Working or starting a business on Koh Samui means first getting the paperwork right. You'll need a Non-Immigrant B Visa, which is your ticket to work legally in the country, before you arrive in Thailand. Once you're on the island, the next step is to get a work permit from the Thai Ministry of Labour. This permit is proof that you're allowed to work in Thailand. The process involves filling out some forms and showing that you have a job or business plan. In simple terms, these two steps – getting your Non-B visa and then your work permit – are what you need to do to work in Koh Samui legally. Let's break down how to smoothly navigate through this process, so you can focus on enjoying the island life while working.

What is a Non-B Visa?

Whether you're looking to start a business or accept a job legally working in Thailand, this will be your first step. The Non-B Visa is a type of Thai visa specifically designed for foreigners who wish to work or engage in business within Thailand. Unlike tourist visas, the Non-B Visa permits holders to undertake employment or business activities and is a prerequisite for obtaining a work permit. This visa serves as the gateway for professionals, educators, and entrepreneurs looking to contribute to Thailand's vibrant economy.

Obtaining a Non-B Visa is the initial step for expatriates to embark on their professional journey in Thailand. It highlights the Thai government's requirements for foreign workers, ensuring that only qualified individuals engage in employment or business ventures within its borders. The visa not only legalizes your employment status but also facilitates the process of adapting to Thailand's business environment, setting a solid foundation for your career or business in the country.

If you're already in Thailand on another type of visa, you'll need to leave the country and submit the paperwork from there. We'll outline a few of the common places to go below.

Where to Apply for a Non-B Visa


The Royal Thai Embassy in Vientiane serves as a central hub for visa applications, situated in the heart of Laos' capital. This key location is not only pivotal for those looking to secure a Non-Immigrant Visa B (Non-B Visa) for work or business in Thailand but also for a variety of other visa needs. Staffed with experienced personnel, the embassy provides comprehensive guidance on the application process, required documentation, and other procedural nuances. Its strategic placement in Vientiane makes it accessible for residents and visitors in the capital, streamlining the process for those seeking to navigate the complexities of Thai visa requirements. You can also apply at Consulate-Generals in Savannakhet and Luang Prabang.

The most common route to Vientiane from Koh Samui includes first taking a ferry to the mainland, with Surat Thani being a popular disembarkation point. From Surat Thani, travelers can opt for a bus or a train to reach Udon Thani or Nong Khai in Thailand, both of which are near the Laos border. Udon Thani is particularly well-connected by bus services that go directly to Vientiane. Alternatively, for a faster journey, direct flights from Koh Samui to Bangkok followed by a connecting flight to Vientiane offer a quicker, albeit more expensive, option. Once at the border, a short bus ride or a taxi will take you across the Friendship Bridge into Vientiane. Each mode of transport provides a unique blend of convenience, cost, and travel time, allowing travelers to choose based on their preferences, schedule, and budget.


The Royal Thai Embassy in Kuala Lumpur, centrally located in Malaysia's dynamic capital, alongside the Royal Thai Consulate-General in George Town, Penang, form the keystones of Thailand's visa application services in Malaysia. The embassy in Kuala Lumpur caters to the diverse needs of applicants from across the country, offering guidance and assistance for a smooth visa application process, including the Non-Immigrant Visa B. Meanwhile, the consulate in Penang, situated in the heart of its historic capital, provides convenient access for residents of the northern region, eliminating the need for a lengthy journey to Kuala Lumpur. Both diplomatic missions are equipped to facilitate the visa application process, showcasing Thailand's dedication to promoting ease of travel and fostering cultural exchanges with its Malaysian neighbors.

Traveling from Koh Samui to Penang involves a combination of ferry, bus, or flight options to suit various preferences and schedules. The journey typically starts with a ferry ride from Koh Samui to the mainland, such as Surat Thani, followed by a bus or minivan transfer across the Malaysian border into Penang. This route offers scenic views and a glimpse into the local way of life. Alternatively, for a quicker trip, travelers can opt for a direct flight from Koh Samui to Penang, although this option might require a connection in Kuala Lumpur depending on airline schedules.

Getting to Kuala Lumpur from Koh Samui is streamlined with direct flights available, offering the fastest and most convenient route between these two popular destinations. The flight takes approximately 1.5 hours, bringing travelers directly into Kuala Lumpur International Airport, which is well-connected to the city center and beyond. For those seeking a more adventurous route, taking a ferry to the mainland followed by a bus or train journey southwards through Thailand to the Malaysian border, and onwards to Kuala Lumpur, presents an opportunity to see more of the countryside, though it significantly increases travel time.


In Cambodia, the Royal Thai Embassy located in Phnom Penh and the Thai Consulate-General in Siem Reap are the principal points for handling Thai visa applications, catering to a broad spectrum of needs from tourism to business ventures. The embassy in Phnom Penh, situated in the bustling capital, serves as a comprehensive resource for applicants from across Cambodia, providing detailed guidance on the visa process. Meanwhile, the consulate in Siem Reap, strategically placed to serve the northwest region of the country, offers a convenient option for those residing in or near this culturally rich area, known for the Angkor Wat temple complex. Together, these diplomatic missions facilitate the visa application process for Cambodians and international residents alike, ensuring accessibility and support for travel or work in Thailand.

To reach Phnom Penh or Siem Reap from Koh Samui, travelers typically fly to Bangkok, with onward connections to either city via direct flights, offering a quick and efficient way to transition from the tranquility of Koh Samui to the rich cultural tapestry of Cambodia. For those inclined towards an overland adventure, the journey involves a ferry ride from Koh Samui to Surat Thani, followed by land transportation to Bangkok, and then continuing to Phnom Penh or Siem Reap by bus or flight. This route allows for a scenic exploration of the countryside, presenting a blend of convenience and adventure tailored to diverse travel preferences.

Required Documentation

Working for a Thai Company

To apply to work for a Thai company, you will need to prepare and submit several key documents. The specific requirements may vary slightly depending on the Thai embassy or consulate where you apply, but generally, you will need the following:

  • Passport: Your passport must be valid for at least 6 months beyond the date of your application and have at least two blank pages for the visa.
  • Visa Application Form: A completed and signed visa application form, available from the Thai embassy or consulate's website or office.
  • Recent Passport-Sized Photographs: Typically, two color photographs taken within the last six months, adhering to the visa photo specifications.
  • Job Offer Letter: A letter from the Thai company offering you employment, detailing the position, salary, and duration of your contract.
  • Company Registration Documents: Copies of the company's registration, commercial registration, and list of shareholders. This shows that the company is legally registered in Thailand.
  • Company License: A copy of the company's business license, issued by the relevant Thai government body.
  • Financial Statements: Recent financial statements from the company to prove its financial viability and capability to hire foreign workers.
  • Company Profile: A brief profile of the company, including its business activities, contact information, and sometimes, the reason for hiring foreign nationals.
  • Work Experience and Education Certificates: Documents proving your qualifications for the job, such as diplomas, certificates, and letters of reference from previous employers.
  • Proof of Address in Thailand: Sometimes, proof of a residential address in Thailand is required, such as a rental agreement.
  • Visa Fee: The application fee, which varies depending on the country where you apply and the duration of the visa.

It's important to check with the specific Thai embassy or consulate for any additional requirements or changes to the application process. Preparing these documents meticulously is crucial for a smooth application process and to increase your chances of approval.

Starting a Business

If you're opening your own company in Thailand and applying for a Non-Immigrant B Visa (Non-B Visa) based on this business venture, the documentation you'll need to provide can be more extensive than for employment under a Thai company. This is because you must prove not only your personal qualifications but also the legitimacy and viability of your business. Here’s a list of additional or altered documentation you may need:

  • Business Plan: A detailed plan for your business, including the nature of the business, financial projections, and how it will benefit Thailand’s economy.
  • Company Registration Documents: Proof of company registration with the Thai Ministry of Commerce, including your company name reservation, memorandum of association, and articles of incorporation.
  • Commercial Registration Certificate: A certificate showing your business is properly registered for commercial activities in Thailand.
  • Shareholder Information: Documentation detailing the share distribution among shareholders, ensuring compliance with Thai law, which typically requires a majority of shares to be held by Thai nationals.
  • Capitalization Evidence: Proof of adequate capitalization for your business venture, as required by Thai law. This could include bank statements or evidence of investment into the company.
  • Office Lease Agreement: A lease agreement or proof of ownership of an office space in Thailand, demonstrating you have a physical location for your business.
  • Financial Projections: Detailed financial forecasts for your company, showing its potential for growth and sustainability.
  • Board of Investment (BOI) Certificate: If applicable, a BOI certificate can greatly facilitate the process of obtaining a Non-B Visa and work permit, as it shows government endorsement of your business.

Opening a company in Thailand and applying for a visa based on this requires careful planning and adherence to Thai laws, particularly regarding foreign ownership and investment. It's highly recommended to consult with legal and financial experts in Thailand to ensure all aspects of your business and visa application are correctly handled. This approach not only increases your chances of a successful visa application but also sets a solid foundation for your business in Thailand.

Getting a Work Permit on Koh Samui

Upon obtaining a Non-B visa, securing a work permit on Koh Samui involves visiting the Office of Employment in Nathon, the island's main administrative center. Applicants need to present their Non-B Visa, passport, job offer letter, employer’s business documents, and personal qualifications. The process, typically facilitated by the employer, requires showing that the position cannot be filled locally. A successful application grants a work permit valid for up to one year, renewable with ongoing employment and valid visa status. It's crucial to initiate this process shortly after arrival to ensure you meet Thai employment regulations. For a full guide to this process check out our Koh Samui Work Permit Guide.

If you're opening a company on Koh Samui, the process is a bit more complex, but starts with company registration with the Thai Ministry of Commerce, ensuring compliance with the Foreign Business Act, and meeting the minimum capital requirements. Subsequent steps include obtaining a Tax Identification Number and registering for VAT if applicable, securing social security for employees, and applying for a work permit to legally work within your business. Depending on your business type, additional specific licenses or permits may be required. Opening a corporate bank account is essential for financial transactions, and adherence to Thai labor laws is mandatory when hiring staff. Regular financial reporting and staying compliant with all relevant Thai laws are critical for operational legality and success. Given the complexity of these processes, especially for foreigners, consulting with legal and financial experts in Thai business law is highly recommended to navigate the intricacies of establishing and running a business in Thailand smoothly.

Working Legally from Koh Samui

Starting a job or business on Koh Samui begins with obtaining a Non-Immigrant B Visa, your essential pass to work legally in Thailand. This process involves gathering specific documents, including a job offer or business registration details, and possibly leaving Thailand to apply from a neighboring country like Laos, Cambodia, or Malaysia. Once on Koh Samui, securing a work permit from the Office of Employment in Nathon is crucial, marking your legal authorization to work. For entrepreneurs, additional steps like drafting a business plan, ensuring proper capitalization, and navigating Thai business laws are vital. Each step, from visa application to work permit acquisition, is pivotal in transitioning smoothly to a professional life in Koh Samui.
