenya, Uganda, Tanzania, Rwanda and Burundi. 

Ideally, you should be able to work or do business in any of these countries.
