Entry requirements
| Requirement | Details | Status |
|---|---|---|
| Visa application Apply for a visa before travel | You need a visa to enter South Korea. Apply at the South Korean embassy or consulate in Thailand, or use the eVisa portal at visa.go.kr. Processing takes 5–10 working days, so apply at least 2 weeks before your flight.Apply for eVisa | Required |
| Valid passport Must be valid for entire stay | Your passport must be valid for the full duration of your stay in South Korea. No 6-month validity rule applies, but airlines may still check for it — carry a copy of your visa approval just in case. | Required |
| Return or onward ticket Proof of departure from South Korea | Immigration officers routinely ask for a return or onward ticket at Incheon Airport. Have a printed or digital copy of your flight itinerary ready — they check this before stamping your entry. | Required |
| Proof of accommodation Hotel booking or host invitation | Have a hotel reservation or a letter from your host ready. Immigration may ask where you're staying, especially if you're on a tourist visa. A simple booking confirmation works. | Recommended |
| Proof of funds Show you can support yourself | Carry bank statements or a credit card showing at least 20,000 THB or equivalent. Immigration rarely asks, but if they do, you need to show you have enough for your stay. | Recommended |
No visa-on-arrival — apply well in advance
Thai passport holders cannot get a visa at the airport. Submit your application at least 2-3 weeks before departure. Last-minute trips are risky.
Keep digital copies of everything
Save screenshots of your visa approval, return ticket, and accommodation on your phone. If your phone dies, a printed backup is even better.
