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. (19+ search topics covered)
Must authorisation be obtained before starting work?
Yes. A foreign national must hold the permit before performing work, and may only do the role, for the employer and at the locations stated in the permit. Trial periods and side assignments outside that scope are not covered. Changes of employer, position or workplace require notification or amendment through the Department of Employment.
Who can obtain an APEC Business Travel Card?
The card facilitates business travel among participating APEC economies and is issued to Thai business people by the Department of Consular Affairs, subject to endorsement by the designated authorities. Pre-clearance for each economy is decided by that economy, and the card does not grant the right to work abroad.
What must an employer prepare for a first foreign hire?
Typically current company records — registration certificate, shareholder list, financial statements and tax filings — together with social security registration for employees and an employment contract whose job title and scope match the permit sought. Ratio requirements for Thai employees or minimum registered capital may apply under the rules in force, so the corporate structure should be reviewed before filing begins.
How are foreign degrees and experience letters used for a Thai work permit?
They are normally authenticated by the competent authority in the issuing country and by the Royal Thai Embassy there, or by apostille once the Convention enters into force for Thailand on 28 February 2027 where accepted, then translated into Thai and legalised by the Department of Consular Affairs. Experience letters should state the position, exact dates, duties and the issuer's contact details, because verification enquiries do occur. Confirm the document list with the Department of Employment or the receiving office before preparing the file.
What does the BOI channel change?
Promoted companies can request approved skilled or expert positions through the BOI e-Expert system and complete visa and work permit formalities at the One Stop Service Center. Conditions and validity depend on the promotion certificate and the approved position, so a company should confirm its certificate conditions before planning foreign headcount.
How do we get exact fees and timelines?
Processing times and official fees vary by application type, receiving office, document completeness and local queues, so fixed figures on a web page would be misleading. Our team quotes case by case after reviewing the actual documents — contact us by phone, LINE or email.
What happens if the permit lapses while renewal is pending?
Renewal must be filed before expiry within the period set by the regulations, and the permitted-to-stay end date must be tracked alongside it because the two dates do not always coincide. A lapse can force a restart and affect immigration status. Set calendar reminders several weeks ahead and keep current employer documents ready before the deadline.
Why are Thai work permit applications commonly returned?
The usual reason is that the job title and duties in the application do not match the employer's supporting documents, such as the company affidavit, financial statements and employment contract. Other frequent causes are qualifications claimed without properly certified translations, and applying under a business activity that is not among the objectives registered with the Department of Business Development. Map every document to the same set of facts before filing and confirm the current requirements with the Department of Employment office responsible for the workplace.
