Whether you’re starting a business, taking on a new job, or relocating as a foreign professional in Thailand, two essential documents are required: the Non-Immigrant Type B (Non-B) Visa and a Thailand Work Permit. This guide outlines the steps, requirements, and key insights to help you navigate the application process smoothly in 2025.
What is a Non-B Visa?
The Non-B Visa is issued to foreign nationals who intend to work or conduct business in Thailand. It is typically valid for 90 days initially and can be extended to a one-year stay once the work permit is secured.
Who Needs It?
- Foreign employees hired by a Thai company
- Business owners or directors of a Thai company
- Foreigners conducting business or attending meetings in Thailand
What is a Work Permit?
The Work Permit is a legal document that allows a foreigner to work in Thailand. Even with a valid visa, you cannot legally work without a work permit issued by the Ministry of Labour.
Important Note:
You must apply for a work permit after entering Thailand with the correct visa (typically Non-B) and before starting any work activity.
Digital vs. Physical Work Permit:
The digital work permit system is currently available only for foreign employees under BOI-promoted companies. For most other cases, the traditional blue work permit booklet is still used and remains legally required for employment, banking, and other official processes.
Step-by-Step Guide to Apply for Non-B Visa & Work Permit
Step 1: Secure a Job or Register Your Company
Before applying, you must have a confirmed job offer from a registered Thai company or have your own company legally established.
Step 2: Prepare the Required Documents
For the Non-B Visa application:
- Passport with at least 6 months validity
- An employment contract or company documents
- Company registration and shareholder list
- Business license and latest financial statements
- Invitation letter from the company
- Education qualifications and resume
For the Work Permit application:

Step 3: Apply for the Non-B Visa
Submit your Non-B visa application at a Thai Embassy or Consulate in your home country or outside Thailand. The initial visa is usually valid for 90 days.
Step 4: Enter Thailand & Apply for Work Permit
Once you arrive in Thailand, submit your work permit application at the Ministry of Labour. Upon approval, you will receive a blue work permit booklet (unless working under BOI).
Step 5: Extend Your Visa
After your work permit is approved, you can apply for a one-year visa extension based on your employment.

Frequently Asked Questions
1) Can I only have a work permit without a Non-B Visa?
No, you cannot apply for a work permit unless you hold a Non-B Visa. These two go hand-in-hand.
The only exception is if you are married to a Thai national and hold a Non-O (Marriage) Visa, in which case a work permit may be issued.
2) Can you help with all the documents and apply for me?
Yes! At Act & Align Advisor, we offer full-service assistance to prepare documents, file applications, and represent you throughout the process. You focus on your work — we’ll handle the paperwork.
3) What is the personal income tax if I’m holding a Non-B Visa & Work Permit?
Thailand Personal Income Tax (PIT) Rates (Progressive):
Annual Income (THB) | Tax Rate |
0 – 150,000 | Exempt |
150,001 – 300,000 | 5% |
300,001 – 500,000 | 10% |
500,001 – 750,000 | 15% |
750,001 – 1,000,000 | 20% |

2,000,001 – 5,000,000 | 30% |
