The general shape
Korea operates a visa-waiver program for passport holders from a long list of countries, allowing short tourist stays without a traditional visa. Separately, Korea has at various times required visa-exempt travelers to register in advance through an electronic travel authorization system before boarding their flight. Whether that requirement is currently active, and for which nationalities, has changed more than once in recent years — including temporary suspensions aimed at boosting tourism.
What tends to stay consistent
- You'll generally need a passport valid for a set period beyond your stay (commonly six months, but confirm the current requirement).
- Proof of onward or return travel is commonly requested at check-in or immigration.
- Airlines will generally check that you meet entry requirements before letting you board, since they're liable for turning back travelers who don't.
If you need a full visa
Travelers from countries without visa-waiver access, or those planning longer stays, work, or study, will need to apply through a Korean embassy or consulate in advance. Processing times vary, so start well before your planned travel dates.
Where to check
The most reliable sources are Korea's official immigration authority website and the website of your nearest Korean embassy or consulate. Airline booking sites and government travel-advisory pages for your own country are good secondary checks.
