Non-B
Thailand Business & Work Visa (Non-Immigrant B) — Guide
The Non-Immigrant B is the standard visa for foreigners employed by, or doing business with, a company in Thailand. It works together with a work permit from the Department of Employment; the visa lets you stay, the work permit lets you work.

FAQ
Can I attend meetings in Thailand without a Non-B?
Short business meetings are generally allowed on visa exemption, but any activity that counts as work needs a work permit.
What if I change employers?
The new employer must obtain a new work permit and extension; plan the timing with both employers before resigning.
