Can I get a transit visa for Kenya at Nairobi airport?
Previously, before the Kenya ETA, visitors who needed a visa for Kenya and wanted to leave the international transit region during a stopover had to get a Kenya Transit Visa.
The procedure has evolved since the introduction of the Kenyan ETA. The ETA has replaced the usual transit visa. This implies that if you're transiting through Kenya and want to leave the airport's international zone during your layover, you must first apply for a Kenya ETA.
There is one exception: if you are not leaving the airport's international transit area during a stopover in Kenya, you do not require an ETA. This applies to people who stay in the international zone or switch planes without leaving this region.
