WORK IN THAILAND
Thailand Work Visa Non-B
A Thailand work visa is required for any foreign national intending to work or conduct business in the Kingdom. The process begins with an application for a Non-Immigrant Visa at a Thai Embassy or Consulate, with the Non-B (Business) category being the most common Thailand work visa issued to employees, directors, and company owners. Other categories, such as the Business Visit visa, may apply depending on the purpose of stay. A Thailand work visa alone does not authorise employment. A separate work permit, issued by the Ministry of Labour, is required before any work can lawfully be undertaken.

I was handling a complicated situation around Thai business compliance + immigration/Non-B visa process, with deadlines and a lot of moving parts. Their team stayed calm, explained things clearly, and gave me realistic options instead of false promises... ...

They know what they’re doing and they treat clients with respect.

FAQs
What is the difference between a Non-B visa and a work permit?
They are two different documents. The visa is issued by a Thai Embassy or Consulate and lets you enter and stay in Thailand. The work permit is issued by the Ministry of Labour and lets you work. You need both.
Can I apply for a Non-B visa before I have a job?
No. A Thai company has to sponsor the application, so you need a job offer or your own registered company before you start.
How long is a Non-B visa valid for?
The visa issued at the embassy lasts 90 days. Before it runs out we file an extension at Immigration, which turns it into a one year stay. After that you renew it each year.
Can I switch from a tourist visa without leaving Thailand?
Often, yes. The conversion is done at Bangkok Immigration. It depends on your nationality and on Immigration's decision, so we check whether you qualify first.
What happens if I change employer?
Your work permit is tied to one employer. When the job ends, the permit is cancelled and the visa extension that came with it ends too. It is much easier to move to a new sponsor before you resign than to start again afterwards.
Do I have to leave Thailand to renew each year?
No. The yearly extension is filed at Immigration here in Thailand. If you plan to travel during the year, get a re-entry permit before you go, or your permission to stay ends when you leave.
Can my family come with me?
Yes. Your spouse and children can apply for a Non-O dependent visa based on your status. It lets them live in Thailand but not work. If they want a job, they need their own visa and work permit.
Is the process different for a BOI-promoted company?
Yes. Staff of BOI-promoted companies go through the One Stop Service Centre, which is usually quicker than the standard route. The visa category can also be different.
