The Mongolia transit visa (category K6) allows travelers to pass through Mongolia for up to 10 days while en route to a third country. Available as an e-Visa through evisa.mn for $2.75-$25.75 USD depending on nationality, or as an embassy-issued visa for $25 USD single entry. Citizens of visa-free countries (including the US, UK, and most EU nations) do not need a transit visa at all.
What Is the Mongolia Transit Visa (K6)?
The K6 transit visa is a short-stay visa issued to travelers who need to pass through Mongolia on their way to another destination. It falls under Mongolia’s electronic visa system, launched on October 1, 2021, which introduced three e-Visa categories: K2 (tourism), K4 (sports/cultural events), and K6 (transit).
The K6 transit visa grants a 10-day stay with 150 days of validity from the date of issuance. It permits a single entry only – once you leave Mongolia, the visa cannot be reused. The e-Visa is non-extendable and non-convertible, meaning you cannot convert it to a tourist visa or extend your stay beyond 10 days while in Mongolia.
Nationals of 98-99 countries are eligible to apply for the K6 transit e-Visa. If your nationality is not on the e-Visa eligible list, you must apply for a transit visa at a Mongolian embassy or consulate instead.
Who Needs a Mongolia Transit Visa?
Whether you need a Mongolia transit visa depends on two factors: your nationality and whether you leave the international transit area.
You do not need a transit visa if:
- You hold a passport from a visa-free country (US citizens: 90 days; UK/EU citizens: 30 days until December 2026; Japan, South Korea, Turkey: 30 days)
- You remain inside the international transit area at Chinggis Khaan International Airport during a layover
- You stay on a train passing through Mongolia without exiting (e.g., Trans-Mongolian Railway)
You do need a transit visa if:
- Your nationality is not on Mongolia’s visa-free list and you are passing through Mongolia
- You plan to leave the airport during a layover
- You are breaking a train journey in Mongolia (e.g., stopping in Ulaanbaatar between connections)
- You are entering Mongolia overland as part of a multi-country trip
Citizens of countries like India, China, most African nations, and many Southeast Asian countries typically need a transit visa. Always check the current visa-free country list at en.consul.mn/visa/c/83 before traveling.

Embassy Transit Visa vs e-Visa Transit
The e-Visa is faster and cheaper for most travelers, but the embassy visa offers more flexibility for multi-entry transit.
| Feature | e-Visa (K6) | Embassy Transit Visa |
|---|---|---|
| Application | Online at evisa.mn | In person or by mail |
| Fee | $2.75 – $25.75 | $25 (single) / $50 (double) / $75 (multiple) |
| Processing | 3 working days | 2 days – 1 week |
| Stay duration | 10 days | Up to 10 days |
| Entry type | Single only | Single, double, or multiple |
| Extendable | No | No |
| Eligible countries | 98-99 countries | All nationalities |
Choose the e-Visa if your country is eligible, you need only a single entry, and you want the fastest processing. Choose the embassy visa if you need double or multiple entries, your nationality is not on the e-Visa list, or you prefer a physical visa sticker in your passport.

Mongolia Transit at Chinggis Khaan International Airport
Chinggis Khaan International Airport (UBN) is Mongolia’s main international gateway and the primary transit point for travelers passing through the country by air.
The airport, located approximately 50 km south of Ulaanbaatar in Khöshig Valley, replaced the old Buyant-Ukhaa airport in 2021. It handles all international flights to and from Mongolia.
For transit passengers:

If your layover exceeds 24 hours or you need to change terminals/airlines requiring you to exit the transit area, you will need either a transit visa or qualify for visa-free entry based on your nationality.
