If you’re planning to start a business, work for a Thai company, or invest on Koh Phangan or Koh Samui, the Non-Immigrant “B” Visa (often called the “Non-B”) is usually your starting point. Here’s what it involves.
What Is the Non-B Visa?
The Non-B visa is designed for foreigners entering Thailand for business or employment purposes. It’s the visa category most closely linked to working legally in the country, and it’s typically a prerequisite before you can apply for a Work Permit.
Who Is It For?
- Foreign business owners setting up or running a Thai-registered company
- Employees hired by a Thai company or branch office
- Investors involved in a Thai business
- Freelancers or consultants with a formal employment or service arrangement with a Thai entity
Types of Non-B Applications
- Single Entry — valid for 90 days, useful for initial setup before switching to a longer visa
- Multiple Entry — valid for one year, allowing multiple trips in and out of Thailand during that period
- Extension of Stay — once in Thailand, the visa can usually be extended annually at the local Immigration Office, provided the business and employment requirements are still met
Basic Requirements
Requirements vary depending on whether you’re an employee or a business owner, but generally include:
- A Thai company sponsoring the visa, with valid registration documents
- Minimum registered capital (commonly 2 million THB for foreign-employee applications)
- A set ratio of Thai employees per foreign staff member the company sponsors
- Supporting documents such as the company’s shareholder list, financial statements, and tax records
- A clear job description matching the role being sponsored
Non-B and Work Permit — Two Separate Steps
Getting a Non-B visa doesn’t automatically allow you to work — it only allows you to apply for a Work Permit, which is a separate process through the Ministry of Labour. Both need to stay valid and aligned; letting one lapse can create problems for the other.
Common Challenges on the Islands
Setting up a compliant business structure on Koh Phangan or Koh Samui — with the right capital, staffing ratios, and paperwork — can be more complex than it looks, especially for smaller businesses like dive shops, guesthouses, restaurants, or wellness centers. Missteps here are a frequent cause of delayed or rejected applications.
Renewing Your Non-B Visa
Extensions are generally tied to the continued operation of the sponsoring business and must be renewed annually, alongside your Work Permit. Immigration officers may request updated company documents, tax filings, or proof of ongoing business activity at each renewal.
Getting Started the Right Way
Because the Non-B visa sits at the intersection of company law, tax compliance, and immigration rules, it’s one of the visa types where getting professional guidance early can save significant time and cost. A local legal advisor can help structure your business correctly from the start and keep your visa and work permit in good standing.
