As of March 2026, whether you need a transit visa for a 12-hour layover in Dubai depends entirely on your nationality and whether you intend to leave the airport. If you remain in the international transit area of Dubai International (DXB), you generally do not need a visa regardless of your passport. However, if you wish to exit the airport to see the Burj Khalifa or stay in a hotel, citizens of many countries (including the US, UK, EU, and many others) can receive a free 30-day or 90-day visa on arrival. If your nationality is not eligible for visa-free entry, you must apply for a 48-hour transit visa (approx. $15 USD) or a 96-hour transit visa (approx. $50 USD) through a UAE-based airline like Emirates or flydubai before you arrive. Always check the latest 2026 IATA requirements for your specific passport, as visa policies for transit travelers are subject to frequent diplomatic updates.
