Most guides to medical travel in Korea are written for the patient. This one is for the person beside them — the spouse who took unpaid leave, the daughter who flew in from Lagos or Lima or Riyadh, the friend who speaks the most English in the family. Your job is real, it is underrated, and it has its own logistics, paperwork, and pitfalls.
This guide is for companions and caregivers traveling to Korea from anywhere — West Africa, the Gulf, Southeast Asia, the Americas, Europe. The hospital does not change based on where you flew from, but your visa route and your budget might. We will keep figures as approximate ranges; exchange rates and prices move.
This is general planning information, not medical or legal advice. Confirm visa rules with the Korean diplomatic mission for your country and clinical questions with the treating hospital.
First: Are You On the Visa, or Just Tagging Along?
This is the single most expensive mistake companions make — assuming they can sort their entry “later.”
There are two main tracks, and which one applies depends on how long the patient stays.
Short stays: the C-3-3 medical tourism visa
The C-3-3 is Korea’s short-term medical tourism visa, valid for up to 90 days. Crucially, it is not only for the patient — a registered companion or caregiver can be issued a C-3-3 tied to the same treatment plan.
A few things that trip people up:
- It requires a hospital invitation letter on official letterhead, naming the patient, the treatment, the dates, and the estimated cost. You cannot apply on a generic tourist basis and convert.
- The mission wants bank statements showing a steady balance over roughly the last six months — enough to cover the quoted treatment plus living costs for the patient and any companions. A sudden large deposit two weeks before applying reads as a red flag, not reassurance.
- Processing is commonly 5–10 business days for clean cases, and the visa is valid for three months from issue.
As of a December 2025 policy update, the eligible companion scope was widened. Previously only a spouse or first-degree relative (parent or child) could be registered. The expansion now formally includes siblings and designated caregivers — a meaningful change for patients whose only available support is a brother, sister, or a hired aide rather than a spouse.
Long stays: the G-1-10 treatment visa
If the patient needs more than 90 days — common for cancer regimens, rare-disease treatment, or long rehabilitation — the relevant category is the G-1-10 long-term treatment visa, valid up to one year.
Family members who intend to nurse the patient typically apply in the same G-1-10 category, supplying proof of relationship: marriage certificate, family relationship certificate, birth certificate. You will also need a medical opinion from the institution justifying the long stay, plus evidence you can cover treatment and living expenses for the whole party.
Operator note: if there is any real chance the stay runs past 90 days, raise G-1-10 before you fly. Switching from C-3-3 to G-1-10 inside Korea is possible but document-heavy, and you do not want to be assembling apostilled certificates from your home country while sitting in a Seoul recovery apartment.
The Korea Health Industry Development Institute (KHIDI), the government body under the Ministry of Health and Welfare (MOHW) that oversees registered medical-tourism providers, is the reference point for how invitations and the visa pathway are supposed to work. A clinic that cannot speak fluently about KHIDI registration is a clinic to question.
The Korean Hospital Will Not Expect You to Sleep on a Cot
Companions from many countries arrive braced to camp in the ward. Korea’s inpatient culture is different, and understanding it early saves a lot of confusion.
The guardian (보호자) system
Korean hospitals operate around a guardian — boho-ja (보호자) — the designated family contact who signs consents, receives the doctor’s updates, and is the point person for decisions. As a companion, you are very likely the guardian. That is a role with real responsibility, not a visitor’s badge.
You do not have to be there 24/7 — and often shouldn’t be
Here is the part that genuinely relieves exhausted families: you are not expected to provide round-the-clock bedside care yourself. Korea has a well-established system of professional caregivers — ganbyeong-in (간병인) — dispatched by caregiver agencies (they are not hospital staff). You arrange one through the nurse’s station of the ward.
Approximate cost: ₩85,000–₩125,000 per day (very roughly USD 60–95), varying by region and by supply and demand. Many large hospitals — for example, Seoul National University Hospital and the Catholic University hospitals — have formal processes for requesting one.
For a companion who has a job back home, other children to mind, or simply a body that needs sleep, a ganbyeong-in for the acute inpatient days is not a luxury. It is what lets you be useful for the weeks that matter — discharge, follow-ups, the long tail of recovery.
Where You’ll Actually Live: The Clinic Districts
The patient’s hospital district decides where you stay, because you will be commuting to it daily once treatment moves to outpatient follow-up.
The center of gravity for international patients is southern Seoul — Gangnam, Apgujeong, and the Sinchon area on the other side of the river — clustered around major hospitals and clinics. Big general hospitals like Gangnam Severance and the CHA network sit within a short drive of dense lodging.
Rough nightly ranges for medical-traveler accommodation:
- Budget rooms / officetels: from around ₩60,000/night (~USD 45).
- Serviced apartments near Gangnam clinics: roughly ₩200,000/night (~USD 150), often with a kitchenette — which matters enormously when the patient is on a restricted diet or you are cooking to save money over a long stay.
- Premium hospital-adjacent suites: ₩300,000–₩800,000/night for the high end.
What to actually prioritize as a companion, in order:
- A kitchenette. Recovery diets, halal or other dietary needs, and budget control all run through the ability to cook.
- Walking distance or one clean subway/taxi hop to the hospital. You will make this trip more times than you expect, sometimes with a patient who tires fast.
- An elevator and step-free entry. Post-procedure mobility is the constraint people forget when booking the cute place up a flight of stairs.
Some hospital networks run dedicated medical-tourism accommodation with nurse availability, transport to follow-ups, and rooms adapted for limited mobility. Ask the international patient center whether this exists before you book independently — it can fold a lot of separate logistics into one.
Money, SIMs, and the Boring Things That Derail Trips
Cash, cards, and the deposit
Korea is card-friendly, but international cards still hiccup at some smaller clinics and pharmacies. Carry a reasonable cash buffer in won for incidentals. Be ready for a hospital to request a deposit against the estimate before admission — clarify with the international office in writing what is due, when, and in what currency.
Connectivity from the moment you land
Pick up a SIM or eSIM at Incheon International Airport (ICN) on arrival, or order an eSIM before departure. As the guardian, you are the one fielding calls from the ward and the coordinator; a dead phone on day one is a genuinely bad start. Save the hospital’s international patient center number and your coordinator’s mobile before you leave the airport.
Translation and the interpreter gap
Larger international-patient hospitals provide interpreters for English and often Arabic, Russian, Chinese, and Mongolian — but interpreter coverage can thin out for evening shifts, pharmacy counters, and outside the hospital. Keep a translation app loaded, and confirm in advance which languages the hospital actually staffs versus which it expects you to bring.
Aftercare you carry home
Before discharge, get from the doctor, in writing and ideally in English: the diagnosis, the procedure performed, medications with generic names and dosages, and the follow-up schedule. Your home doctor will need this, and “the Korean pharmacy label” is not a substitute. Ask whether follow-up can be done by telemedicine once you are home, and how to reach the team if something changes.
Look After the Caregiver, Too
The unspoken pain point of medical travel is that the companion runs themselves into the ground. You are managing a sick person, a foreign system, money pressure, and your own jet lag, often while being the family’s only contact back home.
Two practical defenses:
- Off-load the acute inpatient nights to a ganbyeong-in so you arrive at the decisions clear-headed.
- Build in one genuinely off-duty block per week. Seoul rewards it — but even a quiet afternoon counts. A collapsed caregiver helps no one.
Key Takeaways
- Sort your own entry before you fly. Companions can be registered on the patient’s C-3-3 (short stay) or G-1-10 (long stay); the December 2025 update added siblings and designated caregivers to the eligible scope. Decide the visa track on expected length of stay, not convenience.
- The hospital invitation letter and six months of steady bank statements are the load-bearing documents. Don’t improvise them.
- You are likely the guardian (보호자) — a real role — but you do not have to provide 24/7 care. A professional ganbyeong-in runs roughly ₩85,000–₩125,000/day and is arranged through the ward nurse’s station.
- Stay in or near the clinic district (Gangnam / Apgujeong / Sinchon). Budget rooms from ~₩60,000/night, serviced apartments ~₩200,000/night; prioritize a kitchenette, short commute, and step-free access.
- Confirm deposits in writing, get a SIM at ICN, and leave with an English discharge summary and a follow-up plan.
- KHIDI / MOHW registration is the mark of a legitimate provider — and a question the hospital’s international patient team should answer without hesitation.
