Yes, in some cases, travelers are required to apply for a Kenya transit ETA if they don't leave the airport. This visa is typically used for job transfers or when passengers connecting to other countries via Kenya may want to make a short visit. With this type of visa, individuals can stay in Kenya for up to 72 hours during their transit.
If you are considering a short visit or layover in Kenya but staying within the airport, it is advisable to check with the Kenyan embassy or consulate in your country or visit the official Kenya Immigration Services website for the most up-to-date and accurate information on transit visa requirements.
Keep in mind that specific circumstances, such as the purpose of your travel or the duration of your stay, can impact visa requirements. Always confirm the latest information closer to your travel date to ensure compliance with the current regulations.
