The non-immigrant B visa, also called the business visa in Thailand. There are two categories of the non-immigrant B visa, which are:

  1. Non-immigrant B visa (conducting business) issued to foreigners who wish to set up or conduct business in Thailand.

  2. Non-immigrant B visa (employment) issued to foreigners who intend to work in Thailand.


Foreigners can apply for either a single-entry visa (90 days non-immigrant visa) or a multiple-entry visa (one-year non-immigrant visa).


The single-entry visa is issued by the Thai embassy or consulate aboard or in your home country and allows a stay of 90 days.


The visa must be used within 90 days from the issuance date, and it grants the holder a 90-day stay inside Thailand. Once the visa has expired, it can be extended for an additional seven days.


Holders of the temporary 90-day non-immigrant visa usually use the visa to enter Thailand, apply for a work permit, and once the validity of the visa has run out, they can convert it into a long-term solution, for example, a one-year non-immigrant business visa, one-year business visa extension or others.

Requirements for the business visa


The general requirements for the business visa include:

  • A passport with at least six months validity from the date of your planned arrival in Thailand

  • An invitation or confirmation letter to clarify the purpose of travel issued by the concerned organisation

  • Additional supporting documents as requested by the Royal Thai Embassy or consulate

  • Proof of financial funds and travel itinerary

  • Embassy fee
