Overview

Any foreigner working in Thailand — whether employed, self-employed, or a company director — must hold a valid work permit. Operating without one carries serious penalties including fines, detention, and deportation. MJ & Co handles work permit applications and renewals at the Chiang Mai Labour Office.

We work with both employees and employers to ensure full compliance. This includes preparing all required documentation, coordinating with the company's registered accountant, and managing the timeline between visa and work permit applications (they're linked but processed by different government offices).

Whether you're starting a new job, renewing an existing permit, changing employers, or adding new job functions, our team ensures a smooth process with minimal disruption to your work.

Work Permit Requirements

  • Valid Non-Immigrant B visa (or qualifying visa type)
  • Employment contract or director appointment letter

  • Company registered capital of at least 2 million THB per work permit

Frequently Asked Questions

Do I need a work permit to freelance in Thailand?
If you're freelancing for Thai clients or performing work within Thailand, yes — you legally need a work permit. However, if you're working remotely for foreign clients on a DTV visa, you don't need a Thai work permit. The distinction is about who you're working for and where the work is directed.
How long does a work permit application take?
A new work permit application typically takes 7-14 business days after submission to the Labour Office. The total process including document preparation usually takes 3-4 weeks. Renewals are generally faster at 5-7 business days.
Can I change employers on my work permit?
You cannot simply transfer a work permit between employers. You need to cancel your existing permit and apply for a new one with the new employer. MJ & Co manages this transition to avoid gaps in your legal work authorization.
What happens if I work without a work permit?
Working without a valid work permit is illegal in Thailand. Penalties include fines up to 100,000 THB, imprisonment up to 5 years, and deportation with a potential re-entry ban. Employers who allow unauthorized work also face penalties.
