Work Permit

Work Permit is an official document that allows foreigners to legally work in Thailand, issued by the Department of Employment.
Under Thai law “work” refers to the use of physical force, knowledge, ability, or skills, whether or not wages or any other benefits are received.
Therefore, whether as:

  • Permanent employees
  • Executives
  • Consultants
  • Company directors
  • Specialized experts

If performing any work in Thailand, a work permit is required.

Why is a Work Permit important?

Even with a Non-B Visa, you ‘cannot work’ until you receive a Work Permit. Visa = Right of Stay; Work Permit = Right to Work. You must hold both concurrently.
