What the One Stop actually is
A single Bangkok centre, at Chamchuri Square, where the Immigration Bureau and the Labour Ministry sit side by side processing the affairs of BOI-promoted and similarly privileged companies. Where the standard track means separate agencies, weeks of lead time and annual anxiety, the One Stop processes extensions and permits in hours against the company's standing BOI approval. The practical ceiling on frustration in a promoted company's expat programme is simply lower by design.
Who gets the door code
- BOI-promoted companies, for positions approved within their promotion.
- Companies under IEAT and petroleum regimes, and regional-headquarters structures.
- LTR visa holders, whose digital work permits run through the same centre.
- Large-capital conventional companies meeting the centre's thresholds, ฿30 million paid-up being the historical marker.
How positions work
The unit of approval is the position, not the person. The promoted company files its foreign-position structure with the BOI, justifying each role's necessity; approved positions can then be filled and refilled through the e-Expert system with the individual's qualifications reviewed against the slot. Salaries must meet the published floors by nationality and seniority, and the famous four-to-one Thai ratio does not govern promoted positions, which is frequently the single most valuable sentence in the whole regime for a knowledge business.
The rhythm in practice
- New hire: e-Expert position approval, then a single One Stop visit for visa transfer and digital work permit, commonly completed within a day or two of arrival.
- Annual renewals: filed and stamped at the centre, the whole household's extensions synchronised.
- Dependants: processed alongside the principal in the same visit.
- Changes, employer moves within the group, role changes: amendments rather than restarts.
The centre processes what the BOI has approved; it does not debate. Files that stumble do so at the e-Expert position stage, where the company's headcount story must convince. Draft the position rationale as carefully as the promotion application itself.
Planning implications
For a venture weighing BOI promotion at the margin, the One Stop is often the deciding weight: the tax holiday expires, but the immigration lane does not. For principals, it converts the most tiresome annual ritual of Thai life into an administrative errand. We assess One Stop eligibility as part of every corporate structuring we do, and for qualifying clients we build the expat programme around it from the first hire.
