How to Apply for a Non-Immigrant B Visa (Non-B Visa) in Thailand

We assist foreign nationals in obtaining a Non-Immigrant B Visa in Thailand for employment, business, investment, or company management while ensuring compliance with Thai immigration and work permit regulations.

Introduction

Foreign nationals who wish to work, conduct business, or invest in Thailand must obtain a Non-Immigrant B Visa (Non-B Visa) before engaging in business or employment activities in the country.

The Non-B Visa is issued by Thai Embassies or Consulates abroad and allows foreign nationals to enter Thailand for the purpose of employment, business operations, investment activities, or company management. After entering Thailand with a Non-B Visa, the visa holder can apply for a work permit and extend their stay through the Thai Immigration Bureau.

Non-B Visas are commonly used by foreign employees, company directors, investors, and entrepreneurs establishing or operating businesses in Thailand.

UnionSPACE Visa & Immigration Team assists clients with the Non-B Visa application process, including preparing documentation, coordinating with Thai embassies, and guiding applicants through the immigration and work permit procedures.
