Medical Visa for Korea: Step-by-Step Guide for US Citizens (2026)
One of the most common questions we get: “Do I need a visa to get medical treatment in Korea?” For most of our patients, the answer is simpler than you’d expect.
If you’re a US, UK, EU, Canadian, or Australian citizen: You can enter Korea visa-free for up to 90 days. That’s more than enough time for a health checkup (3 days), dental work (1-2 weeks), plastic surgery and recovery (2-4 weeks), or even a full course of cancer treatment.
If you need a visa (Russian citizens, some Middle Eastern nationals, and citizens of countries without visa-free agreements): Korea offers the C-3-3 medical tourism visa, specifically designed for patients and their companions.
This guide covers both scenarios, plus exactly what documentation you need and how InKoreaNow helps with the process.
When You DO Need a Visa: The C-3-3 Medical Tourism Visa
Who Needs It
The C-3-3 visa is primarily needed by:
- Russian citizens: visa required for Korea
- Saudi Arabian citizens: visa required
- Citizens of countries without visa-free agreements with Korea
- Any patient who needs to stay longer than 90 days (for extended treatment)
C-3-3 Visa Details
| Detail | Information |
|---|---|
| Visa type | C-3-3 (Medical Tourism) |
| Duration of stay | 30 or 90 days |
| Validity | 3 months from issuance (must enter Korea within this period) |
| Processing time | Approximately 4 working days (can vary 2-4 weeks) |
| Application method | Through designated travel agent (personal submission not allowed in most countries) |
Required Documents
- Passport: valid for at least 6 months beyond your intended stay
- Completed visa application form
- Recent passport photo: 3.5 x 4.5 cm
- Medical institution confirmation letter: official certificate of admission from a MOHW-registered Korean medical institution (hospital appointment confirmation)
- Proof of sufficient funds: bank statement showing ability to cover treatment and living costs
- Return flight itinerary: evidence of intended departure from Korea
- Additional for some nationalities: TB test from a designated hospital (within 3 months)
Caregiver/Companion Visa
Accompanying family members (spouse, parents, children) can apply under the same C-3-3 category as a caregiver. They need:
- Their own passport and application
- Proof of relationship to the patient
- The patient’s medical institution confirmation letter
Visa Extensions
If your treatment requires more time than your initial visa allows, extensions are possible from within Korea:
- Apply at the local Immigration Office at least 1 week before your visa expires
- Provide a medical certificate from your attending physician confirming ongoing treatment
- Extension is typically granted for the duration of your treatment plan
Common Questions About Entry & Visas
I’m American. Can I just show up and go to a hospital?
Technically, yes. As a US citizen, you can enter Korea visa-free and visit any hospital. However, we strongly recommend booking your hospital appointment in advance through InKoreaNow. Walk-in patients may face long waits, language barriers, and may not get the specialist or package they want. Pre-booking ensures your screening or treatment is ready when you arrive.
What if I need treatment for more than 90 days?
If you’re a visa-free nationality but your treatment plan exceeds 90 days (possible for cancer treatment, extended rehabilitation, or multiple surgical stages), you have two options:
- Apply for a C-3-3 medical visa before travel (allows for longer stays)
- Enter visa-free and convert to a medical visa within Korea (apply at Immigration Office before your 90 days expire)
We recommend option 1 for predictability.
Can I work in Korea on a medical visa or visa-free entry?
No. Neither tourist entry nor the C-3-3 medical visa allows employment in Korea. If you plan to work remotely during your medical stay, that’s a gray area. Technically Korea doesn’t regulate digital nomad activity for short-stay visitors, but it’s not formally authorized either.
What about my kids? Can they come?
Yes. Children can accompany you on their own passport (visa-free if eligible, or on a C-3-3 companion visa). Korean hospitals generally welcome family members, and Seoul is an excellent city for families: safe, clean, with plenty of kid-friendly activities.
I’m Russian. Is the visa process difficult?
It’s more paperwork than visa-free entry, but it’s a well-established process. The key document, the hospital confirmation letter, is something we handle for you. Russian citizens make up a significant portion of Korea’s medical tourists, and Korean embassies in Russia process medical visa applications routinely. Bucheon St. Mary’s Hospital, one of our partners, has Russian-licensed doctors on staff specifically to serve CIS patients.
What if my visa is denied?
Visa denials for medical tourism are uncommon when documentation is complete. The most common reasons for delay or denial are incomplete financial documentation or expired passport. If there’s an issue, we help you address it and reapply.
The Bottom Line
For most international patients, getting to Korea for medical treatment is easier than getting a specialist appointment in the US healthcare system. If you’re from a visa-free country, there’s zero additional paperwork beyond what you’d need for a vacation. If you need a visa, the process is straightforward and we handle the most important piece: the hospital documentation.
