Working in Thailand
Foreigners can work legally in Thailand when they hold a valid non-immigrant visa, a Ministry of Labour work permit, and a job that does not violate the Alien Employment Act. Tourist stamps, visa exemption entries, and most retirement visas do not authorise employment. Remote work from a Bangkok cafe for a foreign employer still triggers immigration scrutiny when performed without the correct visa category.
This guide explains the visa-permit sequence, occupations reserved for Thai nationals, BOI exceptions, and compliance steps employers and expats must follow. For document lists, see our work permit requirements guide and work permit basics guide.
Both a valid non-immigrant visa and Ministry of Labour work permit are required for most employment.
Lists occupations reserved for Thai nationals and sets employer sponsorship rules.
Obtained before entry with employer support. Tourist stamps do not authorise work.
Work permits issued through Department of Employment under Ministry of Labour.
Legal framework: Alien Employment Act
Thailand regulates foreign employment through the Alien Employment Act and supporting Ministry of Labour regulations. The law defines which occupations are reserved for Thai nationals and sets penalties for unpermitted work. Both the foreign employee and the Thai employer can face fines, imprisonment, and deportation for violations.
Work permits are issued by the Department of Employment under the Ministry of Labour. Visa categories are managed separately by Thai Immigration and consulates under Ministry of Foreign Affairs policy. Your visa and work permit must describe the same employer and job function.
Five-step visa and work permit path
| Step | Action | Detail |
|---|---|---|
| 1. Job offer | Thai employer or BOI company extends written offer | Position must not fall under reserved occupations. Salary and role stated in employment letter. |
| 2. Non-Immigrant B visa | Apply at Thai consulate or e-Visa before entry | Employer provides invitation letter, company documents, and WP3 where required. |
| 3. Enter Thailand | Activate visa at immigration counter | Present passport, visa, and supporting documents. Stamp must match employment category. |
| 4. Work permit application | Employer submits to Department of Employment | Medical certificate, photos, degree certificates, and company filings required. |
| 5. Visa extension | Extend stay at Thai Immigration after permit issued | Work permit and visa must remain aligned. Report address changes within required timelines. |
Occupations reserved for Thai nationals
The Alien Employment Act closes dozens of job categories to foreigners. The table below summarises major groups. The full statutory list is longer and includes niche crafts and traditional trades. Always verify your exact job title with HR and the Department of Employment before accepting an offer.
| Category | Examples of reserved work |
|---|---|
| Manual labour and agriculture | General labour, bricklaying, carpentry, farm work (except specialised roles), fishing boat labour |
| Retail and sales | Front shop sales, auction work, hawking, tour guiding, brokerage (except international trade) |
| Personal services | Hairdressing, beautification, dressmaking, shoe and hat making |
| Traditional crafts | Wood carving, lacquer work, Thai musical instruments, Buddha images, silk weaving by hand |
| Transport (non-specialist) | Driving motor vehicles without machinery (except international aircraft pilots) |
| Professional services (reserved) | Accountancy services (except occasional internal audit), architectural design work, clerical/secretarial work |
Tourist visa vs employment: what is allowed
| Activity | Tourist stamp OK? | Work authorisation | Notes |
|---|---|---|---|
| Holiday sightseeing | Yes | No | Visa exemption or tourist visa (TR) sufficient. |
| Remote work for foreign employer | No | DTV or proper visa | Tourist stamps do not cover remote employment performed in Thailand. |
| Teaching at Thai school | No | Non-B + permit | Employer sponsors visa and work permit. Teacher licence may also apply. |
| Company director (active role) | No | Non-B + permit | Passive investment may use other visa types. Active management requires work authorisation. |
| Unpaid volunteering with local pay | No | Permit may apply | Any compensated activity can trigger work permit requirements. |
| BOI-promoted specialist | No | BOI + permit | Board of Investment companies may follow streamlined permit procedures. |
Compliance checklist for employees
Verify occupation eligibility
Cross-check your job title against the Alien Employment Act reserved list. Employers sometimes advertise roles foreigners cannot legally hold. Confirm with HR and immigration counsel before relocating.
Secure visa before travel
You must obtain a proper non-immigrant visa from a Royal Thai Embassy or Consulate, or through Thailand e-Visa, before arrival for employment. Converting from tourist exemption inside Thailand is limited and often not available for new employment.
Complete medical and document pack
Work permit applications require medical certificates, passport photos, degree verification, and Thai address proof. Employers supply company registration, VAT filings, and shareholder lists.
Align visa and permit validity
Work permit expiry, visa stamp, and 90-day reporting obligations must stay synchronised. Set calendar reminders for renewals at least 60 days before expiry.
Report changes promptly
Job title, employer, or address changes require work permit modification and immigration notification. Working outside permitted scope is a common enforcement trigger.
Plan departure on resignation
Return work permit to the Department of Employment within seven days of resignation. Employers and employees share compliance duties until cancellation is recorded.
Employer responsibility
Thai companies must meet capital and Thai-employee ratio quotas before hiring foreigners, unless a BOI or treaty exception applies. Employers submit company registration, tax filings, and office maps with each work permit application.
See work permit basics for quota details and exceptions.
Common mistakes and enforcement risks
- Working on tourist visa exemption or TR stamp, including remote work for a foreign company while physically in Thailand.
- Accepting a role in a reserved occupation such as front-shop retail, tour guiding, or general clerical work.
- Starting work before work permit approval. Even probationary duties can violate the Alien Employment Act.
- Assuming marriage to a Thai citizen automatically grants work rights without a permit.
- Using a DTV or retirement visa for full-time employment with a Thai employer.
- Ignoring 90-day reporting and visa extension deadlines while focused on work permit renewal only.
- Freelancing or consulting without employer sponsorship when the client relationship constitutes employment under Thai law.
Frequently asked questions
Q:Are foreigners allowed to work in Thailand?
A:Yes, if you hold a valid non-immigrant visa, a work permit issued by the Ministry of Labour, and employment in an occupation not reserved for Thai nationals under the Alien Employment Act. All three conditions must be met simultaneously.
Q:Can I work remotely in Thailand on a tourist visa?
A:Tourist visa and exemption stamps are for tourism. Performing remote work while physically in Thailand may violate immigration rules even if your employer is abroad and pays you overseas. Consider the Destination Thailand Visa (DTV) or another category that matches your activity.
Q:What occupations are closed to foreigners?
A:The Alien Employment Act reserves dozens of occupations for Thai nationals, including general labour, front-shop sales, tour guiding, hairdressing, traditional crafts, and clerical work. Specialized roles, management positions, and BOI-promoted jobs may qualify when quotas and documentation are satisfied.
Q:Do I need a visa before I can get a work permit?
A:Yes. You need a non-immigrant visa obtained before entering Thailand in most employment cases. The work permit application follows after entry and employer document submission to the Department of Employment.
Q:Can my Thai spouse sponsor my work permit?
A:Marriage to a Thai citizen supports certain visa options but does not replace the work permit requirement for employment. You still need employer sponsorship and Ministry of Labour approval for the specific job.
Q:What happens if I work without a permit?
A:Penalties include fines, deportation, and re-entry bans for both employee and employer. Immigration crackdowns periodically target bars, schools, and startups employing unpermitted foreign staff.
Q:Does BOI promotion change work permit rules?
A:Board of Investment companies may benefit from streamlined visa and work permit procedures and exemptions from certain quota calculations. The foreign employee still needs valid work authorisation, but processing can be faster with BOI endorsement.
Q:Where can I verify current work permit policy?
A:Check the Ministry of Labour and Department of Employment official portals, Thailand e-Visa for visa categories, and Ministry of Foreign Affairs for consular requirements. Rules change; confirm within weeks of your start date.
