If you plan to work in Thailand through a company supported by the Board of Investment (BOI), be aware that starting August 1, 2025, the Thai government is introducing a new mandatory enrollment system. This change will directly affect how companies manage work permits and visa applications.
The update applies to all BOI-promoted firms using the Single Window (SW) system, Thailand’s digital platform for work permit and visa processing. Even if your company already has an account, you must register a new user profile to continue using the system.
