In case you missed it, Uhuru Kenyatta recently reversed the new rule requiring foreigners wishing to enter Kenya to apply for the visa online.
Those wishing to do so, can apply for the visa as advised on the new online portal, read instructions here.
However, if you decide to travel abruptly, you are still able to apply for the visa on arrival at the airport in Kenya. Those who were afraid of reducing their last minute travels to Kenya, need not worry.
If on the other hand, you prefer working with people rather than machines, you can apply for the visa at the Kenyan Embassy in Berlin. Just remember to hand in your application on time.
