Understanding Non-B visa requirements, work permit processes, and ongoing compliance obligations is essential for any foreigner planning to work or conduct business in Thailand. This comprehensive guide explains everything you need to know about obtaining and maintaining legal work authorization in Thailand.


I/ Understanding Non-B Visa Thailand Requirements

The Non-Immigrant Business visa, commonly called the Non-B visa, allows foreign nationals to enter Thailand for business purposes, employment, or entrepreneurial activities. This visa category serves as the prerequisite for work permit applications and long-term business operations.

Types of Non-B Visas

1. Single Entry Non-B Visa

Valid for 90 days from entry, single-entry Non-B visas suit short-term business visits or initial company setup activities. These visas cost approximately 2,000-3,000 Thai Baht and can be obtained from Thai consulates worldwide.

2. Multiple Entry Non-B Visa

Multiple entry visas allow unlimited entries during the validity period, typically one year. Each entry permits 90-day stays, making them ideal for business people requiring frequent travel between Thailand and other countries.

3. Extension of Stay

Non-B visa holders can apply for one-year extensions of stay based on employment or business activities. These extensions require work permits and employer sponsorship, with annual renewal requirements.

Key Eligibility Requirements

Educational Qualifications

Most Non-B visa applications require bachelor's degree certification or equivalent professional qualifications. Specific industries may have additional educational requirements, particularly in healthcare, education, and technical fields.

Financial Requirements

Applicants must demonstrate adequate financial resources to support themselves during their stay. Bank statements showing consistent balances of 20,000-40,000 Thai Baht (or equivalent foreign currency) for 3-6 months typically satisfy financial requirements.

Criminal Background Checks

Clean criminal records from home countries are mandatory for Non-B visa applications. Police clearance certificates must be recent (within 6 months) and properly authenticated by relevant embassies or consulates.

Health Certificates

Some Non-B visa applications require health certificates confirming applicants are free from prohibited diseases. Medical examinations must be conducted by approved physicians or medical facilities.


II/ Thai Business Visa Application Process

Application Locations

Non-B visas can be obtained from Thai embassies and consulates worldwide, with processing times and requirements varying by location. Some applicants prefer applying from neighboring countries like Laos, Cambodia, or Malaysia for faster processing.

Required Documentation

1. Passport and Photographs

Valid passports with minimum six months remaining validity and adequate blank pages for visa stamps. Recent passport-style photographs meeting Thai embassy specifications are required.

2. Company Documentation

Letters of invitation from Thai companies, business registration certificates, and company profiles demonstrating legitimate business relationships or employment offers.

3. Educational Certificates

Academic transcripts, degree certificates, and professional qualifications relevant to the intended work or business activities in Thailand.

4. Financial Evidence

Bank statements, employment letters, or other financial documentation proving adequate resources for the intended stay duration.

Processing Times and Costs

Standard Non-B visa processing takes 2-5 business days, depending on the consulate and application complexity. Expedited processing may be available for additional fees.

Visa fees range from 2,000-5,000 Thai Baht for single entry visas, with multiple entry visas costing 5,000-8,000 Thai Baht. Additional document authentication and courier fees may apply.


III/ Work Permit Requirements and Application Process

Work permits authorize foreign nationals to engage in specific employment activities in Thailand. All foreigners working in Thailand must obtain work permits, regardless of visa status or employment duration.

Company Requirements for Hiring Foreigners

Minimum Capital Requirements

Thai companies must maintain minimum registered capital to hire foreign employees. Generally, companies need 2 million Thai Baht registered capital for each foreign worker, though some industries have different requirements.

Thai Employee Ratios

The standard requirement mandates employing four Thai nationals for each foreign worker. However, certain industries, educational institutions, and Board of Investment companies may have exemptions or reduced ratios.

VAT Registration

Companies hiring foreign workers typically must register for Value Added Tax (VAT) with the Revenue Department. This requirement applies to most businesses expecting annual revenue exceeding 1.8 million Thai Baht.

Work Permit Application Documentation

1. Personal Documents

Valid passport with Non-B visa, educational certificates, criminal background checks, health certificates, and recent photographs meeting Department of Employment specifications.

2. Company Documents

Company registration certificates, VAT registration, financial statements, tax registration documents, and evidence of Thai employee employment with social security contributions.

3. Employment Contracts

Detailed employment agreements specifying job duties, salary, working conditions, and other terms of employment meeting Thai labor law requirements.

4. Supporting Evidence

Organizational charts, office lease agreements, business licenses, and other documentation demonstrating legitimate business operations and employment necessity.


IV/ Sponsored Non-B Visa and Work Permit Services

Many foreigners find the Non-B visa and work permit process overwhelming, particularly when establishing new businesses or relocating to Thailand. Sponsored services provide comprehensive solutions for obtaining work authorization without the complexity of managing the process independently.

What Are Sponsored Work Permits?

Sponsored work permit services involve established Thai companies providing employment sponsorship for foreign nationals seeking work authorization. These arrangements allow foreigners to obtain Non-B visas and work permits without establishing their own companies initially.

Benefits of Sponsored Services

1. Simplified Process

Sponsored services eliminate the need to establish Thai companies, navigate complex bureaucracy, or manage ongoing compliance requirements independently.

2. Faster Processing

Established sponsoring companies have existing relationships with agencies and streamlined processes that accelerate visa and work permit approval.

3. Compliance Assurance

Professional sponsoring companies ensure all documentation meets current regulatory requirements and maintain ongoing compliance with changing regulations.

4. Cost Predictability

Sponsored services provide fixed pricing for visa and work permit processes, eliminating unexpected costs or bureaucratic delays that can increase expenses.

V/ Non-B Visa Extension and Work Permit Renewal

Non-B visa extensions require valid work permits, employer sponsorship, and evidence of ongoing employment or business activities. Extensions are granted for one year and must be renewed annually before expiration.

Required Documentation for Extensions

2. Company Compliance

Work Permit Renewal Process
