Introduction
If you’re planning to travel to Korea for surgery, fertility treatment, cancer care, or a multi-stage procedure at one of Seoul’s major university hospitals, the visa question comes up almost immediately. Many patients from Southeast Asia and China don’t actually need a separate medical visa for short visits — but for longer treatment plans, choosing the wrong visa category can mean a forced exit and re-entry mid-treatment.
This guide covers both Korea Medical Visa categories — who needs each one, and how the process works in 2026.
Do You Even Need a Medical Visa?
Not every international patient needs a C-3-3 or G-1-10 visa.If your nationality has visa-free or K-ETA access, a standard tourist entry often covers short visits. This includes consultations, minor dermatology, and single-session treatments.
The dedicated medical visa categories exist for a more specific situation: when your hospital needs to formally sponsor your stay, or when your treatment timeline runs longer than a standard tourist stay allows.
For Southeast Asian patients specifically: K-ETA rules vary significantly by country. As of 2026, Korea has extended a temporary K-ETA exemption through December for a specific list of nationalities. But the list doesn’t treat every country the same way. Some Southeast Asian nationals are exempt only as part of registered group tours, while others must apply individually regardless of the exemption period. Since this changes from country to country and updates periodically, always verify your specific nationality’s current status before booking flights, rather than relying on a general “Asia is exempt” assumption.
C-3-3: The Short-Term Medical Visa
The C-3-3 is the most common Korea Medical Visa category, and the one most international patients will use.
Who it’s for: Patients coming for treatment or recuperation lasting up to 90 days, plus one accompanying caregiver per patient.
What you need:
- Invitation or treatment confirmation from a Korean hospital registered to treat international patients
- Proof of financial capacity to cover treatment and living costs
- Passport, application form, and a recent passport-style photo
- Return travel documentation
Processing time: Typically a few business days, though this varies by consulate and embassy workload. In many jurisdictions, you’ll need to apply through an appointed visa agent or travel agency rather than submitting in person.
Validity: Generally valid for a single stay of up to 90 days. If your treatment timeline is genuinely short — a single surgery and recovery window, a course of fertility treatment that wraps within three months — this is almost always the right category.
G-1-10: The Long-Term Treatment Visa
The G-1-10 exists for patients whose treatment realistically can’t be completed in 90 days.
Who it’s for: Patients undergoing extended or multi-stage treatment — cancer therapy, complex orthopedic recovery, sequential reconstructive procedures, or ongoing monitoring that requires repeated visits to the same hospital. Caregivers accompanying these patients typically apply under the same category.
What you need: Largely the same documentation as C-3-3, plus evidence that your treatment plan genuinely requires more than 90 days — a treatment schedule or letter from your hospital is usually the deciding document.
Validity: Can extend up to one year, and in practice this is often the visa patients convert into mid-treatment, after starting on a C-3-3 and realizing recovery is taking longer than planned.
Switching From C-3-3 to G-1-10
This is more common than people expect. A patient enters Korea on a C-3-3 expecting a 90-day treatment window, but their hospital determines mid-treatment that recovery will take longer. In this situation, contacting the local immigration office before the current visa expires — with a supporting letter from the treating physician — is the standard path to converting to G-1-10 or extending the existing visa. Don’t wait until the visa lapses — have that conversation while it’s still valid.
Choosing between these two Korea Medical Visa categories usually comes down to one question: how long will your treatment realistically take?
A Quick Comparison
| C-3-3 | G-1-10 | |
|---|---|---|
| Stay duration | Up to 90 days | Up to 1 year |
| Best for | Single procedures, short recovery | Multi-stage treatment, cancer care, extended rehab |
| Caregiver visa | Yes, accompanying caregiver eligible | Yes, same category |
| Can convert from C-3-3? | — | Yes, with hospital documentation |
Practical Tips Before You Apply
Getting your Korea Medical Visa application right the first time saves weeks of back-and-forth with immigration.
Confirm your hospital is registered for international patients. Korea’s major university hospitals — Asan Medical Center, Samsung Medical Center, Seoul National University Hospital, Severance Hospital, and Seoul St. Mary’s Hospital — all have dedicated international patient centers that issue the documentation your visa application needs. Smaller clinics may not be registered, which can complicate the visa process even if the treatment itself is straightforward.
Get your invitation letter early. Visa processing can’t start until your hospital issues a confirmation, so this should be one of the first things you request once your treatment plan is set, not something arranged the week before travel.
Don’t assume your K-ETA exemption covers a medical visa scenario. K-ETA exemptions are designed around general tourism, business, and family visits. If your treatment plan pushes past a short visit, you’ll likely need to apply for C-3-3 or G-1-10 separately, even if your nationality is otherwise exempt from K-ETA for tourism purposes.
Work through a medical coordinator if possible. Many hospitals and patient-facilitation services in Korea help international patients navigate paperwork. This isn’t required, but it significantly reduces the chance of a documentation gap delaying your visa.
