As a Mongolian passport holder, you'll be pleased to know that travel to Taiwan is visa-free, allowing for stays of up to 90 days without the need for a visa fee, offering significant flexibility for your visit. This generous entry policy makes planning your trip straightforward, especially since many direct flights from Ulaanbaatar to Taipei operate daily, typically taking around 6-7 hours. While you won't encounter visa complexities, remember that Taiwan uses the New Taiwan Dollar (TWD) as its currency, so be sure to make those exchanges before you depart or upon arrival, and consider that Taiwanese Mandarin is the official language, though English is understood in major tourist areas.
