Thailand Work Permit Requirements
To legally work in Thailand, a foreigner must hold a work permit issued by the Ministry of Labour. The permit is a legal document stating your position, current occupation, employer, and permitted workplace. Before the work permit application, you need a non-immigrant visa obtained prior to entering Thailand. Both applicant and employer submit separate document packs to the Department of Employment.
This checklist covers every document typically requested in 2026. Lists change when labour officials update regulations, so verify against Ministry of Labour and Department of Employment before submission. For quota rules and post-approval obligations, see our work permit basics guide.
Obtain non-immigrant visa before entering Thailand for employment in most cases.

Six-step application process
Secure Non-Immigrant B visa abroad
Apply at Thai consulate or through Thailand e-Visa with employer invitation, WP3 pre-approval where required, and company supporting documents. Enter Thailand on the employment visa, not tourist exemption.
Complete medical examination
Visit approved clinic for work permit medical certificate. Tests typically cover general fitness, syphilis, and substance screening. Keep original certificate for submission.
Gather applicant and employer packs
HR compiles company registration, tax, and office documents while you prepare passport copies, photos, degree certificates, and signed employment contract. Cross-check job title against Alien Employment Act restrictions.
Submit to Department of Employment
Employer or authorised representative files at provincial or central DOE office. Processing time varies from several days to weeks depending on location and completeness.
Collect work permit booklet
Once approved, work permit states employer name, job description, and office location. You may work only within permitted scope. Carry permit during working hours.
Extend visa at Thai Immigration
After work permit issuance, extend non-immigrant visa to align with permit validity. Maintain 90-day reporting and TM30 address registration throughout employment.
Visa first, permit second
The non-immigrant visa must be obtained before entering Thailand in standard employment cases. Apply through Thailand e-Visa or your regional Thai consulate with employer support.
Common document mistakes
- Submitting tourist visa or exemption stamp instead of non-immigrant visa. Work permit applications are rejected without correct visa category.
- Photos wrong size or older than six months. Labour officials reject applications for photo specification failures.
- Medical certificate expired before submission. Clinics typically issue certificates valid 30 days only.
- Job title on contract does not match work permit application or visa invitation letter.
- Company documents older than six months where fresh Commercial Registration certification is required.
- Missing VAT or withholding tax evidence when company should be registered and filing.
- Starting employment before permit is physically issued. Probation does not exempt you from permit requirements.
Frequently asked questions
Q:What visa do I need before applying for a work permit?
A:You need a non-immigrant visa, typically Non-Immigrant B for employment, obtained before entering Thailand. The work permit application follows after entry with employer sponsorship. Tourist visas and exemption stamps are not sufficient.
Q:What documents must the applicant submit?
A:Applicant pack includes Tor. Thor. 2 application form, passport, three 5x6 cm photos, medical certificate, degree certificates, employment agreement, Thai address proof, and CV when relevant. Officials may request additional documents for specific occupations.
Q:What documents must the employer provide?
A:Employer supplies company certificate, shareholder list, VAT registration, withholding tax records, financial statements, office map, director identification, and employment letter stating position and salary. Documents must be current and certified where regulations require.
Q:How long does work permit processing take?
A:Typical processing ranges from one to three weeks after complete submission at the Department of Employment. Visa processing abroad adds additional time. BOI-endorsed companies may receive faster handling.
Q:Do I need a medical certificate for a work permit?
A:Yes. Approved clinics issue medical certificates confirming fitness for employment. Certificates include standard health screening and are usually valid for about 30 days from examination date.
Q:Can I apply for a work permit while on visa exemption?
A:Generally no for new employment. You should enter on a non-immigrant visa arranged before travel. Limited exceptions exist for specific change-of-status scenarios, but planning employment from tourist entry is high risk and often denied.
Q:Must degree certificates be translated?
A:Non-English or non-Thai documents typically require certified translation. Some occupations require credential verification or professional licence from Thai regulatory bodies in addition to degree copies.
Q:Who submits the work permit application?
A:The Thai employer or authorised representative submits to the Department of Employment. Foreign employees provide personal documents but do not file independently without employer participation.
