Mongolia entry requirements for Thailand passport holders
Thai passport holders can enter Mongolia without a visa for stays up to 30 days. This visa-free arrangement applies to tourism and business visits in 2026. Ensure your passport meets the entry requirements and have your return ticket ready.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| Valid passport Must be valid for at least 6 months beyond your departure date from Mongolia | Your passport needs at least 6 months of validity remaining from the day you leave Mongolia. Airlines check this at check-in — if your passport expires sooner, you'll be denied boarding. | Required |
| Return or onward ticket Proof of departure from Mongolia | Immigration officers at Ulaanbaatar's Chinggis Khaan International Airport routinely ask for a confirmed onward or return ticket. Have a printed or digital copy of your flight booking ready — they may deny entry if you can't show one. | Required |
| Proof of accommodation Hotel booking or host invitation | Carry a printed or digital hotel reservation for your entire stay. If staying with friends or family, have their address and phone number written down — border officers occasionally ask for it. | Recommended |
| Proof of funds Evidence of sufficient money for your stay | Officers may ask how you'll support yourself during the trip. Have a bank statement or credit card showing at least 20,000 THB equivalent (roughly 1,500,000 MNT) ready — cash, card, or a combination works. | Recommended |
