Do you need a medical visa for treatment in Korea?
Visa-free entry, K-ETA, the short-term medical visa and the long-term treatment visa — which question decides which one applies to you, and what the hospital has to provide.
Whether you need a medical visa depends on two things: your nationality, and how long treatment and recovery will keep you in Korea. The procedure itself matters much less than people think.
Verify before you rely on this: Visa categories, visa-free lists and K-ETA exemptions are set by Korea's Ministry of Justice and change — sometimes temporarily, for a tourism campaign. Everything below is the general structure. Confirm your own case on HiKorea or with the Korean embassy in your country before booking flights.
Step 1: can you enter without a visa?
Citizens of many countries can enter Korea for a short stay without a visa, usually after obtaining an electronic travel authorization (K-ETA) online unless their nationality is temporarily exempt from it. If treatment and recovery fit inside the short stay you are allowed, many visitors in this group never apply for a medical visa — but carry the hospital's appointment confirmation in case an immigration officer asks the purpose of your visit.
Step 2: if you need a visa, which one
| Category | Intended for | Typical length |
|---|---|---|
| C-3-3 (medical tourism, short-term) | Treatment, checkups and recovery that fit in a short stay | Up to 90 days |
| G-1-10 (medical treatment, long-term) | Treatment that needs a longer stay — e.g. cancer care, long rehabilitation | Over 90 days, as treatment requires |
A companion — usually a family member or caregiver — can often apply in a related category. Ask the hospital's international centre early; patient and companion documents are normally prepared together.
What the hospital usually has to give you
- A letter or certificate confirming the appointment or treatment plan.
- For some nationalities and categories, a document from a hospital or agency registered with the government's foreign-patient programme.
- An estimate of the treatment period, which is what justifies the length of stay you apply for.
You will normally also need proof you can pay — bank statements or a deposit receipt — and a passport valid well beyond your planned stay.
From my own visits: International centres at large hospitals issue visa letters routinely and know which form your embassy expects, but they work through a queue. Ask for the letter in the same email where you confirm the date, not afterwards. A week of waiting for paperwork is common, and it is the week nobody plans for.
When treatment runs longer than planned
Extensions are applied for at an immigration office inside Korea, before your current permitted stay ends, with a doctor's statement that treatment is continuing. Overstaying — even by a few days, even for a medical reason — causes problems for future entry. If your surgeon says recovery needs longer, start the extension that same week.
Do not accept a visa arranged by a broker who asks you to state a different purpose of visit, and do not work or study on a medical visa. Misstating the purpose of entry is a much bigger problem than applying correctly.
