In 2026, U.S. tourists no longer need a "traditional" visa for Kenya, but they must obtain an Electronic Travel Authorization (eTA) before departure. Kenya officially moved to a "visa-free" system in 2024, replacing it with the digital eTA to streamline entry. You can apply for the eTA online at least three to five days before your trip; it typically costs about $35 USD for a standard single entry. For frequent 2026 travelers, there is a 5-year multiple-entry eTA available for U.S. citizens for a higher fee. Once approved, the eTA is sent to your email and is linked to your passport. You must present a printed or digital copy of the authorization at the airport to board your flight. It is important to note that without an approved eTA, you will be denied boarding at the gate, as there is no "authorization-on-arrival" in 2026.
