In Thailand, the Alien Working Act B.E. 2551 reserves 39 professions exclusively for Thai nationals. Some of the most well-known include: tour guide, lawyer, accountant, farmer, street vendor, tailor, and manual construction worker. Any violation can result in fines and deportation.
Why Does Thailand Prohibit Certain Jobs for Foreigners?
Thailand protects its domestic labor market through a list of professions strictly reserved for Thai citizens. These restrictions are established by the Alien Working Act B.E. 2551 (2008) and its implementing decrees. The dual aim is to safeguard local employment in sensitive sectors and to protect certain artisanal or professional skills deemed cultural heritage.
⚠️ Warning
Working in a prohibited profession in Thailand — even unknowingly — is a criminal offense. Penalties include fines of up to 100,000 baht, imprisonment for up to 5 years, and cancellation of your work permit with a ban on re-entry.

How to Check if Your Profession is Allowed?
Before starting work in Thailand, three steps are essential:
- Consult the official list published by the Thai Department of Employment (DOE)
- Obtain a valid work permit for your specific position
- Have your contract reviewed by a lawyer specialized in Thai labor law
✅ Practical Advice
Even if your profession is not formally prohibited, it must be explicitly stated on your work permit. Changing positions or assignments without updating this document is illegal. If in doubt, consult your employer, your embassy, or a local professional.
In Case of Violation: What Are the Consequences?
Thai authorities conduct regular inspections, including in foreign-owned businesses. A foreigner working in a prohibited profession risks:
- A fine of up to 100,000 THB
- A prison sentence of 1 to 5 years
- The immediate cancellation of the work permit and visa
