Overview

The Non-Immigrant B visa is for foreign nationals working in Thailand under employment contracts. It is the standard visa category for foreign employees and business owners who have secured employment with a Thai company.

The Non-B visa is distinct from other visa types because it requires both employer sponsorship and a separate work permit issued by the Ministry of Labour. The visa allows you to enter and stay in Thailand for employment purposes, while the work permit authorizes you to actually perform work.

Important: Holding a Non-B visa alone does not authorize you to work. You must also obtain a work permit before starting any employment. Both documents must be renewed annually.

Key Considerations

Employer Cooperation

Essential for both initial application and annual renewal

Annual Work Permit Renewal

Work permit must be renewed annually — do not let it lapse

Single Employer Only

Cannot work for other employers without a new work permit

90-Day Reporting

Required every 90 days at your local immigration office

Working without a valid work permit is illegal. Even with a valid Non-B visa, performing work without an active work permit can result in fines, deportation, and re-entry bans. Always ensure both documents are current.

Common Mistakes to Avoid

Working without a work permit

Holding a Non-B visa alone does not authorize employment. You must also obtain a work permit from the Ministry of Labour before starting any work.

Forgetting annual work permit renewal

Both the visa and work permit must be renewed annually. Letting either expire invalidates your legal right to stay and work in Thailand.

Changing employers without a new permit

Each work permit is tied to a specific employer. You cannot work for another company without applying for a new work permit.

Missing 90-day reports

Non-B holders must file TM47 every 90 days. Missing this can result in a ฿2,000 fine and complications at renewal.

After Getting Your Non-B Visa

Your Ongoing Compliance Obligations

Holding a Non-B visa means you have several ongoing obligations beyond just the visa itself.

90-Day Reporting (TM47)

Every 90 Days

File every 90 days — required for all Non-B holders

Re-Entry Permit

Before Travel

Get one before travelling abroad — or your visa is cancelled
