Thailand Work Permit: A Practical Overview

Introduction to Work Permits in Thailand

Foreigners working in Thailand need a work permit, as required by the Royal Emergency Decree on Managing the Work of Foreigners B.E. 2560 (2017), as amended by the Royal Decree (No. 2) B.E. 2561 (2018) (the “Emergency Decree”).

The Emergency Decree defines ‘Working’ as “engagement in any occupation, with or without an employer,” except for business operations conducted by those licensed under the foreign business law.

Restricted Jobs for Foreigners in Thailand

Some jobs in Thailand are reserved only for Thai nationals. Foreigners should ensure their intended job isn’t restricted. For details on restricted jobs and exceptions, please refer to our full guide on restricted jobs for foreigners in Thailand.

Penalties for Non-Compliance with Work Permit Rules in Thailand

For Foreign Workers:
Foreigners working without a valid permit can be fined 5,000 to 50,000 baht. Additional penalties may include deportation and a two-year ban on obtaining a new work permit from the date of the offense​

For Employers:
Employers who hire foreign workers without the required permits are subject to fines ranging from 10,000 to 100,000 baht per illegal worker. In cases of repeat offenses, the penalties increase to fines of 50,000 to 200,000 baht per worker, with the possibility of imprisonment for up to one year. Repeat offenders also face a three-year ban from hiring foreign workers​.

How to Obtain a Work Permit in Thailand

Foreigners need a work permit to legally work in Thailand, whether they are employed by a Thai employer or starting their own company, and need a work permit to work as a director or in another role. Obtaining a work permit can be particularly tricky when starting new businesses and for foreigners setting up their own companies, as there is no support from existing Thai employers.

Work Visa in Thailand

Typically, a work permit is issued to those holding a Non-Immigrant B Visa (Non-B), commonly referred to as a “business visa” or “work visa.” The term “work visa” is conditional in Thailand, implying a Non-B visa in conjunction with a work permit. Besides work, the Non-B visa is also intended for business and other cases. Furthermore, holders of investment visas, LTR visas, as well as those married to Thai nationals or having Thai children with non-immigrant type “O” visas, can also obtain work permits. Work permits can also be acquired by those with Thai permanent residence. However, in this article, we will focus on the most typical case: the Non-Immigrant B Visa.

Usually, a foreigner obtains a Non-Immigrant visa at one of the Thai embassies or consulates based on documents provided by the future Thai employer (which could be your company if you are starting a business). A key document for processing the work visa is the approval letter that the Thai employer must obtain from the Department of Employment, form WP.3. Companies with projects approved by the Board of Investment (BOI) process BOI letters instead of WP.3. When applying for a visa, it is important to consider the requirements of the specific embassy or consulate. The validity of such a Non-B visa is 90 days.

After entering Thailand, a work permit is processed based on documents from both the employer and the employee, typically for one year (although it might be less for newly founded companies). With a Non-B visa and a work permit, you can obtain an extension of stay at the local Immigration office, usually issued for one year.

Basic Requirements for the Employer

Registered Capital

To employ one foreigner, two million baht of registered capital is required. This amount is one million baht if the foreigner is married to a Thai national. For foreign companies, this amount is three million baht.

Thai Employees

For each foreign employee, there should be no fewer than four Thai employees (no fewer than two if the foreigner has a Thai spouse). This rule does not apply to holders of LTR visas. For representative offices of foreign companies and regional offices, the rule is “one work permit – one Thai employee.”

Number of Foreign Employees

Typically, an employer company can hire no more than ten foreigners. There are some exceptions based on economic indicators, taxes paid, the number of Thai employees, certain types of activities, etc.

BOI Projects

Special rules apply to companies whose projects have received BOI benefits.

Three Key Steps to Obtaining a Thai Work Permit

  1. Obtaining the Pre-Approval Letter (WP.3 Form)
    The WP.3 form is a pre-approval document issued by the Department of Employment. This step is essential to verify that the job position qualifies for a foreign worker and meets legal requirements.
  2. Securing the Non-Immigrant B Visa
    Once the WP.3 is approved, apply for a Non-Immigrant B visa at a Thai consulate or embassy abroad. This visa allows entry to Thailand for employment purposes and is required before applying for the work permit.
  3. Processing the Work Permit
    After arriving in Thailand, the work permit application is submitted. This involves providing all necessary documentation from both the employer and the employee, including the WP.3 form and visa-related paperwork.

Employers are responsible for managing the visa and work permit process. If you are setting up your own company, hiring a lawyer, law firm, or other professionals is highly recommended. This ensures that all legal procedures are correctly followed, avoiding delays or compliance issues.

Getting Pre-Approval (WP.3 Form)

What is the WP.3 Form?

The WP.3 form verifies that your company is authorized to employ foreign workers and is a prerequisite for applying for the 90-day business visa at a Thai embassy abroad. This form acts as confirmation from your employer in Thailand, verifying your intention to work for their company. If you are already living in Thailand, you will need to leave the country to submit the application, as it can only be submitted if the foreigner is not in Thailand.

Required Documents for WP.3 Application

Personal Documents:

  • Completed WP.3 form
  • Employment certification form
  • Copy of the first page of the passport of the foreign candidate
  • Copy of the education certificate or determination form (if you don’t have an educational certificate)
  • Copy of the occupation or professional license (if applicable)
  • Power of Attorney from the employer
  • Copy of the employer’s identification card and a copy of the grantee’s I.D. card

Company Documents:

  • Copy of Thai company registration and recent shareholders’ list (updated within 6 months). For foreign juristic persons, a copy of the Business Operation of foreigners and documents about money import
  • Copy of VAT registration
  • Copy of the employer’s work permit (if applicable)
  • Relevant company licenses (e.g., factory, restaurant, hotel, tourism, hospital, etc.)
  • Copy of social security payment (1 month), balance sheet (last year), and VAT payment records (1-3 months)

Need for a Thai Director

If you plan to obtain a work permit in a newly established company, whether for a director’s position or any other role, the application must be signed by a Thai director. Therefore, it’s important to appoint a Thai director first. This individual will be required throughout the entire process, including obtaining the WP.3 form, visa, and work permit, and must remain in this position at least until all formalities are completed.

Submitting the Application

The employer submits the WP.3 form and required documents to the Department of Employment.

Awaiting Approval

The Department of Employment reviews the application, which can take several days.

Receiving the Pre-Approval Letter

Once approved, the employer receives the WP.3 letter, necessary for applying for the Non-Immigrant B Visa. Most consulates accept scanned copies, so the employer or a representative can email a pre-approval letter to the employee.

When WP.3 is Not Needed

In some cases, the WP.3 form is not required. Here are the exceptions:

  • Companies Approved by the Board of Investment (BOI): Companies that have received approval from the BOI can use a letter from the BOI instead of the WP.3 form.
  • Japanese Nationals: Japanese nationals are exempt from submitting the WP.3 form per the Japan-Thailand Economic Partnership Agreement (JTEPA).
  • Other Documents: Other documents can replace the WP.3 approval letter, such as letters from universities, schools, international organizations, or charitable organizations.

Obtaining the Non-Immigrant B Visa

After receiving the WP.3 form, you can proceed to apply for the Non-Immigrant B Visa at a Thai consulate abroad. It’s crucial to choose the consulate in advance since the company documents must be addressed to a specific consulate, and requirements can vary. Many consulates also require an appointment, so be sure to plan ahead.

Collecting Your Work Permit

After the review period, the foreign applicant must personally visit the Labour Department office to collect the work permit booklet.

Work Permit Validity and Renewal

The work permit is generally valid for one year but may sometimes be issued for shorter periods such as six or three months. The duration can depend on various factors including the applicant’s nationality, the newness of the company, and the validity of the applicant’s passport. It is essential to renew the work permit as required to ensure the foreigner can legally work in Thailand.

Extension of Stay

Based on a Non-B visa and work permit, one can obtain an Extension of Stay at the territorial division of the Immigration Service. It is represented by a stamp in the passport with the date until which the person has the right to legally stay in the country. It is typically issued for 1 year. The criteria for extension are established by Order No. 327/2557 of the Immigration Bureau of the Royal Thai Police dated June 30, 2014. A translation of the order is available, for example, on the website of the Thai Embassy in Prague. However, we recommend monitoring current changes in requirements. In practice, it is strongly advised to verify the requirements of the specific immigration office before extending, to ensure a smooth visa extension process.

Minimum Wage for Foreign Workers

For foreign workers in Thailand, minimum wages depend on nationality. Below is a table of minimum wages based on the region of origin, according to Annex A to Order No. 327/2557 of the Royal Thai Police Bureau, dated June 30, 2014.
