BOI & Foreign Business Setup Lawyer in Prachinburi — 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 Prachinburi
Prachinburi is an overlooked heavy-industry base, centred on the 304 Industrial Park and the Kabin Buri corridor. Its plants run to paper, electronics and chemicals, which means the legal work does not end at labor: it takes in factory operating licences, capacity expansions, environmental conditions, and the contractor agreements for crews working inside the plant.
A plant that is running production cannot wait on uncertainty, so we say plainly at the outset which issues are fixed with paperwork, which need negotiation, and which genuinely have to go to court — with a timeline given before work starts.
