What is a Thailand Business Visa (Non-Immigrant B Visa)?

The Thailand Business Visa (Non-Immigrant B Visa) is a special visa category that permits foreigners to enter Thailand for the purpose of employment, company management, or business investment. Unlike a tourist visa, the Business Visa explicitly allows work-related activities under Thai immigration law. This visa initially grants a 90-day stay, but can be extended to a one-year Business Visa Thailand, enabling you to stay long-term for business purposes. For official definitions and detailed guidelines, you can visit the Thai Immigration Bureau website.

Can I extend my Business Visa while in Thailand?

Yes, it is possible to extend your Business Visa Thailand (Non-Immigrant B Visa) after the initial 90-day period, provided that you meet all the necessary legal and administrative conditions. This extension is typically granted to individuals who are employed by a Thai company or conducting legitimate business operations in the country.

1. Extension Process and Requirements

To apply for the visa extension, you must visit the nearest Thai Immigration Office and submit a complete application. Your employer must provide an updated support letter confirming your current employment, position, salary, and the company’s intention to continue your engagement. Additionally, your company must prove it is compliant with Thai labor and tax regulations this includes submitting up-to-date corporate registration documents, tax filings, and evidence of social security contributions for Thai employees. You will also need to present your valid passport, current visa stamp, a completed TM.7 application form, and proof of financial stability. The government fee for processing the extension is currently 1,900 THB, though this amount may be subject to change.

2. Duration and Important Considerations

If approved, the extension transforms your initial 90-day visa into a One-Year Business Visa Thailand, allowing you to remain in the country without needing to leave and re-enter. However, it’s important to remember that even with this visa, you are still required to complete 90-day reporting at your local immigration office. It’s essential to understand that visa extensions are not guaranteed. Incomplete documentation or non-compliance by your sponsoring company can lead to a denied application. Moreover, applying late or overstaying your current visa can result in fines or even deportation. For the most accurate and current guidelines, consult the official Thai Immigration Bureau website.

Can I apply for a work permit with a Business Visa?

Yes, you can apply for a work permit in Thailand, but only after obtaining a Business Visa Thailand, officially known as the Non-Immigrant B Visa. This visa is a mandatory prerequisite for any foreigner who intends to work legally in the country. Once you have your valid Business Visa, you can submit a work permit application to the Thai Ministry of Labour, detailing your job title, employer information, and the nature of your responsibilities. Both the visa and the work permit are legally required; holding one without the other is not sufficient. Working in Thailand without proper authorization can lead to severe penalties, including fines, deportation, and blacklisting, which can affect your future travel or employment in the region. For accurate and up-to-date information on eligibility and the application process, consult the official Thai Ministry of Labour website.
