How to Get a Work Permit in Thailand

Understanding how to get a work permit in Thailand is essential for any foreign national planning to work legally in the country. Thailand has a structured process that links employment, visa status, and company eligibility. This guide outlines the correct steps, timelines, and employer requirements.

How to Get a Work Permit in Thailand: Step-by-Step Process

1. Secure Employment or Establish a Legal Entity in Thailand

To begin the process of how to get a work permit in Thailand, you must have a confirmed position with a legally registered entity operating in Thailand. This entity may be Thai-owned or foreign-owned, provided it is authorized to employ foreign nationals.

2. Ministry of Labour Approval (Work Permit Support Letter)

The employing entity submits the required corporate and employment documentation to the Ministry of Labour to obtain a work permit support letter (approval in principle).
Processing time: approximately 7–10 business days.

This approval is required before applying for the appropriate visa.

3. Apply for a Non-Immigrant B (3-Month) Visa

Using the Ministry of Labour support letter, apply for a Non-Immigrant B visa (typically valid for 90 days) at a Thai embassy or consulate outside Thailand.
Processing time: approximately 3 weeks.

In-country visa conversion may be possible, depending on your current visa status.

4. Enter Thailand on the Non-Immigrant B Visa

Once the visa is approved, enter Thailand using the Non-Immigrant B visa.

5. Apply for the Work Permit in Thailand

After entering Thailand, submit the full work permit application at the Department of Employment, Ministry of Labour. Upon approval, the work permit is issued, allowing legal employment in Thailand.

6. Extend the Visa to One Year

Once the work permit is granted, apply at Thai Immigration for a one-year extension of stay based on employment.

When assessing how to get a work permit in Thailand, company eligibility is a critical factor. The employing entity must generally meet the following requirements:
