This article provides an overview of the extension of the business visa in Thailand.

If you wish to extend your stay in Thailand, you may consider applying for a business visa extension, which, unlike the one-year business visa, does not require you to leave the country.

Read on to find out the requirements for the extension.

Regulations regarding the business visa extension

Regulations that must be met in order to obtain the business visa extension are:

  • The company must:
    • Be registered in Thailand
    • Have a ratio of four Thais for every foreigner (4:1)
    • Have a paid-up capital of THB 2 million
    • Have net equity equal to THB 1 million
    • Show revenue of the previous year, including the salary of all employees
    • Submit the previous year’s profit and loss account, which must be certified by a certified accountant
  • The applicant must:
    • Have a valid Thai work permit
    • Earn a minimum salary in accordance with the amount specified for each nationality

The above conditions are only applicable to non-BOI (standard) companies.

The following entities have relaxed the requirement for the 4:1 Thai national ratio and extensions can be made with a 1:1 ratio:

  • International trade business (representative office)
  • Regional office
  • International companies (branch office)
  • BOI-promoted limited company
