Visa requirements are a practical constraint that many patients leave until late in the planning process. Getting this wrong can mean arriving on a visa category that does not permit the length of stay your recovery requires, or being unable to remain if complications extend your stay. This guide covers the basic visa situation for each of the ten countries covered by The Treatment Registry. Immigration rules change; verify current requirements through official government sources before booking.
Thailand
Thailand offers a specific Medical Treatment Visa (Non-Immigrant O-A) for foreign nationals entering for medical purposes. This is valid for 90 days initially and can be extended. Required documentation typically includes a letter from a recognised Thai hospital confirming the planned treatment, proof of funds, travel insurance meeting the minimum coverage requirement, and a passport valid for at least 18 months.
For shorter stays, many nationalities can enter Thailand visa-exempt for up to 30 days (or up to 60 days for some nationalities under an extended exemption programme), which is sufficient for minor procedures but may not accommodate major surgery with extended recovery. Visa-exempt stays can sometimes be extended at an immigration office once in-country, but this is not guaranteed. Plan conservatively.
Turkey
Most nationalities can enter Turkey visa-free or with an e-Visa for stays of up to 90 days within a 180-day period. This is sufficient for the vast majority of medical tourism cases. Turkey does not have a specific medical visa category; the standard tourist e-Visa or visa-free entry is used. Check the current list of eligible nationalities at the Turkish Ministry of Foreign Affairs website, as eligibility and conditions change.
For longer stays required by extended recovery, a residence permit (ikamet) can be applied for in-country. This is a more complex process and not typically necessary for medical tourism.
Mexico
Mexico does not require a visa for nationals of most Western countries; entry is on a Forma Migratoria Multiple (FMM) tourist permit valid for up to 180 days. The FMM is issued on arrival or in advance online. This is generally sufficient for medical tourism purposes.
For extended stays beyond the FMM period, or for patients from nationalities that do require a visa for Mexico, the relevant visa category is the Visitante (visitor) visa. Mexico does not have a dedicated medical visa category. Confirm your nationality's requirements at the nearest Mexican consulate.
Hungary
Hungary is a Schengen Area member state. Citizens of Schengen Area member states may stay indefinitely. Citizens of most other developed nations may stay visa-free for up to 90 days within any 180-day period under the Schengen visa-free regime. This is sufficient for most medical tourism stays.
Patients from countries requiring a Schengen visa should apply for a short-stay Schengen (C) visa with a medical purpose noted in the application, providing the clinic's confirmation letter as supporting documentation. Hungary offers extended-stay options for patients requiring longer treatment, coordinated through the Hungarian immigration authority.
India
India operates a specific Medical Visa (M-Visa) designed for foreign nationals travelling for medical treatment. The M-Visa is valid for the treatment period, initially granted for 60 days with the possibility of extension up to one year. It allows multiple entries. Required documentation includes an invitation or letter from a recognised Indian hospital, details of the planned treatment, and proof of sufficient funds.
A Medical Attendant Visa (MX-Visa) is available for companions travelling with the patient. Up to two attendants can receive MX-Visas per patient. Applications are made through the Indian e-Visa system or at the nearest Indian High Commission or Consulate. Processing times vary by nationality; apply well in advance.
South Korea
South Korea offers a Medical Tourism Visa (Medical C-3-3) for short stays of up to 90 days, and a Medical Stay Visa (G-1-10) for longer treatment periods. The C-3-3 is suitable for most medical tourism procedures. Required documents include a medical certificate or treatment plan from a Korean healthcare institution.
Many nationalities can enter South Korea visa-free for short stays, but the specific medical visa categories offer longer permitted stays and clearer documentation of purpose if questions arise. Check current requirements at the Korea Immigration Service website.
Malaysia
Malaysia does not have a specific medical visa category for most visitors. Nationals of most countries can enter visa-free for 30–90 days depending on nationality, which is typically sufficient for medical tourism. The Malaysia Healthcare Travel Council (MHTC) facilitates longer-stay arrangements for patients requiring extended treatment.
For longer stays, a Long-Term Social Visit Pass can be applied for through the Immigration Department of Malaysia on medical grounds, supported by documentation from a recognised Malaysian healthcare provider.
Costa Rica
Costa Rica does not require a visa for nationals of most developed countries; entry is on a standard tourist stamp valid for 90 days, which is generally sufficient for medical tourism stays. Costa Rica does not have a dedicated medical visa category.
For extended recovery periods beyond 90 days, extension requests can be filed with Costa Rican immigration, though this process has variable outcomes. For most medical tourism purposes, the 90-day tourist entry is adequate.
Spain
Spain is a Schengen Area member state; the same rules described under Hungary apply. EU and EEA citizens have unrestricted entry and stay. Citizens of non-EU countries with Schengen visa-free access may stay up to 90 days in any 180-day period without a visa. Those requiring a Schengen visa should apply for a short-stay medical visa with supporting documentation from the treating clinic.
Poland
Poland is also a Schengen Area member state, and the same Schengen rules apply. EU and EEA citizens have free movement rights. Non-EU citizens with Schengen visa-free access may stay up to 90 days in any 180-day period. Those requiring a visa should apply for a Schengen C-visa noting medical purpose.
General Advice on Medical Stays and Overstays
Calculate your stay conservatively. If your planned surgery requires a two-week minimum recovery before flying, and your procedure is scheduled four days after arrival, you need a visa that permits at least 18 days — but plan for 25 in case recovery is slower than expected or follow-up reveals a need to stay longer.
Do not assume that a complication will automatically justify an overstay. Some countries are lenient in genuine medical emergencies; others impose fines for overstays regardless of circumstance. The safest approach is to enter on a visa category that accommodates the longest plausible stay you might need, not the shortest.
Your medical documentation — clinic letters, treatment plans, discharge summaries — is important if immigration officials question the purpose of your visit, particularly if you are staying for an extended period.
