Korea's entry system for tourists has three separate, easily confused layers: the K-ETA (a pre-travel authorization), the e-Arrival Card (a landing declaration), and the visa itself (which most short-term tourists don't need at all, thanks to visa-waiver agreements). Mixing these three up is the single most common source of confusion for first-time visitors — including a fair number of people who assume "I don't need a visa" also means "I don't need to do anything before I fly," which isn't always true. This guide walks through how each piece works, who needs what, and — because these are exactly the kind of rules that shift with little warning — where to check the current requirement for your specific passport before you travel.
The three-layer system, at a glance
| Layer | What it is | Who needs it |
|---|---|---|
| Visa-waiver access | An agreement letting citizens of certain countries enter for short tourist stays without applying for a traditional visa | Most Western, EU, and many Asian passport holders — but not everyone |
| K-ETA (Korea Electronic Travel Authorization) | A pre-travel electronic screening, similar in concept to the US ESTA — not a visa, but required before boarding | Visa-waiver travelers, unless a temporary exemption is currently in effect for their nationality |
| e-Arrival Card | A trip-specific digital landing declaration, replacing the old paper form | Most arriving travelers who don't already hold a valid K-ETA |
In plain terms: your passport determines whether you can skip the visa. Your K-ETA status (whether required, exempt, or voluntarily held) determines what you do before boarding. And the e-Arrival Card is a separate, per-trip step for whoever isn't covered by a valid K-ETA.
Do you need a K-ETA?
The K-ETA (Korea Electronic Travel Authorization) is run by Korea's immigration service under the Ministry of Justice. It's a mandatory pre-screening for citizens of visa-waiver countries — technically required for most of them — but Korea has periodically introduced temporary exemptions for a long list of nationalities (including, at various points, the US, Canada, the UK, most of the EU, Australia, New Zealand, and several Asian countries) as part of tourism-promotion pushes. These exemptions have been extended more than once, most recently through the end of 2026 at the time of writing — but "at the time of writing" is exactly the caveat that matters here.
- If your nationality is currently exempt, you don't need to apply for a K-ETA at all — you can board and land without one.
- You can still apply voluntarily even if exempt. A valid K-ETA is good for three years (or until your passport expires, whichever comes first), and holding one means you skip the e-Arrival Card on every subsequent trip within that window.
- If your nationality isn't currently exempt, the K-ETA is mandatory — you cannot obtain it on arrival, and airlines will generally check before allowing you to board, since they're liable for travelers who get turned back.
Applications go through the official K-ETA site (linked below), typically require a passport-style photo and basic trip details, and are usually processed within a day or two, though it's worth applying at least 72 hours before departure to leave room for delays or a request for more information.
The e-Arrival Card
Since the system moved fully digital, most travelers who don't already hold a valid K-ETA need to submit an e-Arrival Card before landing — a trip-specific declaration (not multi-year like the K-ETA) completed online in the days immediately before arrival. This replaced the paper arrival card that used to get handed out on the plane. A few categories are exempt from filing it separately, including registered residents of Korea and travelers who already hold a valid K-ETA (since the K-ETA application already captures the same information).
Practically: if you're a first-time tourist from a K-ETA-exempt country, this is very likely the one form you actually need to fill out before you fly — plan on doing it within the specific window (typically a few days before arrival) that the official site specifies, not weeks ahead.
How long can you actually stay?
Visa-free stay length depends on the specific bilateral agreement between Korea and your country, not on the K-ETA — the K-ETA's three-year validity is a separate thing from how many days you're allowed to stay per visit. In broad terms, permitted stays cluster around a few common lengths — roughly 90 days for many Western and EU passport holders, shorter windows around 30 days for a number of other countries, and a small number of unusual cases (Canada has historically had one of the longest visa-free allowances of any nationality). These specifics vary by country and do change, so this page won't print a definitive table you'd be tempted to rely on — Korea's official visa portal lets you check the exact permitted stay for your specific nationality.
Whatever your allowance, it resets per visit, not per calendar year, and there's generally no simple way to extend a visa-free stay from inside Korea — a same-day "visa run" (leaving and re-entering to reset the clock) is not officially sanctioned and immigration officers can refuse re-entry if they suspect that's what you're doing.
If you need an actual visa
Travelers from countries without visa-waiver access, or anyone planning to work, study, or stay longer than the visa-free allowance, need to apply for the appropriate visa category through a Korean embassy or consulate before departure — it can't be arranged on arrival. Processing times vary by consulate and season, so start well ahead of your planned travel dates rather than assuming a quick turnaround. Hi Korea, the government's portal for foreign residents, is the main resource for visa categories, extensions, and requirements once you're looking beyond a simple tourist stay.
What to have ready at the airport
- Passport validity — many airlines apply a general international standard of six months' remaining validity beyond your stay, though this is more of an airline check-in norm than a universal Korean government requirement; either way, it's worth having the buffer.
- Proof of onward or return travel — commonly requested at check-in or immigration, especially for one-way or long-stay tickets.
- Your K-ETA approval or e-Arrival Card confirmation — save a screenshot or PDF; don't rely on having signal to pull it up at the airport.
- Accommodation details — occasionally requested at immigration, so have your first night or two of bookings accessible.
What actually happens at immigration
After landing, arriving travelers follow signage to immigration, where an officer reviews your passport and entry documentation. This is also the point where the final admission decision is genuinely made — an approved K-ETA doesn't guarantee entry on its own, though in practice straightforward tourist arrivals are routine and fast. After immigration, you'll collect baggage and pass through a customs checkpoint — a declaration is required even if you have nothing to declare, and families traveling together can typically file one combined form.
Two special cases worth knowing about
- Jeju Island operates its own separate visa waiver program, distinct from the mainland K-ETA system, allowing broader nationality access for visits confined to the island. If your trip includes Jeju alongside Seoul, this is worth checking specifically rather than assuming your mainland entry status automatically covers it.
- APEC Business Travel Card holders from participating economies get streamlined entry for business trips of up to 90 days, bypassing some of the standard process — relevant if you're traveling for work rather than tourism.
Common mistakes to avoid
- Assuming "visa-free" means "nothing to do before flying." It usually still means a K-ETA and/or e-Arrival Card, unless you fall under a specific current exemption.
- Applying for K-ETA at the airport. It can't be done on arrival — it has to be approved before you board, and airlines check.
- Confusing K-ETA's three-year validity with your permitted stay length. They're unrelated; a valid K-ETA doesn't extend how many days you can stay on any single visit.
- Checking requirements months ahead and not rechecking closer to departure. Given how often this has changed recently, a status you confirmed six months ago may not reflect the current rule.
- Overstaying. Even a short overstay can mean fines and can complicate future entry to Korea; if your plans change, it's worth understanding the extension process through Hi Korea well before your permitted stay runs out, rather than after.
Official sources to verify current rules
Rules and country lists here are the kind of thing that shift with little notice, so treat the following as your primary sources rather than this page or any third-party blog:
- K-ETA official site — applications, current exemption status, and eligibility by nationality.
- Korea Visa Portal — visa-free stay length and visa requirements by nationality.
- e-Arrival Card official site — the digital landing declaration.
- Hi Korea — visa categories, extensions, and immigration contact details for anyone beyond a simple tourist stay.
- Your nearest Korean embassy or consulate — the authority on your specific passport's requirements, and the only place to apply for a full visa.
