Thai work permit — company-side and employee-side documents
Work permits are issued by the Department of Employment and are tied to the employer, position and workplace. Changing job, role or location requires a new filing.
Documents to prepare
- Company side: current affidavit, shareholder list, financial statements, social security filings
- Employee side: passport, the correct visa category, and the required medical certificate
- Degrees and experience letters, legalised at source and translated for Thai use
- Employment contract and job description
- Workplace map and photographs where requested
- Power of attorney for the company's filing agent
Step-by-step procedure
1. Check company and role eligibility
Registered capital, Thai-to-foreign staff ratio and reserved occupations are verified first.
2. Prepare foreign documents
Qualifications and experience letters must be legalised abroad and translated before filing.
3. File the application
Through the Department of Employment, or a dedicated channel such as the BOI One Stop Service.
4. Collect and comply
Work only within the stated role and location, and renew before expiry.
Pitfalls to avoid
- Working outside the stated role or location breaches the permit conditions.
- A permit belongs to the employer — it cannot follow you to a new company.
- Visa and permit expire on different dates; track both.
- Company documents older than the accepted window must be reissued.
Advisory tips
- Set reminders at least 45 days before either expiry date.
- Maintain a standing company document pack to speed up future filings.
- BOI-promoted companies should use the dedicated channel to cut steps.
