Two permissions, one activity

Thai immigration permission answers why and how long a foreign national may stay. Work permission answers whether the person may perform the proposed work. A Non-Immigrant B visa is commonly used for employment, but it does not by itself authorise the person to start working. The Department of Employment’s e-WorkPermit system handles applications for qualifying non-immigrant residents and employer-filed applications for workers outside Thailand.

The Department of Employment's current portal confirms that qualifying non-immigrant residents use a work-permission application and separately lists changes affecting the permitted work. The linked decree PDF could not be retrieved during the 1 August 2026 review, so this page no longer relies on its exact definition of “work”. If an activity sits near the boundary—unpaid help, directorship duties, a Thai client, or mixed foreign and Thai customers—the Department of Employment is the deciding agency.

Thai employment: Non-B plus Department of Employment process

The Royal Thai Embassy in Budapest’s Non-B page, updated 11 February 2026, lists employment evidence such as company records, a signed employment letter or contract and WP3 approval or an existing work permit. It says the employment visa holder applies for the work permit after arrival if one is not already held. The Royal Thai Consulate-General in Savannakhet, updated 10 March 2026, states that its employment Non-B is valid for three months from issue and permits up to 90 days per entry.

Mission checklists vary. As checked on 1 August 2026, Budapest and Savannakhet publish differently worded evidence lists, and Budapest applies consular-jurisdiction rules. There is no safe universal “embassy packet”: use the current checklist of the mission serving the applicant’s residence, then use the Department of Employment’s requirements for the work application.

Corporate capital, Thai-staff ratios and document sets also vary with employer type, BOI status, treaty position and the application being made. They should not be presented as one universal formula. The employer or its authorised representative can check the company’s case with the provincial employment office before an employee relies on it.

DTV remote work: what the official pages support

The DTV’s workcation category accepts digital nomads, remote workers, foreign talent and freelancers. The Budapest embassy page, updated 11 February 2026, expressly says DTV holders cannot obtain a Thai work permit, work for Thai companies or freelance for Thai clients. It requests evidence appropriate to the applicant—such as a foreign employment contract, remote-work confirmation, company records or professional portfolio.

That official wording supports foreign-market remote work; it does not create a universal test for every mixed-client or Thai-facing arrangement. Where the customer, payer, contracting entity or delivered service is in Thailand, the Department of Employment should confirm whether work permission is required.

LTR work is not “permit-free”

Older summaries often say LTR holders do not need a work permit. The BOI’s current process is more precise. The LTR application timeline says an LTR holder working for an entity in Thailand must apply for permission immediately after LTR issuance or before employment starts. As of 1 August 2026, BOI states a digital work-permit application normally takes 3–5 working days after LTR issuance when documents are complete. Work-from-Thailand status for a qualifying overseas employer does not automatically authorise a separate Thai job.

Prohibited occupations still apply

A valid stay and work permission do not by themselves establish that every occupation is open to foreign nationals. The Department of Employment's linked English notification timed out during the 1 August 2026 review, so its detailed occupation groupings are not restated here as freshly verified. Confirm the actual duties and any professional-licence condition with the Department of Employment before relying on a job title alone.

When employment ends or duties change

There is no universal “seven-day grace period” published for every job-ending scenario. The employer’s work-permission cancellation, the basis of the employee’s extension of stay and the immigration office’s cancellation record are separate steps. A person whose job ends can confirm the exact cancellation date and any permitted stay directly with the Department of Employment and the immigration office that issued the extension. Starting a new role, employer, location or job description before the required update is approved can fall outside the existing permission.

Tax is a separate assessment

A visa label or work permit does not settle Thai tax residence, source of income or remittance treatment. See the Thai tax guide for an overview and verify a real filing position with the Thai Revenue Department or a qualified adviser. This page does not infer tax liability from a DTV, Non-B, SMART or LTR label alone.
