Thailand Visa: Can Past TB Cases Get Work Visa?

"Yes — past TB (tuberculosis) patients can get a work visa in Thailand, as long as the disease is fully treated and no longer active. Thailand’s visa and work permit rules focus on current health risks, not past medical history.

Here is the professional explanation:

Can Former TB Patients Get a Thailand Work Visa?

Yes. If you previously had tuberculosis but have completed treatment and are now medically cleared, you are normally eligible for both:

A Non-Immigrant B work visa, and

A Thai work permit

Thailand does not automatically refuse visas to people with a past TB history.

When Could It Be a Problem?

There is only an issue if:

You currently have active TB, or

Your medical certificate shows that TB is still infectious or untreated.

For a work permit, Thailand requires a basic medical certificate from a Thai clinic or hospital, which checks for:

Leprosy

Tuberculosis (active cases only)

Drug addiction

Elephantiasis

Alcoholism (severe cases)

This test is to confirm you are not actively contagious.

What You Need as a Past TB Patient

If you had TB before, simply provide:

A medical certificate from a Thai doctor showing no active TB

(Optional but helpful) Previous treatment records or clearance letter from your doctor

The Thai authorities only care about present health status, not old records.

Important Notes

Old, healed TB scars on X-rays are not a problem.

If your chest X-ray shows old lesions, the doctor may ask for a sputum test or additional confirmation — but you can still pass the medical exam.

Only active, infectious TB cases can delay or stop work permit approval."
