Working under a Long Term Resident (LTR) visa — what should you know about the BOI One Stop Service channel?

The scope of this answer is “Working under a Long Term Resident (LTR) visa”, so it separates what is specific to this file from the standard certification chain. High-resolution photos of seals and signatures help when the destination asks for re-verification. Keep a copy of every source document plus the receipt or docket from each step. After certification, scan the full set before it leaves your hands. The terms that frame this page are Working · under · Long · Term. What changes the timeline most here is whether the source documents are complete on day one. The most frequent cause of delay in this group is missing supporting documents on the first submission. Before starting, make sure document numbers, issue dates and issuing-office names match across the set, then keep a digital copy of every page, including seals and signatures, then plan the timeline so certification finishes before the real filing deadline. Plan the schedule with room for at least one review cycle at the receiving office. Documents with a short validity window should be produced as close to the filing date as possible. Businesses promoted by the Board of Investment (BOI) or located in IEAT industrial estates may use the One Stop Service Center for Visa and Work Permit and the BOI e-Expert / Single Window systems, a channel separate from filing at a provincial employment office. Work by foreign nationals in Thailand is governed by the Royal Decree on Managing the Work of Aliens B.E. 2560 (2017) as amended by Decree No. 2 B.E. 2561 (2018); work permits are issued by the Department of Employment, Ministry of Labour. 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.
