The Board of Investment’s Thailand Investment and Expat Services Center or TIESC was officially inaugurated on 31 March 2025. The Prime Minister of Thailand, Prime Minister Paengtongtarn Shinawatra has presided the official launch of TIESC and it is located on the 6th and 7th floors of One Bangkok’s Parade Zone, Rama IV Road in Pathumwan district.
TSIEC aims to increase convenience by offering faster services on investment and visa & work permit services formerly offered by the One Stop Investment Center and the One Stop Service for Visa and Work Permit. It also brings together the Board of Investment (BOI), Immigration Bureau and the Department of Employment in one place to facilitate access to investment consultation, government liaison, and long-term investment support for targeted investors and provide smooth visa and work permit support for skilled professionals and expatriates working in Thailand.
TIESC’s services on the 7th floor include the BOI’s One Start One Stop (OSOS) which offers consultation to investors on Thailand’s investment incentives, laws, regulations and procedures as well as coordination with government and private sectors to facilitate business operations for both existing and new investors, and the Expatriate Services Division which offers end-to-end support for foreign professionals by providing information, guidance and processing services for BOI’s Visa, LTR and Smart Visas.
TIESC’s services on the 6th floor include One Stop Service for Visa and Work Permit which is a branch of the Immigration Bureau that processes various applications for eligible users such as visa extensions, change of status, residence permits and 90-day notification reporting as well as the Department of Employment which handles applications for work permits and employment notifications for foreign nationals working for the BOI-promoted companies and other eligible groups such as branch offices and Representative Offices.
The integration of electronic systems through the Single Window for Visa and Work Permit makes TIESC services efficient because it allows users to submit and track applications online via a unified platform which eliminates the need for separate submission to different agencies. This inter-agency connectivity streamlines procedures, reduces redundancy and increases the speed and transparency of government services.
We at Thai Lawyers provide business start-up service for getting BOI promotion, visa & work permit applications or branch office and representative office registrations. With the BOI’s TIESC, we ensure that each process will be done smoothly and effectively.
