BOI & Foreign Business Setup Lawyer in Si Racha — Incorporation, FBL, Treaty of Amity, EEC
Setting up a foreign-controlled business in Thailand routes through one of several systems: a Thai limited company with up to 49% foreign ownership (the default under the Foreign Business Act), a BOI-promoted company that can be 100% foreign-owned for promoted activities, a Foreign Business Licence (FBL) for activities outside BOI scope, the US Treaty of Amity (for US persons), or an EEC-zone structure. Each carries different timelines, costs, tax positions, and ongoing reporting. We help foreign investors pick the right path before anyone signs a lease, and we then run the incorporation and post-incorporation compliance.

About our team in Si Racha
Si Racha hosts Thailand's largest Japanese community outside Bangkok and the Pinthong and Saha Group industrial estates. Legal work here is factory work: employment contracts and work rules that have to cover Thai staff and foreign management alike, sub-contracting and automotive supply-chain agreements, work permits and visas for foreign staff, and the leases and condominium purchases of families posted here for years at a time.
We cover the Eastern seaboard from our Bangkok branch — meeting clients at the plant and appearing regularly at the Chonburi Provincial Court. We work in Thai, English and Chinese, which suits factories where management and HR do not share a first language.
