[Medical Tourism Visa] Inviting Foreign Patients to Korea: From C-3-3 Visa Issuance to G-1-10 Status Change

Service 2: Visa, Immigration & Nationality

Hello! This is Administrative Attorney ON (Onhaeng), your dedicated partner in navigating immigration legalities, medical tourism visas, and foreign patient invitation procedures in South Korea.

When plastic surgery, dermatology, or specialized clinics in Gangnam and across Seoul consult foreign patients, one of the most frequent administrative bottlenecks is the visa issue. Scheduling appointments is straightforward, but what happens when a patient requires extended recovery observation or revision surgery?

Many clinics ask: "Our medical center is not yet designated as an 'Excellent Attracting Institution' (우수 유치기관). Can we still invite foreign patients directly?" The answer is a clear YES. As long as your hospital or clinic is registered with the Ministry of Health and Welfare (MOHW) as an official Foreign Patient Attracting Medical Institution, you can safely invite international patients via the official Confirmation of Visa Issuance (사증발급인정서) system.

Procedure for Inviting Foreign Patients via Visa Issuance Confirmation

The most reliable method for standard registered healthcare providers to sponsor foreign patients is submitting an application for a Confirmation of Visa Issuance through the Ministry of Justice Korea Visa Portal.

The 4-Step Medical Visa Issuance Flow

  1. Online Application: Registered hospital or administrative proxy files the application online via the Korea Visa Portal.
  2. Immigration Review: The competent Korean immigration office reviews medical necessity and financial credibility.
  3. Confirmation Number Issuance: Upon approval, a Visa Issuance Confirmation Number is generated.
  4. Visa Collection: The patient submits the confirmation number to their local Korean Embassy/Consulate to receive the C-3-3 medical visa quickly.

*Applying through this domestic sponsorship pipeline yields a significantly higher approval rate and far easier management compared to having the patient apply directly at overseas consulates. Please note that official registration as an Attracting Medical Institution is a prerequisite before sponsoring patients.*

Required Documents for Patient Invitation (C-3-3 Visa)

Medical institutions without "Excellent" status must thoroughly substantiate the legitimacy and financial viability of the visit:

  • Application for Confirmation of Visa Issuance and passport copy
  • Standardized passport-sized color photograph
  • Documentary evidence of medical purpose (diagnosis letter, treatment schedule, appointment confirmation from the Korean physician)
  • Proof of financial capability to cover medical treatments and living expenses in Korea (bank balance certificates, income statements)
  • Copy of Business Registration Certificate and Foreign Patient Attracting Institution Certificate
  • Supplementary relationship documents if accompanied by immediate family members or caregivers

*(Note: Once designated as an "Excellent Attracting Institution," several financial documents are exempted, and clinics can issue direct electronic visas with simplified processing).*

When Long-Term Treatment Is Required: Status Change to G-1-10

Post-surgical recovery may encounter complications, extended observation periods, or revision procedures that exceed the standard 90-day short-term stay (C-3-3).

💡 In-Country Change of Status to G-1-10 (Medical Treatment & Recuperation)

In cases where treatment exceeds 90 days, the patient must apply for an in-country Change of Status to G-1-10 (치료요양) at the jurisdictional Korean immigration office prior to visa expiration.

  • Medical Opinion & Future Treatment Plan: Detailed specialist documentation explaining why the patient cannot travel and the exact timeline required for recovery is decisive.
  • Mandatory Alien Registration: If consecutive stay exceeds 90 days, the patient must formally complete Foreigner Registration and receive an Alien Registration Card (ARC) within that 90-day window.

The Strategic Role of a Registered Administrative Attorney

Managing foreign patient visas internally places undue operational strain on hospital coordination desks and exposes clinics to compliance risks:

  • Pre-Screening Dossiers: Rigorous evaluation of patient financial proof to secure high visa issuance approval rates.
  • Visa Portal Representation: Authorized direct electronic filing with the Ministry of Justice on behalf of the medical facility.
  • Post-Entry Risk Management: Monitoring departure compliance, filing timely stay extensions, and shielding the clinic from administrative penalties linked to illegal overstays.

Conclusion

Starting as a standard registered attracting institution is the initial step toward building a verified performance record. Our office not only manages immediate visa sponsorships, but also designs strategic compliance roadmaps to help your hospital eventually qualify as an Excellent Attracting Institution eligible for direct electronic visa privileges.
