Medical Visa for Thailand

Thailand uses medical-treatment pathways within its visa system rather than one universal medical visa. The Thai embassy lists Tourist Visa (MT) for treatment-related travel and Non-Immigrant O for longer medical treatment stays; the correct route depends on nationality and duration.

Route

Tourist Visa (MT) / Non-Immigrant O (Medical Treatment)

Typical processing

At least 15 working days before intended travel

Validity

Usually 90 days for a single-entry visa; confirm the issued visa

Permitted stay

Up to 90 days per entry for the listed medical-treatment routes

The short answer

A medical-treatment route is listed for this country

The route below is the official starting point, but your passport, treatment length, and filing location can change the result.

Who this route is for

People seeking medical treatment, rehabilitation, or related medical services in Thailand.
Applicants whose treatment provider can issue the appointment, confirmation, or hospital letter requested by the Thai mission.
Applicants staying beyond the short-term route who meet the Non-Immigrant O medical-treatment requirements.

Documents to prepare

Passport valid for at least six months with at least one blank visa page.
Completed online e-Visa application and recent photograph.
Proof of current location or residence where the application is filed.
Hospital or medical-facility appointment/confirmation letter showing the treatment plan or dates.
Financial evidence meeting the mission's stated threshold for the selected category.
Additional documents requested by the embassy or consulate for your nationality.

Application steps

1
Choose MT or Non-Immigrant O
Use the Thai mission's current category guidance to match the planned stay and treatment length.
2
Get the provider letter
Ask the Thai hospital or clinic for the appointment or treatment confirmation required by the mission.
3
Apply through Thai e-Visa
Create an account, upload the category-specific documents, pay the fee, and monitor the application.
4
Check entry and extension rules
The visa validity and permitted stay are separate. If more time is needed, ask Thai Immigration before the current permission expires.

Check before you submit

Common rejection risks

Selecting a category that does not match the length or purpose of the treatment visit.
Hospital confirmation, dates, or financial evidence is missing or inconsistent.
Passport, residence, or photograph requirements are not met.
Submitting too close to departure for the mission's stated processing window.

Frequently asked questions

Is Thailand's medical visa called MT?

MT is one medical-treatment route listed by Thai missions. Longer stays may use Non-Immigrant O medical treatment, so confirm the category with the responsible mission.

Can a medical-treatment stay be extended?

Some permissions may be extended by Thai Immigration at its discretion. Ask before the current permission expires; do not assume an extension is automatic.

What is the safest first document to request?

Ask the hospital or clinic for the exact appointment or treatment confirmation letter required by the Thai mission handling your application.
