Visa & Work Permit Services

What Is a Visa?

A visa is generally permission granted to a foreign national to enter and remain in Thailand for a specific purpose and period of time.

Different visa categories exist depending on the intended purpose of stay, such as:

• tourism,
• business,
• employment,
• retirement,
• education,
• investment,
• or family-related purposes.

Holding a visa does not automatically permit a foreign national to work in Thailand.

Common Types of Thai Visas

Tourist Visa

A tourist visa is intended for tourism and short-term visits to Thailand. This type of visa is generally not intended for employment or business operations.

Non-Immigrant B Visa (Business Visa)

A Non-Immigrant B Visa is commonly used for:

• business-related activities,
• employment,
• corporate matters,
• or business operations in Thailand.

This visa category is often associated with foreign employees, directors, investors, and business owners. However, obtaining a business visa alone does not automatically grant permission to work in Thailand.

Retirement Visa

A retirement visa is generally intended for eligible foreign nationals who wish to retire and reside in Thailand long term. Specific eligibility and financial requirements may apply depending on the visa category.

Dependent or Family Visa

This type of visa may be available for spouses, children, or dependents of eligible visa holders in Thailand. Eligibility depends on the immigration status of the primary visa holder and supporting documentation requirements.

Education Visa

An education visa is generally intended for foreign nationals studying or participating in approved educational programmes in Thailand. The visa holder must comply with the conditions and purpose of the visa category.

Long-Term Resident and Special Visa Categories

Thailand also offers certain long-term or special visa categories for qualifying individuals, investors, highly skilled professionals, and other eligible applicants under specific programmes or regulatory frameworks.

What Is a Work Permit?

A work permit is legal authorisation allowing a foreign national to work in Thailand. Under Thai law, foreign nationals who intend to perform work in Thailand may be required to obtain a valid work permit before commencing work activities.

Importantly:

• a visa and a work permit are not the same thing,
• and in many cases, both may be required.

For example:

• a foreign employee may hold a Non-Immigrant B Visa,
• while separately obtaining a work permit authorising employment in Thailand.

Why Is the Difference Important?

One of the most common misunderstandings is the assumption that holding a business visa automatically permits employment.

In practice:

• a visa relates to immigration status and permission to stay,
• while a work permit relates to permission to work.

Foreign nationals and employers should therefore ensure that both immigration and employment requirements are properly addressed.

Can a Foreigner Work in Thailand Without a Work Permit?

In many cases, working in Thailand without proper authorisation may expose both the foreign national and the employer to legal and immigration consequences.

The definition of “work” under Thai law may be broader than many people expect. Activities that appear informal or temporary may still fall within regulatory requirements depending on the circumstances.

Proper legal and immigration planning is therefore important before commencing business or employment activities in Thailand.
