In 2026, U.S. citizens do not need a traditional "visa," but they do require an Electronic Travel Authorization (eTA) to transit through Kenya if they plan to leave the airport. In early 2024, Kenya replaced its old visa system with a mandatory eTA for all visitors. If you are staying airside (inside the international transit lounge) and not clearing customs, you generally do not need an eTA. However, if you have a long layover and wish to exit the airport to visit Nairobi or stay at a nearby hotel, you must apply for the Transit eTA online at least 72 hours before your trip. The Transit eTA is valid for a stay of up to 72 hours. If your layover is longer than three days, you must apply for a standard "Visitor eTA." In 2026, the process is entirely digital, and you must carry a printed or digital copy of your approved authorization to show to airline staff before boarding your flight to Jomo Kenyatta International Airport (NBO).
In 2026, U.S. citizens do not need a "Transit Visa" for Kenya, but they must have an approved Electronic Travel Authorization (eTA) before they begin their journey. Kenya transitioned from a traditional visa system to a "visa-free" eTA model in early 2024. Even if you are just staying in the airport for a few hours to catch a connecting flight, you should have your eTA ready. If you plan to leave the airport (e.g., for an overnight stay in Nairobi), the eTA is mandatory. The application is done online at the official government portal and usually costs around $30–$35 USD. Your passport must also be valid for at least six months from your date of arrival and have at least two blank pages. Essentially, while the "Transit Visa" name has been retired, the "eTA" has taken its place as the required digital gatekeeping document for all international travelers entering or transiting through Kenya.
