A business in Chonburi dealing with applying for BOI investment promotion — which documents start the file?

The point raised here is “A business in Chonburi dealing with applying for BOI investment promotion”, so the answer below starts with what this case actually needs before setting out the general rules. The specifics here are location: Chonburi, and those decide which translation and certification level applies. The terms that frame this page are business · Chonburi · dealing · applying. Check first whether the issuing office of the source document is one the destination recognises. The common failure in this group of cases is a translation that does not match the certification type required. Before starting, count the number of certified sets needed before work starts, because extra sets restart the certification steps, then verify the source document is still within any validity window the recipient applies, then check that names are spelled identically to the passport or ID card on every page. With a fixed filing date, count backwards from it and book each certification step in reverse. Public holidays and embassy closures move certification queues more than most people expect. Attach a document index to the bundle so nothing is lost during review. Note who signed each certification and on what date for later reference. When filing for a company, attach current evidence of signing authority. Arrange supporting documents in the order the authority specifies to reduce rejections. If any requirement is still unclear, send a sample image to the receiving body before producing the full set. Investment promotion runs under the Investment Promotion Act B.E. 2520, administered by the Board of Investment (BOI), which grants incentives by promoted activity category. A promoted project can also obtain a Foreign Business Certificate through the BOI route. Operating inside an industrial estate falls under the Industrial Estate Authority of Thailand Act B.E. 2522. Eligible categories and conditions are revised periodically, so always check the current BOI announcement. A Thai corporate document used overseas is normally translated in full — including seals and signatures — then the translation is certified by the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, and finally by the destination country's embassy or consulate where that country requires it. Thailand is not a party to the 1961 Apostille Convention, so no apostille is issued for Thai documents. Forms, attachment lists and lodgement channels change from time to time. This page explains the legal framework and the document steps in general terms; before you act, re-confirm the current form, the supporting documents and the deadline with the licensing authority itself. Cost and lead time depend on page count, target language, how many certified sets are required and the steps the receiving authority sets, so every file is quoted before work starts.
