Thailand Business Visa (Non-Immigrant B Visa) – A Comprehensive Guide

If you’re planning to work, start a business, or engage in professional activities in Thailand, the Non-Immigrant B Visa is the standard visa required. This visa is essential for foreign employees, entrepreneurs, and business professionals looking to legally work and operate in Thailand.

In this guide, we’ll cover the different types of Thailand Business Visas, eligibility requirements, the application process, and key considerations to help you navigate your way through Thai immigration laws.


There are two main types of Non-Immigrant B Visas, each suited to different needs and lengths of stay.

1. 90-Day Non-Immigrant B Visa (Single-Entry)

  • This visa is initially valid for 90 days from the date of entry.

  • It is a single-entry visa, meaning that if you leave Thailand, the visa will be void unless you obtain a re-entry permit beforehand.

  • It is typically issued for individuals seeking employment or setting up a business in Thailand before applying for a long-term extension.

2. 1-Year Non-Immigrant B Visa (Multiple-Entry)

  • This visa is valid for 1 year, allowing the holder to enter and exit Thailand multiple times.

  • Unlike the 90-day visa, you don’t need a re-entry permit when traveling in and out of Thailand.

  • However, you must exit and re-enter the country every 90 days to maintain valid status unless extended to a full one-year stay inside Thailand.

  • It is commonly used by business professionals with long-term commitments in Thailand, such as employees of Thai companies and foreign investors.

The Non-Immigrant B Visa is issued under two main categories, depending on the applicant’s purpose of stay.

1. Conducting Business (Investment & Business Activities)

  • This category is for foreign business owners, investors, and individuals involved in business negotiations, meetings, and other professional activities in Thailand.

  • Sponsorship from a Thai company is required, which includes submitting company-related documents during the application process.

2. Employment (Working for a Thai Company)

  • This visa is for foreign nationals seeking employment in Thailand.

  • It is necessary to have a job offer from a Thai company, and the employer must provide required sponsorship documents.

  • A work permit is mandatory for legal employment—holding a Non-Immigrant B Visa alone does not permit work.

Applying for a Non-Immigrant B Visa involves multiple steps, depending on whether you’re applying from abroad or within Thailand.

  • Submit an application at a Thai embassy or consulate in your home country or a neighboring country.

  • Pay the applicable visa fee:
    • 2,000 THB for a Single-Entry visa.
    • 5,000 THB for a Multiple-Entry visa.

  • Wait for processing (typically 5–10 business days).
  • Enter Thailand using the visa.
  • If employed, apply for a Work Permit at the Thai Ministry of Labor.
  • For long-term employment, extend the 90-day visa to a 1-year stay after obtaining the work permit.

To successfully obtain a Thailand Business Visa, you need to meet specific requirements and submit the necessary documents.
