BOI & Foreign Business Setup Lawyer in Sing Buri — 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.
