Written by the Thai Legal & Immigration legal team · Last reviewed · Editorial policy
Your work permit describes a specific job, employer and place of work. If you are promoted, transferred to a new branch, or begin working at another site, the permit must be amended — working outside its description is treated as unauthorised work.
Changing to a completely new employer is not an amendment: it requires a new permit and usually a new visa basis. We identify which situation applies and file accordingly.
What we handle
- Review of the proposed change.
- Amendment filing for job title or workplace.
- Additional workplace authorisation.
- Advice on employer change and visa impact.
