Thailand's Visa and Work Permit One-Stop Center Moved to One Bangkok and Became TIESC

Anyone who has renewed a BOI-linked visa, extended a work permit, or processed an LTR application in Bangkok in recent years is likely familiar with the one-stop service center that previously operated out of Chamchuri Square. On March 17, 2025, that office relocated to the sixth and seventh floors of the Parade Zone at One Bangkok, the large mixed-use development on Rama IV Road in Pathumwan, and was rebranded as the Thailand Investment and Economic Service Center, TIESC. The center was formally inaugurated on March 31, 2025, with then-Prime Minister Paetongtarn Shinawatra presiding over the launch event.

What TIESC Actually Does

TIESC integrates three previously separate government service functions under one physical location: the BOI's One Start One Stop Investment Center, which handles BOI promotion-related matters, the Immigration Bureau's visa services, and the Department of Employment's work permit processing. Rather than a foreign professional or BOI-promoted company needing to visit separate offices, or separate counters within a larger building, for BOI, immigration, and labor matters, all three functions now operate from the same location at One Bangkok.

This is confirmed directly by the BOI's own One Start One Stop Investment Center portal, which describes the new center's integrated function, alongside independent reporting from Khaosod English on the March 31 inauguration and a client alert from Fragomen, a major global immigration law firm, flagging the relocation and its accompanying processing considerations for clients with pending applications.

Why a Physical Relocation Is Worth Its Own Entry

It would be easy to dismiss a government office relocation as administrative trivia not worth separate coverage. But for anyone who has an in-progress BOI-linked visa extension, a work permit renewal tied to a BOI-promoted employer, or an LTR application moving through this specific office, knowing the correct physical location, and building in the disruption a mid-process relocation can cause, is directly practical information. Fragomen's client alert specifically flagged expected processing delays around the relocation window, since any government office move involves a period where staff, records, and systems are being physically transferred, a detail that matters to anyone whose application happened to be in process during March 2025.

The Current Location

TIESC now operates from One Bangkok, Parade Zone, 6th and 7th floors, 1877 Rama IV Road, Lumphini, Pathumwan, Bangkok 10330, reachable from the MRT Lumphini station (Exit 1) or BTS Ploen Chit station (Exit 2). Anyone still directing visa or work permit correspondence, or planning an in-person visit, to the former Chamchuri Square location is working from outdated information.

What This Means in Practice

For a BOI-promoted company or an individual LTR, Non-B, or BOI-linked visa holder needing to visit this office for an extension, renewal, or new application, the practical takeaway is simple: confirm the current One Bangkok location rather than relying on older guidance that still references Chamchuri Square, and factor in that this integrated, single-location model is designed to reduce the number of separate government offices a BOI-linked applicant needs to visit, not increase it. Anyone whose visa or work permit matter touches BOI promotion status should expect this office, not a standalone Immigration Bureau or Department of Employment counter, to be the relevant point of contact.

This entry is intentionally shorter than a typical DeeMED update article. The underlying event, a one-time office relocation and rebranding, is narrow and does not carry the same depth of downstream implications as a substantive rule change; padding it further would overstate its significance rather than serve a reader who simply needs the current, correct location and context.
