Applying for BOI investment promotion in Rayong — what paperwork is needed?

This question is specifically about “Applying for BOI investment promotion in Rayong”, so the answer below starts with what this case actually needs before setting out the general rules. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. With a fixed filing date, count backwards from it and book each certification step in reverse. Note who signed each certification and on what date for later reference. If the receiving body confirmed its requirements by email, keep that message with the file. Once the set is complete, check it line by line against the destination's own checklist before filing. The specifics here are location: Rayong, and those decide which translation and certification level applies. The terms that frame this page are Applying · investment · promotion · Rayong. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. Before starting, verify the source document is still within any validity window the recipient applies, then count the number of certified sets needed before work starts, because extra sets restart the certification steps, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation. Companies are registered with the Department of Business Development (DBD), Ministry of Commerce: a private limited company is formed under the Civil and Commercial Code and a public limited company under the Public Limited Companies Act B.E. 2535 (1992), with a memorandum of association, articles and a shareholder list among the incorporation papers. Foreign documents used in a work permit or incorporation file — degrees, experience letters, the parent company's certificate of incorporation, powers of attorney and passports — must be translated into Thai or English as the office requires and certified along the correct chain: certification in the country of origin, then embassy or Department of Consular Affairs legalisation as applicable. ILC handles the document side only — certified translation, notarial signature certification and legalisation runs at the Department of Consular Affairs or an embassy. ILC is not the deciding authority and cannot guarantee an approval. Cost and lead time depend on page count, language pair and the certification steps the receiving authority requires, so every file is quoted before work starts.
