Professional licences, training certificates and experience letters
Applicants for overseas jobs or licences often submit professional licences, training certificates and employer experience letters. Each type enters a different certification path depending on who issued it.
The key distinction is who issued the document: a government agency, a professional council, or a private company. Licences from professional councils and certificates from government agencies can go straight into the consular legalisation chain. Privately issued documents such as employer experience letters need a Notarial Services Attorney to certify the signatory first.
An experience letter that actually works states the job title, the employment period with exact dates, a short description of duties, and the signatory's name and position. Many receivers reject letters that merely confirm employment without dates.
A certificate from a private training provider carries different weight from one issued by a regulator. Stating the course name, contact hours and the accrediting body on the certificate itself lets the receiver assess it without follow-up.
Translations here must use exact professional terminology, particularly job titles and the scope of a licence. Rendering a professional title more broadly or narrowly than the original can read as misrepresenting qualifications.
Full legalisation does not mean the destination country recognises a right to practise. Legalisation concerns the authenticity of signatures; the right to practise is decided by that country's regulator.
Documents to prepare
- Original professional licence and a copy
- Employer experience letter stating title and dates
- Training certificates with course details and contact hours
- The employer's company registration document if the receiver verifies the issuer
- The applicant's passport and Thai ID card
- Translations into English or the destination language for the whole set
Order of steps
- Separate government/professional-council documents from private ones
- Private documents: signature certification by a Notarial Services Attorney
- Translate into the destination language using precise professional terminology
- Certify the translation and legalise at the Department of Consular Affairs
- Add embassy certification, or file with the destination regulator under its own rules
Pre-filing checklist
- Check the experience letter states exact dates
- Check the signatory is authorised to sign for the company
- Check the licence is still valid on the filing date
- Check translated job titles match the original without embellishment
- Keep the issuer's contact details in case the receiver verifies
Frequently asked questions
Can a private company letter be legalised directly at the consular department?
Usually not. That department verifies signatures it holds specimens for, so private documents normally need a Notarial Services Attorney to certify the signature first.
Does a Thai professional licence allow me to work abroad?
A Thai professional licence does not automatically permit you to work in a foreign country. Document legalisation only confirms the authenticity of the licence, requiring professionals to apply for official recognition or complete board examinations under the destination country's regulatory rules.
My former employer has closed. What replaces the experience letter?
Supporting evidence such as withholding-tax certificates, social-security records or employment contracts can be used; the receiver weighs the evidence case by case.
Translate into English or the destination language?
Follow the receiver's requirement. Some countries accept only their official language; others accept English. Check before translating to avoid doing it twice.
Are online training certificates accepted?
Online training certificates are accepted depending on the specific evaluation criteria of the receiving organisation. Certificates that explicitly detail the training provider, course name, completed contact hours, and an official verification pathway are significantly more likely to be accepted by reviewing authorities.
Must the set be re-legalised for every job application?
Not always, but many receivers set a validity window on the certification, so check each receiver's rule before reusing an older set.
