Korea Medical Visa (C-3-3): A Step-by-Step Guide for International Patients (Complete Guide)

22 hours ago
5 min read

To receive medical treatment in South Korea, most international patients use either a short-term C-3-3 medical visa for stays up to 90 days or a longer-term G-1-10 visa for extended treatment and recovery — though visa-free entry may suffice for some short, minor procedures.

Most "Korea medical visa" articles are vague, outdated, or copied from each other, and immigration rules change. This guide gives international patients a clear framework current as of 2026: which visa fits your situation, the medical documents that matter, how to apply step by step, and why applications get delayed — while pointing you to the official sources you must confirm before booking. Always verify current requirements with HiKorea and your nearest Korean embassy or consulate, as rules and processing times change.

Do you even need a medical visa?

Not every patient needs a dedicated medical visa. Nationals of many countries can enter Korea visa-free or with an electronic travel authorisation (K-ETA) for short tourism stays, which can cover very minor, quick procedures. However, if your treatment is substantial, requires follow-up, or your stay approaches or exceeds 90 days, a medical visa is the appropriate and safer route. Entering as a tourist for major surgery can create problems with documentation, insurance, and any needed extension, so confirm your case with the embassy.

C-3-3 vs G-1-10: which applies to you

South Korea offers two main medical pathways. The C-3-3 is a short-term medical visa, generally for stays up to 90 days, suited to most cosmetic or single-treatment trips. The G-1-10 is a longer-term medical-treatment-and-recovery visa for patients needing extended or serious care beyond 90 days, often arranged through a registered medical institution or attracting agency. Your treatment type, expected length of stay, and the hospital registration status determine which is correct, so ask your clinic and the embassy directly.

What most guides leave out: the documents that actually get you approved

The detail that decides many applications is the medical paperwork, not the form itself. Consulates typically want proof that a recognised Korean medical institution will treat you: a confirmation or appointment letter or treatment plan from the hospital, and often documentation that the institution is registered to attract international patients with KHIDI. You will also need to show you can fund the treatment and stay. Thin or generic documentation is a common reason for delay; a clear hospital letter and proof of funds strengthen your case.

Step-by-step: how to apply

In broad terms: (1) choose and contact a Korean hospital or a registered medical-tourism agency and obtain a treatment plan or appointment confirmation; (2) gather your documents, including passport, photo, application form, financial proof, and the hospital paperwork; (3) apply at the Korean embassy or consulate in your country, or through an authorised agency, paying the visa fee; (4) wait for processing, which varies by country and season; and (5) travel once approved. Some patients use the official visa portal where available. Confirm the exact channel for your country.

Required documents checklist

Requirements vary by nationality and visa type, but applicants are commonly asked for: a valid passport and a recent photo, the completed application form, a confirmation or medical appointment letter from the Korean hospital, a treatment plan, proof of sufficient funds (such as bank statements), proof of accommodation, and sometimes a document showing the hospital is registered to host international patients. For G-1-10, additional medical records may be requested. Treat this as a starting point and confirm the current list with the embassy.

Bringing a companion or caregiver

Patients who need support during treatment and recovery can often bring a caregiver. A companion may apply on a matching short-term basis with the patient, while longer-term care can involve a dedicated accompanying-caregiver status tied to the patient G-1 visa. Relationship and financial documentation is usually required. Because companion rules are detailed and change, confirm the exact category and paperwork for your situation with the embassy before you both book travel.

Common reasons applications are delayed or refused

Frequent issues include incomplete or inconsistent documents, an unclear or missing hospital treatment plan, insufficient proof of funds, choosing the wrong visa category for the length or seriousness of treatment, or applying too close to the travel date. Using a hospital or agency registered with KHIDI, submitting a clear treatment plan, and applying well in advance reduce these risks. If refused, the consulate may indicate what was missing so you can reapply.

After you arrive: extensions and compliance

If your recovery runs longer than expected, extensions may be possible through the immigration office (often handled via HiKorea), typically requiring updated medical documentation from your treating hospital. Keep your treatment records, comply with the conditions of your visa, and avoid overstaying, which can affect future entry. Your hospital international patient coordinator can usually help with extension paperwork.

Frequently Asked Questions

Can I just come on a tourist visa for surgery?

For very minor, quick procedures within a short visa-free or K-ETA stay, some patients do. For substantial surgery, follow-up, or longer stays, a medical visa (C-3-3 or G-1-10) is the appropriate route. Confirm your specific case with the Korean embassy.

How long does the medical visa process take?

Processing times vary widely by country, season, and visa type, from a few days to several weeks. Apply well before your planned treatment and confirm current timelines with your embassy or the official visa portal.

Do I need the hospital to arrange my visa?

You typically apply yourself or through an authorised agency, but you do need documentation from a Korean medical institution — such as a treatment plan or appointment letter — and ideally one registered with KHIDI to attract international patients.

What if my treatment takes longer than 90 days?

A stay beyond 90 days generally calls for the G-1-10 medical-treatment visa rather than the short-term C-3-3, or an extension if you are already in Korea. Confirm the correct path with the immigration office or embassy.

Plan your trip with verified information

Use this framework to identify the likely visa for your treatment, then confirm every detail with official sources before booking. Choose a KHIDI-registered hospital, obtain a clear treatment plan, and apply early. If you would like help coordinating care in Korea, contact a registered clinic or medical-tourism coordinator.
