South Korea
Eligible Thai nationals may visit South Korea without a visa for short stays, but most travellers must obtain K-ETA approval before boarding. Apply through the official K-ETA website or app. A visa may be needed if K-ETA is refused or the purpose of travel is not covered by the exemption.
Required Documents
- ✓Valid passport (6+ months beyond intended stay)
- ✓Approved K-ETA (when required for your age and circumstances)
- ✓Return or onward travel details
- ✓Accommodation and contact information in Korea
- ✓Evidence of sufficient funds
- ✓Travel insurance (recommended)
Guidance before you apply or travel
Use only the official K-ETA website or app — avoid third-party services
K-ETA approval is not a guarantee of admission — final decision rests with immigration
The visa-exempt stay is up to 90 days — do not overstay
If K-ETA is refused, you may need to apply for a regular visa at the embassy
Check if your age group is exempt from K-ETA before applying
How to apply — step by step
- 1
Check whether your nationality requires K-ETA or is fully visa-exempt — rules vary by country and age group
- 2
If K-ETA is required, apply through the official K-ETA website (k-eta.go.kr) or mobile app at least 24-72 hours before departure
- 3
Complete the K-ETA form with passport details, travel plans, and accommodation information in Korea
- 4
Pay the K-ETA fee online using a credit or debit card
- 5
Receive K-ETA approval by email — it is linked electronically to your passport
- 6
If K-ETA is not available for your situation or is refused, apply for a regular visa at the Korean embassy or consulate in your country
Common mistakes to avoid
Using a third-party website instead of the official K-ETA site — unofficial sites charge extra fees and may provide incorrect information
Entering incorrect passport details — even a small typo can cause problems at immigration
Overstaying the 90-day visa-exempt period — this can result in fines, deportation, and future entry bans
Not having proof of onward or return travel when boarding your flight
Assuming K-ETA approval guarantees entry — the final decision is made by the immigration officer at the port of entry
Embassy & application centre
The Royal Thai Embassy in Seoul and the Korean Embassy in Bangkok handle bilateral visa matters. Thai nationals applying for K-ETA should use the official website or app. If a regular visa is needed (for work, study, or if K-ETA is refused), applications are submitted at the Korean Embassy in Bangkok (Sathorn Tai).
Frequently asked questions
Do Thai nationals need a visa for South Korea?
Thai nationals can enter South Korea visa-free for up to 90 days under the bilateral visa exemption agreement. However, K-ETA (Korea Electronic Travel Authorization) may be required before boarding depending on current regulations and your age group.
What is K-ETA and how do I apply?
K-ETA is an electronic travel authorization system. Apply through the official website (k-eta.go.kr) or mobile app. You need a valid passport, a digital photo, and travel details. Approval usually comes within 24 hours.
Can I work part-time in South Korea on a tourist visa or K-ETA?
No. The visa-exempt entry and K-ETA are for tourism, short-term business, or visiting purposes only. Working is strictly prohibited. If you wish to work, you need an appropriate work visa.
What happens if I overstay in South Korea?
Overstaying can result in fines (up to ₩30 million), deportation, and an entry ban of several years. If you need more time, apply for an extension at a local immigration office before your permitted stay expires.
