If you’re planning to work in Thailand through a company promoted by the Board of Investment (BOI), be aware that starting August 1, 2025, the Thai government is introducing a new mandatory registration process that will affect how companies manage work permits and visa applications.
The update applies to all BOI-promoted companies using the Single Window (SW) system, Thailand’s digital platform for work permit and visa processing. Even if your company already has an account, you’ll need to register a new user profile to continue using the system.
Understanding BOI Companies
These are companies promoted by Thailand’s Board of Investment for contributing to economic development. They enjoy certain benefits like fast-tracked visa/work permit processing and foreign ownership allowances.
What Is the Single Window System?
The Single Window system is Thailand’s digital platform that allows BOI-promoted companies to manage visa and work permit applications online. It integrates the Board of Investment, Immigration Bureau, and Department of Employment, enabling fast, paperless processing and real-time tracking of application status.
For companies employing foreign experts, this system is a game-changer, streamlining what used to be a complex, multi-agency process into a single, user-friendly interface.
What’s Changing in Thailand’s Work Permit Process?
1. New User Account Required: Existing users can’t continue without registering under the new setup. Every BOI-promoted company must create a fresh account under the updated registration protocol.
2. Digital Identity Verification: Thai representatives must verify their identity using the ThailD mobile application, a government-issued app for secure digital authentication.
- Foreign nationals need to complete their verification via email.
3. Deadline: Although no end date has been specified, starting August 1, access to the Single Window system will be restricted unless the new registration is complete.
4. System Access: Failing to register means companies risk losing access to the portal, which could delay work permits and visa applications for both Thai and foreign staff.

Who Needs a Work Permit?
Any foreigner planning to work in Thailand must obtain a work permit, regardless of their visa type. The work permit legally states the foreigner’s position, occupation, and employer, and is required by law for employment in the Kingdom.
How to Get One
You typically need a job offer from a Thai-registered company. The company applies on your behalf through the Ministry of Labour or via the BOI Single Window system (if eligible).
Processing Time
On average, it takes 7–10 working days for approval if all documents are in order.
Validity Period
Thailand’s Work permits can be issued for up to 2 years, often tied to the employment contract and visa status.
The Work Permit Application Process
- Obtain a Non-Immigrant Visa: Secure a non-immigrant “B” visa before entering Thailand.
- Prepare Documentation:
- Passport, medical certificate, degree certificate, employment letter, and photos.
- The employer must provide company documents, shareholder lists, VAT registration, and more.
- Submit Application: Apply at the Ministry of Labour or via the Single Window system if you’re with a BOI-promoted company.
- Wait for Approval: The process usually takes 7 days for standard applicants, but can be faster for BOI companies.
- Collect Your Permit: Once approved, collect the work permit in person and keep it with you at all times while working.
Special Perks for BOI-Promoted Companies
- Faster Processing: BOI companies benefit from expedited work permit and visa processing.
- Easier Renewals: The Single Window system simplifies renewals and status tracking.
- Attractive Incentives: BOI-promoted companies enjoy tax breaks, the ability to own land, and fewer restrictions on foreign ownership.
What Should Companies and Expats Do Now?
To avoid any disruption:
- BOI Companies: Complete the new user registration before August 1, 2025. Confirm that all Thai reps have the ThailD app installed and verified.
- Foreign Employees: Check in with your employer to ensure your visa and work permit process won’t be delayed.
- HR and Legal Teams: Test the updated Single Window system in advance and prepare documentation. Email-based verification for expats should be planned ahead of renewals or new applications.
Final Thoughts
Thailand is stepping up its digital game when it comes to work permits, but the transition could trip up companies that aren’t paying attention. With the August 1 deadline approaching, businesses and expats alike should treat this as a priority.
Whether you’re an HR manager at a BOI firm or a foreign worker renewing your permit, act now to stay compliant and avoid delays.
