What You Need to Know About a Thailand Work Permit

A Thailand Work Permit is essential for a foreigner who is looking to live and work in the country. The process can be difficult and requires a great deal of documentation.

Every type of visa has different requirements and compliance is paramount for both employers and employees. There are also certain occupations that are restricted for foreigners.


Foreigners seeking employment in Thailand must meet several requirements, including possessing a valid non-immigrant visa and having a job offer from a legally registered Thai company. The company must comply with local labor laws and meet certain criteria, such as having a minimum amount of capital. In addition, the company must hire a certain ratio of Thai staff.

Foreigners also need to have a medical certificate that is signed by a doctor in Thailand. Additionally, there may be criminal background checks or other documents depending on the specifics of the job.

Both the employee and employer must prepare a variety of documents for the Ministry of Labour office, which include a copy of the passport and non-immigrant visa, a medical certificate, and a number of corporate documents such as the business registration, company affidavit, list of shareholders, etc. Typically, any documents originating from outside of Thailand must be legalized and translated into Thai before submission to the Ministry of Labour.

Employment Offer or Contract

In most cases, a foreigner is not allowed to work in Thailand without a valid Work Permit. To qualify for a permit, the foreigner must first secure a nonimmigrant visa that allows him to work and then file an application for a Work Permit at the Alien Occupational Control Division.

The employer must also submit a variety of company documents, such as a letter of invitation, certificate of incorporation, list of shareholders, financial statements and more. It is essential to have these documents ready in advance since even a minor oversight can cause significant delays.

Lastly, the company must provide proof that it has paid tax in the past three years and employs at least 50 Thai employees. Additionally, the work permit is tied to a particular occupation and employer, so any changes in these will require an updated work permit. The permit is not transferable between companies. If a foreigner leaves the company or is fired, they must take their work permit booklet to the Ministry of Labor to have it canceled.

Medical Certificate

A Thailand Work Permit is an essential document for anyone planning to work or conduct business in the country. While the process may seem daunting, there are certain things you can do to ensure a quick and seamless interaction with officials.

For instance, it is important to ensure that all documents are properly prepared. This applies to both the individual and the employer. This will help you avoid any unnecessary delays. It is also important to note that some occupations and industries are reserved for Thai citizens.

Moreover, the type of visa you hold will determine whether or not you are eligible for a Thailand work permit. For instance, the Non-Immigrant B Business Visa is suitable for foreigners who intend to invest or carry out business activities in the country. In addition, the SMART Visa is specifically designed for digital nomads and highly skilled professionals in high-demand fields.

Letter of Approval

The letter of approval for a Thailand Work Permit is one of the most important documents you and your employer will need to complete. It confirms that you are approved to work for your company and outlines what specific occupation you have been assigned. Without this document, you will not be able to work in Thailand. If your employment status changes in some way, such as if you switch to a different company or move to another location, then you will have to go through the process of revising your work permit.

Depending on your situation, you may need to submit a number of other documents in support of your work permit application. These can include copies of your passport and Non-Immigrant B visa, copies of educational certificates, a medical certificate, a copy of your marriage certificate, and various corporate documents from the employer including a business registration, company affidavit, list of shareholders, and financial statements.
