How long you can stay in Korea, and which entry route a patient needs
Written by KCODI medical interpreter team · English deskUpdated · 6 min read
Korea visa how many days is the search, and for most visitors the answer is that you do not need a visa at all; your permitted stay is granted on entry. Many nationalities enter visa-free for a period commonly up to around ninety days, some need a travel authorisation first, and some need a visa arranged before flying.
Rules change, exemptions get extended and suspended, and your nationality decides everything. Nothing on this page replaces the official portals, which are linked at the bottom and are the only authoritative answer for the day you travel.
What we can give you is the patient's version: which route fits which kind of trip, what immigration actually asks, and the two things visitors get wrong, which are medication and the return ticket.
The three entry routes
| Route | Who it is for | Arrange it |
|---|---|---|
| Visa-free entry | Nationals of countries with a visa waiver, for tourism or a short visit | Before departure, if a travel authorisation is required |
| Travel authorisation (K-ETA) | Visa-waiver nationals when the requirement applies to them | Online, days before travel |
| Short-term visa | Nationals who need a visa, including for short-term treatment | At an embassy or through the visa portal |
| Medical treatment stay | Longer courses of treatment, and accompanying carers | Through the visa portal with clinic documents |
A cosmetic or dental trip of a week or two normally sits inside ordinary visitor entry. The routes that need planning are long recoveries, staged treatment and anything where a family member is coming to look after you.
What immigration actually asks
- Where you are staying. Have the hotel address written down, not only in an app you have to unlock.
- How long you are staying, and proof you are leaving. An onward or return ticket is the standard evidence.
- Why you are here. Saying you are here for medical treatment is perfectly normal and not a problem.
- The arrival and customs declaration, which Korea now handles electronically for most travellers. Doing it before landing saves you a queue.
- Your fingerprints and photo, which are taken for most adult visitors at the border.
If you have clinic paperwork, keep a copy accessible. It is rarely requested for a short visit and it takes thirty seconds to resolve a question if it is.
Medication: the rule people find out too late
Korea regulates what you can bring in, and some medicines that are ordinary at home need prior approval here. This catches people at Incheon, not on the way out.
- Bring medication in its original packaging with the label intact, and carry a doctor's letter or the prescription.
- Narcotic and psychotropic medicines, including some ADHD and strong painkiller prescriptions, may require advance approval from the Korean drug authority. Check before you fly.
- Bring only what the trip needs plus a margin, not a year's supply.
- Tell the clinic everything you take at the consultation, including the contraceptive pill and supplements. It changes anaesthesia and bleeding risk.
- Herbal preparations bought here are subject to your own country's import rules on the way home. That trap is covered in Korean herbal weight loss programmes.
When a treatment visa is worth arranging
Korea has visa categories intended for people coming specifically for medical care, including longer stays and accompanying carers. Institutions registered to treat foreign patients can normally issue the supporting documents.
- Treatment expected to run beyond your visa-free allowance, such as staged reconstruction or long rehabilitation.
- A carer or family member travelling with you whose nationality needs a visa.
- Treatment at a hospital that asks for the documentation as part of admission.
- A second stage a few months later, where it is easier to plan the paperwork once.
- Anything where you would rather not be counting days against an entry stamp while you are recovering.
Whether your treatment needs that much time is a clinical question first. Work out the schedule in how many days you need in Korea, then decide the paperwork.
Arriving: the practical half hour
Incheon and Gimhae are efficient, and the friction is almost always paperwork you could have done on the plane or at home.
- Complete the electronic arrival and customs declarations before landing where they are available. The queues for the paper version are longer.
- Have the clinic or hotel address in writing, and a screenshot of your booking that does not need mobile data.
- Keep the travel authorisation confirmation with your boarding pass, because the airline checks it before immigration ever sees you.
- Declare medication honestly if the form asks. A labelled box and a prescription letter turn a question into a nod.
- Buy a data plan before you leave the airport, so your interpreter can reach you the moment anything moves.
If you are arriving the night before a fasting appointment, remember the flight itself is part of the fast. Ask the clinic what you may drink on the way in, because long-haul dehydration and a blood draw at nine in the morning are a bad combination.
Overstaying, extending and the sensible margin
Overstaying is treated seriously and can affect future entry. If your recovery runs long, that is a matter to raise with the immigration office before the permitted date, not after.
The simpler protection is a margin. Build the trip backwards from the last clinic appointment, keep spare days, and do not plan a schedule that uses every hour of your permitted stay. What that costs is set out in budgeting a treatment trip.
If you want the appointments mapped before you commit to dates, clinic matching takes about two minutes, or meet the interpreters who would be handling the calls.
