First-party answers on Thai work authorisation: the standard Department of Employment route, BOI and IEAT channels for skilled experts, US company rights under the Treaty of Amity, and the APEC Business Travel Card for Thai nationals — including which supporting documents must be translated and legalised first.

Which comes first, the visa or the work permit?
In the usual sequence, the foreign national first holds a non-immigrant visa consistent with the intended employment, then applies for a work permit under the law on managing the employment of foreign workers, administered by the Department of Employment. Continued stay afterwards is decided separately by the Immigration Bureau. The three systems are distinct but interlocking, and a gap in one blocks the next.
Do I need a work permit for remote work for a foreign company?
This is fact-specific. The law addresses work performed within the Kingdom rather than only the location of the payer. Visas designed for remote workers carry their own conditions and do not automatically confer the right to work for a business in Thailand. Where Thai clients or a Thai entity become involved, obtain advice before starting to avoid regulatory exposure.
Can dependants of a work-permit holder work?
Permission to stay as a dependant and permission to work are separate matters. Dependants admitted on the basis of the principal's status do not gain an automatic right to work; they need an employer and their own work permit application under the normal criteria. Children entering school require a separate process, including certified translations of academic records.
Which authority decides a work permit, and what does it not cover?
The Department of Employment under the Ministry of Labour administers work authorisation for foreign nationals; the Immigration Bureau separately administers the right to stay. A work permit does not extend your permission to stay, and a valid visa does not authorise work. Both must be kept aligned, because expiry of one commonly triggers problems with the other at the next renewal.
What happens to the permit if I change employer or job title?
Authorisation is granted by reference to the employer, workplace and described duties, so a change in any of them normally requires a filing rather than a private arrangement. Continuing to work under the old permit after the change is treated as unauthorised work. Plan the change with the new employer before resigning, because the gap between employments also affects the underlying permission to stay.
What must be done when changing employer or job title?
A work permit is tied to the conditions recorded in it, including employer, position and place of work, so material changes must be notified or amended under the applicable law before working under the new conditions. Changing employer also usually affects employment-based permission to stay, so the two processes should be planned together. Typical documents are a letter from the new employer, corporate registration papers and the new employment contract; verify the current procedure with the Department of Employment.
Is a work permit the same as a visa in Thailand?
No. A visa such as Non-Immigrant B is issued by a Thai embassy or consulate, extensions of stay are approved by the Immigration Bureau, while the work permit itself is issued by the Department of Employment under the Emergency Decree on Managing the Work of Aliens B.E. 2560 (2017). Holding a valid visa does not by itself authorise employment, and working before authorisation carries legal penalties, so both tracks must be planned together.
How are foreign degrees and experience letters handled?
They usually must be translated into Thai or English as required and legalised through the diplomatic chain: certified in the issuing country (apostille where that country is a Convention party), then endorsed by the Royal Thai Embassy, or endorsed by that country's embassy in Thailand and then legalised by the Legalization Division of the Department of Consular Affairs before submission.
