Mongolia entry requirements for South Korea passport holders
South Korean passport holders can visit Mongolia without a visa for stays up to 90 days. This policy has been in place for years and continues through 2026. Ensure your passport is valid for at least 6 months from your entry date.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| Valid passport Must be valid for the duration of your stay | Your passport needs to be valid for the entire time you're in Mongolia. Airlines at Incheon check this before boarding — if your passport expires before you leave Mongolia, you'll be denied boarding. | Required |
| Return or onward ticket Recommended to show at immigration | Immigration officers at Chinggis Khaan International Airport routinely ask for proof of onward travel. Have a printed or digital copy of your return or next-destination ticket ready — they'll check the date matches your 90-day visa-free stay. | Recommended |
| Proof of accommodation Recommended to have ready | Hotel bookings or a letter of invitation from a host in Mongolia can speed up the immigration process. Officers rarely demand it, but having it avoids delays if they ask. | Recommended |
| Proof of funds Recommended to show if asked | Carry enough cash or a credit card to cover your stay — around $50–$100 USD per day is a safe benchmark. Immigration rarely checks, but budget airlines flying into Mongolia may ask at check-in. | Recommended |

Transiting through Mongolia

Health & vaccines for Mongolia
Mongolia's high altitude (especially in the Gobi and mountainous regions) can cause altitude sickness; acclimatize gradually.
Contaminated food and water can cause traveler's diarrhea; drink bottled or boiled water and eat thoroughly cooked food.
Ulaanbaatar has severe air pollution in winter; those with respiratory conditions should take precautions.
Based on CDC and WHO guidance. Consult a travel medicine clinic 4–6 weeks before departure for personalised advice.
