How we help
Frequently asked questions
Who is the Non-B Business Visa for?
It's for people who need legal work status in Thailand: professionals employed by a Thai company, founders setting up a Thai business, and investors or directors. The Non-B lets you be employed by, or operate, a Thai company.
How long is the visa valid, and how often do I renew?
The Non-B starts at 90 days and can be extended to a full year once you're set up in Thailand. From there it renews annually, and Gateway Siam manages the renewals and reporting for you.
Do I need a work permit as well as the visa?
Yes — to work legally you need the Non-B visa paired with a Thai work permit; one without the other isn't enough. We structure the visa and work permit together and file with both the Ministry of Labour and immigration so the two stay aligned.
What documents and company requirements are involved?
You'll typically need an employment contract or company registration, the company's financial and tax documents, your qualifications and CV, plus a valid passport and photos. Because the company side also has to meet financial and staffing ratios, we prepare that documentation for you — book an assessment and we'll map out your exact case.
