Teaching in Thailand: Visa and Work Permit Requirements

Complete guide to the Non-B visa, work permit, Teacher's Council license, degree requirements, and criminal background checks for foreign teachers.

Working Without Proper Documentation Is Illegal

Teaching without a valid work permit is a criminal offense under Thailand's Working of Aliens Act B.E. 2551 (2008). Penalties include fines of THB 5,000 to THB 100,000, imprisonment up to 5 years, deportation, and potential blacklisting from Thailand. Immigration conducts regular school inspections, and schools face severe penalties for employing undocumented teachers.

Thailand employs thousands of foreign teachers across government schools, private schools, international schools, language centers, and universities. While teaching positions are plentiful, the legal requirements to work as a teacher are specific and must be followed precisely. This guide explains every step of the legal pathway from visa application through maintaining your teaching career.

The requirements differ somewhat depending on whether you work at a Thai government school, a private Thai school, an international school, or a language center. However, the core requirement is the same: you need a Non-Immigrant B (Business) visa and a valid work permit before you can legally teach.

The Non-Immigrant B Visa for Teachers

The Non-Immigrant B visa (commonly called "Non-B" or "Non-B visa") is the visa category that allows you to enter Thailand for the purpose of employment. For teachers, this visa is typically obtained with the support of your employing school, which provides essential documentation.

Types of Non-B Visas

There are several variations of the Non-B visa relevant to teachers:

Non-B Visa Application Documents

  • Valid passport: With at least 6 months validity and blank pages for stamps and visa sticker
  • Visa application form: Completed and signed, with recent passport photo
  • Letter from school: Official invitation letter from your employer, on school letterhead, specifying your position, salary, and employment dates
  • School documentation: Business registration, Ministry of Education license, and employer tax ID
  • Educational credentials: Degree certificates, often requiring authentication or apostille from your home country
  • Criminal background check: From your home country, typically authenticated and/or apostilled
  • Flight itinerary: Showing entry to Thailand (some consulates require this)
  • Visa fee: Varies by consulate and nationality (typically USD 80-200 for single entry)

Where to Apply

You must apply for your Non-B visa at a Thai embassy or consulate outside Thailand before arrival. The specific requirements vary by consulate, so contact the consulate serving your jurisdiction for their exact requirements. Processing typically takes 3-10 business days, though some consulates offer expedited processing for additional fees.

Work Permit Application Process

Once you enter Thailand on your Non-B visa, you must apply for a work permit before you can legally begin working. The work permit application is submitted to the Ministry of Labour's Department of Employment, and your school typically handles most of the paperwork.

The Work Permit Application Steps

1Arrive in Thailand on Non-B Visa

Enter Thailand using your Non-B visa. You will receive a 90-day permission to stay stamp. Do not begin teaching until your work permit is approved, even if you have the Non-B visa.

2Gather Required Documents

Collect all necessary documents including your original degree certificate, passport copies, photos, medical certificate from a Thai hospital, and documents from your employer. Your school should guide you through their specific requirements.

3Submit Application to Labour Office

Your school's representative typically submits the application to the provincial Labour Office or, in Bangkok, the One Stop Service Center for Visas and Work Permits. You may need to be present for the submission.

4Receive Work Permit Book

Upon approval, you receive a work permit book (blue booklet) specifying your employer, position, work location, and validity period. Processing typically takes 7-30 business days depending on the province and workload.

Work Permit Required Documents

  • Completed WP.1 form: Application form for work permit, signed by both you and your employer
  • Original passport: With valid Non-B visa and entry stamp
  • Passport copies: All relevant pages (data page, visa, entry stamps) certified by applicant
  • Photos: Recent photos (typically 3-6, size 3x4 cm, white background)
  • Educational documents: Original degree certificate plus certified copies; may require translation and authentication
  • Medical certificate: From a Thai hospital or clinic, certifying you are free from prohibited diseases (including leprosy, tuberculosis, elephantiasis, third-stage syphilis, drug addiction, alcoholism, and severe mental illness)
  • Criminal background check: Original document from your home country, typically requiring authentication/apostille and possibly Thai translation
  • Employment contract: Signed contract with your Thai employer
  • Employer documentation: Company registration, tax certificates, list of employees showing Thai-to-foreign worker ratio

Teacher's Council of Thailand License

Beyond the work permit, foreign teachers at Thai schools (both government and private) generally need a teaching license from the Teacher's Council of Thailand (TCT), also known as Khurusapha. This is a professional credential separate from your immigration-related work permit.

Who Needs a TCT License?

Temporary Teaching Permit

If you do not yet qualify for a full TCT license (for example, lacking required educational courses), you can apply for a Temporary Teaching Permit valid for 2 years. This allows you to teach while completing any missing requirements. The temporary permit can be renewed once, giving you up to 4 years to obtain full licensure.

TCT License Requirements

  • Bachelor's degree or higher: From an accredited institution (any field, though education degrees are advantageous)
  • Educational coursework: TCT requires certain credits in pedagogy, educational psychology, and related subjects. If your degree lacks these, you may need to complete additional courses or obtain a temporary permit while studying.
  • TEFL/TESOL certification: While not officially required for the TCT license itself, most schools require TEFL certification, and it demonstrates pedagogical training
  • Clean criminal record: No serious criminal convictions
  • Good moral character: Assessed through references and background checks
  • Thai language proficiency: Not strictly required for license, but increasingly expected by some employers

Degree Requirements and TEFL Certification

The educational requirements for teaching in Thailand have evolved over the years. While specific requirements depend on the type of institution, certain baseline qualifications are nearly universal.

Minimum Degree Requirements

Institution Type Minimum Degree TEFL Required? Notes
Government Schools Bachelor's degree Often required TCT license required; education degree preferred
Private Thai Schools Bachelor's degree Usually required TCT license usually required
International Schools Bachelor's degree minimum Depends on role Teaching certification from home country often preferred; higher salaries
Language Centers Bachelor's degree Usually required TEFL often essential; TCT license typically not required
Universities Master's degree often required Varies by position Academic credentials and publications valued

TEFL Certification

Teaching English as a Foreign Language (TEFL) or Teaching English to Speakers of Other Languages (TESOL) certifications are widely expected, even though not always legally mandated. Key considerations:

International Schools vs. Thai Schools

Understanding the differences between international schools and Thai schools is crucial for choosing your employment path, as the requirements, salaries, and working conditions differ significantly.

Factor Thai Government/Private Schools International Schools
Salary Range THB 30,000-50,000/month typical THB 80,000-200,000+/month
TCT License Required Often not required
Teaching Certificate Helpful but not always required Often required from home country
Experience Required Entry-level positions available 2-5+ years typically required
Benefits Package Basic; housing allowance rare Housing, flights, insurance common
Class Sizes 30-50+ students common 15-25 students typical
Curriculum Thai Ministry of Education curriculum IB, British, American, or other curricula

International School Accreditation

Legitimate international schools are typically accredited by organizations such as CIS (Council of International Schools), WASC, NEASC, or other recognized bodies. Accredited schools generally offer better salaries, benefits, and working conditions. Research school accreditation before accepting a position.

Criminal Background Checks

Criminal background checks are mandatory for work permit applications and teaching licenses. Thailand has become increasingly strict about this requirement following high-profile cases involving teachers with undisclosed criminal histories.

Obtaining Your Criminal Background Check

Authentication Requirements

Your criminal background check typically must be authenticated before Thai authorities will accept it. The process depends on whether your country is a member of the Apostille Convention:

Document Validity Periods

Criminal background checks are typically only valid for 3-6 months from the date of issue for Thai work permit and visa purposes. Plan your document timeline carefully to ensure your background check is still valid when you submit your applications. An expired background check will require you to obtain a new one.

Maintaining Legal Status

Once you have your Non-B visa and work permit, you must maintain your legal status through regular extensions and compliance with Thai law.

Annual Extensions

Changing Employers

If you change schools, you must update your work permit to reflect your new employer before starting at the new school. Working for an employer not listed on your work permit is illegal. The process involves:

  1. Obtaining a release letter from your current employer
  2. Having your new employer initiate a work permit transfer or new work permit application
  3. Reporting the change to Immigration if it affects your visa extension

Working During School Breaks

Your work permit is tied to your specific employer and position. Working for another school or employer during breaks (such as teaching at a summer camp for a different organization) would require a separate work permit or amendment to your existing permit. Private tutoring for extra income may also violate work permit restrictions depending on how it is structured.

Common Pitfalls to Avoid

Foreign teachers frequently encounter problems due to misunderstanding Thai requirements or making assumptions based on practices in other countries:
