Everything you need to know about work permits and visas for Thailand

Updated on April 25, 2025

Navigating the requirements for foreign nationals seeking to live and work in Thailand involves understanding a structured system of visas and work permits. Generally, a foreign individual intending to work in Thailand must first secure an appropriate non-immigrant visa from a Thai embassy or consulate abroad, or in some specific cases, apply for a change of visa status while already in Thailand. This visa typically serves as the initial entry clearance and establishes the legal basis for the individual's stay.

Following entry with the correct visa, obtaining a work permit is a mandatory separate process. The work permit is the official document issued by the Ministry of Labour that grants a foreigner the legal right to perform specific work for a designated employer in Thailand. Both the visa and the work permit are essential for lawful employment, and the processes are closely linked, often requiring employer sponsorship and adherence to specific criteria related to the job, the employer, and the foreign national's qualifications.

Common Visa Types for Foreign Workers

Several visa categories permit foreign nationals to work in Thailand, with the most common being the Non-Immigrant B (Business) visa. Other options cater to specific skills or investment levels.

  • Non-Immigrant B (Business) Visa: This is the standard visa for individuals coming to Thailand for business purposes, including employment. It requires sponsorship from a Thai company or organization.

    • Eligibility: Requires a valid passport, proof of financial stability, and supporting documents from the sponsoring company in Thailand (e.g., company registration, business license, list of shareholders, tax documents). The applicant's qualifications must match the job description.
    • Duration: Initially issued for 90 days (single entry) or one year (multiple entry). It can be extended annually within Thailand based on continued employment.
    • Purpose: Allows entry for business meetings, negotiations, or employment. A work permit is required to legally work after entry.
  • SMART Visa: Introduced to attract highly-skilled professionals, investors, executives, and startups in targeted industries. It offers benefits like a longer validity period (up to 4 years), exemption from the work permit requirement (the visa itself acts as the work permit), and fewer reporting obligations.

    • Eligibility: Strict criteria based on income, qualifications, investment amount, or position within a company operating in targeted industries (e.g., automotive, electronics, tourism, agriculture, biotechnology, digital, medical). Requires endorsement from relevant government agencies.
    • Duration: Up to 4 years, depending on the category.
    • Purpose: Facilitates entry and work for specific high-value individuals without needing a separate work permit.
  • Long-Term Resident (LTR) Visa: A relatively new visa category aimed at attracting wealthy global citizens, wealthy pensioners, highly-skilled professionals, and remote workers. It offers a 10-year renewable visa, exemption from the 90-day reporting requirement, and the ability to work in Thailand (for highly-skilled professionals and remote workers) without a separate work permit (though notification to the Department of Employment is required).

    • Eligibility: Varies significantly by category (e.g., minimum income/investment, specific industry experience, employer requirements for remote workers).
    • Duration: 10 years, renewable.
    • Purpose: Provides long-term residency and work authorization (for certain categories) to attract specific groups of foreigners.
Visa Type Primary Purpose Typical Initial Validity Work Permit Required? Key Benefit
Non-Immigrant B Business/Employment 90 days / 1 year Yes Standard route for general employment
SMART Visa Skilled/Investor/Exec Up to 4 years No (Visa acts as WP) Longer validity, streamlined process
Long-Term Resident Long-term stay/Work 10 years No (Notification req.) Extended residency, various categories

Work Permit Application

Obtaining a work permit (Book 3) is a separate process from getting a visa and is managed by the Department of Employment. It is typically applied for after arriving in Thailand with a valid Non-Immigrant B visa, although in some cases, it can be processed concurrently or applied for from abroad.

  • Eligibility: Requires a valid non-immigrant visa (usually Non-B), a sponsoring employer in Thailand, and qualifications that match the job description. The employer must meet specific criteria regarding registered capital, number of Thai employees per foreign employee, and business type. Certain professions are reserved for Thai nationals.
  • Sponsorship: The Thai employer is responsible for sponsoring the work permit application and providing necessary company documentation.
  • Documentation: Required documents include the applicant's passport and visa, educational certificates, professional licenses (if applicable), health certificate, photos, and extensive documentation from the sponsoring company (business registration, list of shareholders, tax returns, VAT registration, location map, etc.).
  • Procedure: The application is submitted to the Department of Employment. The process involves reviewing the applicant's qualifications and the employer's eligibility.
  • Processing Time: Can vary depending on the location and complexity, typically ranging from 7 to 30 working days.
  • Fees: Application fees vary based on the duration of the work permit requested (e.g., a one-year work permit costs approximately THB 3,000).

Pathways to Permanent Residency

Permanent Residency (PR) in Thailand is difficult to obtain and is subject to strict quotas and eligibility criteria.

  • Eligibility: Generally requires holding a Non-Immigrant visa for at least three consecutive years prior to the application, having a strong record of contributing to Thailand (e.g., through employment, investment, or family ties), meeting specific income requirements, and demonstrating knowledge of the Thai language and culture. There are different categories for application, including business/work, investment, humanitarian reasons (family ties), and expert categories.
  • Procedure: Applications are typically accepted only once a year, usually towards the end of the year, and are submitted to the Immigration Bureau. The process is lengthy and involves extensive documentation, interviews, and background checks.
  • Quota: A strict annual quota applies to each nationality, making the process highly competitive.
  • Processing Time: Can take from several months up to a year or longer.
  • Fees: Application fees are substantial, typically in the range of THB 100,000 to THB 200,000 or more upon approval.

Dependent Visa Options

Foreign nationals working in Thailand on a valid Non-Immigrant B visa and work permit can typically sponsor their immediate family members (spouse and children) for dependent visas.

  • Visa Type: Family members usually apply for a Non-Immigrant O (Other) visa based on their relationship to the primary visa holder.
  • Eligibility: Requires proof of the relationship (marriage certificate, birth certificates), the primary visa holder's valid Non-Immigrant B visa and work permit, and proof of the primary visa holder's stable income.
  • Procedure: Applications are usually submitted at a Thai embassy or consulate abroad or, in some cases, can be processed as a change of visa status within Thailand.
  • Duration: Dependent visas are typically issued for the same duration as the primary visa holder's extension of stay, usually one year, and must be extended concurrently.
  • Work Rights: Holders of dependent visas (Non-Immigrant O based on family) are generally not permitted to work in Thailand unless they obtain their own work permit, which usually requires changing their visa status to Non-Immigrant B and meeting the standard work permit requirements.

Visa Compliance Obligations

Both employers and employees have significant obligations to ensure compliance with Thai immigration and labour laws.

  • Employer Obligations:

    • Sponsor the foreign employee's work permit application.
    • Ensure the foreign employee holds a valid visa and work permit for the duration of their employment.
    • Notify the Department of Employment within 15 days if the foreign employee resigns or is terminated.
    • Maintain records related to the foreign employee's employment, visa, and work permit.
    • Adhere to the ratio of Thai employees to foreign employees as stipulated by law.
    • Comply with all labour laws, including minimum wage, working hours, and benefits.
  • Employee Obligations:

    • Hold a valid visa and work permit at all times while working in Thailand.
    • Only perform the work specified in the work permit for the designated employer and location.
    • Report to the Immigration Bureau every 90 days if staying in Thailand for an extended period.
    • Notify the authorities of any changes in personal information or employment status.
    • Carry the work permit and passport/visa at all times for inspection.
    • Adhere to the terms and conditions of their visa and work permit.

Failure to comply with these regulations can result in significant penalties, including fines, deportation for the employee, and legal action or business restrictions for the employer. Utilizing an Employer of Record service can help companies navigate these complexities and ensure full compliance.
