During the last London Tourism Fair (WTM) in November 2013 (we were there!), Kenya, Uganda and Rwanda announced the introduction in January 2014 of a single tourist visa between these 3 countries, allowing free movement from one country to another. This visa, which has now been implemented, is valid for 90 days and costs $100. Each of these countries nevertheless keeps its own visa. We hope (it is planned) that this single visa will soon be extended to Tanzania and Burundi, the other 2 countries of the East African Community
