Non-Immigrant B Visa for Working in Thailand in Thailand
The gateway visa before a work permit — the employer's readiness matters as much as your own papers.
Quick answer
The Non-B is a temporary-stay visa for employment or business and is the base for a work permit from the Department of Employment. Annual extensions at immigration generally look at 2 million baht paid-up capital per foreign employee, four Thai staff, and a nationality-based minimum salary. Criteria change, so verify with the Immigration Bureau before filing. Contact our team for a quotation.

How it works
4-step process
- 1
Audit the employer
Most refusals trace back to the company — insufficient capital or missing tax filings — so we check before any fee is paid.
- 2
Obtain the Non-B
Apply at a Thai embassy or consulate abroad, or convert inside Thailand where the rules allow.
- 3
Apply for the work permit
Filed with the Department of Employment, with a job description matching the real duties.
- 4
Annual extension
Filed with immigration before expiry using the company's latest-year documents.
FAQ
Frequently asked questions
Can I start work as soon as I hold a Non-B?
No. The Non-B is only a visa; the work permit must be issued before you start. Working without one exposes both employee and employer to penalties.
What happens to the visa if I resign?
The employer must notify the termination, and permission to stay is usually cancelled. Plan a new employer or visa type before your last working day.
Do BOI companies follow the 2 million baht rule?
BOI-promoted companies generally file through the One Stop Service Center under their promotion conditions instead of the standard ratios.
