Who Needs a Work Permit & What Are the Steps?

As businesses in Thailand grow—despite ongoing challenges—more foreigners are looking to experience working life in the Land of Smiles. Meanwhile, local employers are expanding their diverse workforce with open arms.


However, extensive documentation and administrative processes remain a major obstacle. Without a strong understanding of the procedures, employers may end up with unsuccessful hires, wasting both money and time. 

To help you navigate this complicated process and stay in sync with hiring foreign professionals, we've researched and outlined the key steps you need to follow. 

Who Needs a Work Permit?

A work permit is a legal document that allows foreign professionals to work in Thailand. It outlines the occupation, position, and hiring company. Without a valid permit, both workers and employers could face legal consequences. 

Individuals who require a work permit include: 

  • All non-Thai citizens who plan to work in Thailand 
  • Foreign professionals employed by Thai companies 
  • Individuals conducting business in Thailand 
  • Freelancers and consultants working on projects in Thailand 

 

Steps Toward Obtaining a Work Permit

1. Secure a Non-Immigrant B Visa

Employers must first ensure that their foreign professionals obtain a Non-Immigrant B visa from their home country—a prerequisite for applying for a Thai work permit. 

Here are the qualifications for Non-Immigrant B Visa:  

  • Individuals must possess the required knowledge and skills for particular work. 
  • Individuals must not be mentally disturbed   
  • Individuals must not have been convicted of any offense under immigration law or foreign labor law within one year prior to the date of application for the work permit. [1] 

Challenges 

  • Extensive documentation: Valid passport, job offer letter, financial proof, application forms 
  • Approval delays: Processing can take several weeks 

Solutions 

  • Prepare thoroughly: Ensure documents are complete and accurate 
  • Apply early: Start the process well in advance 

 
2. Prepare Required Documents

Once the visa is secured, employers must gather essential documents for the work permit application, including the employment contract, company registration, and the employee’s qualifications. 

Challenges 

  • Complex requirements that vary by role and industry 
  • Risk of non-compliance with Thai legal standards 

Solutions 

  • Use a detailed checklist to ensure nothing is missed 
  • Professional assistance is highly recommended. You may consider consulting experts like those under Adecco’s Visa & Work Permit Administration service 


3. Submit the Application

The employer must submit the application to the Ministry of Labor or relevant provincial office, along with all necessary forms and documents. 

Challenges 

  • Navigating bureaucratic procedures 
  • Language barriers 

Solutions 

  • Engage a local agency that is familiar with the system 
  • Use professional translation services for documentation 

4. Wait for Processing

The review process generally takes 7–10 business days in Bangkok, but may take longer in other provinces. [2] 

Challenges 

  • Uncertain timelines 
  • Requests for additional documents 

Solutions 

  • Follow up regularly with the labor office 
  • Respond promptly to any additional requirements 

5. Receive the Work Permit

Upon approval, the foreign professional receives their work permit and can legally begin employment in Thailand. 

Challenges 

  • Ensuring permit details are accurate 
  • Renewing permits and staying compliant with Thai labor laws 

Solutions 

  • Review the permit carefully 
  • Track renewal timelines and legal updates
