If you’re working in Thailand or running a business here, you’re likely familiar with the Non Immigrant B Visa. But what happens when your initial visa period is about to expire? That’s where Non B Visa extensions come into play. Let’s dive into the details of this crucial process for expatriates in the Land of Smiles. 

What is a Non B Visa Extension? 

A Non B Visa extension is exactly what it sounds like it’s a way to prolong your stay in Thailand beyond the initial visa period. Typically, a Non B Visa is valid for 90 days upon entry. The extension allows you to remain in the country for a longer duration, usually up to one year. 

Why You Might Need an Extension 

There are several reasons why you might need to extend your Non B Visa: 

1. Your work contract extends beyond the initial visa period 

2. You’re involved in a long-term business project in Thailand 

3. You’re teaching or working in education with a year-long contract 

4. Your business in Thailand requires a longer stay 

The Extension Process: What You Need to Know 

Applying for a Non B Visa extension isn’t overly complicated, but it does require careful preparation. Here’s what you need to do: 

1. Gather Required Documents: These typically include: 

  • Your passport with the current Non B Visa 
  • Completed extension application form (TM.7) 
  • Recent passport-sized photographs 
  • Proof of address in Thailand (such as a lease agreement) 
  • Letter from your employer or evidence of your business in Thailand 
  • Work permit (if applicable) 
  • Tax documentation 

2. Visit the Immigration Office:  

You’ll need to submit your application in person at your local Thai Immigration office. 

3. Pay the Fee:  

There’s an official government fee for the extension. Be prepared to pay this when you submit your application. 

4. Wait for Processing:  

Processing times can vary, but it’s usually completed within a few weeks. 

5. Collect Your Extended Visa:  

Once approved, you’ll receive a stamp in your passport indicating the new expiration date. 

Important Considerations 

90-Day Reporting: Even with an extended visa, you’re required to report your address to Immigration every 90 days. 

Re-Entry Permits: If you plan to travel internationally during your extended stay, you’ll need to obtain a re-entry permit before leaving Thailand. 

Timing is Crucial: Start the extension process well before your current visa expires. It’s recommended to begin at least a month in advance. 

Work Permit Correlation: Ensure your work permit (if required) aligns with your visa extension dates. 

Seeking Professional Help 

While it’s possible to handle the Non B Visa extension process yourself, many expatriates choose to use a visa agency in Thailand. These agencies can help navigate the paperwork, ensure all documents are in order, and sometimes even expedite the process. While there’s an additional cost involved, many find the peace of mind worth the expense. 

The Bottom Line 

Extending your Non B Visa is a crucial step in maintaining your legal status in Thailand if you’re staying for work or business beyond the initial 90-day period. By understanding the process and requirements, you can ensure a smooth extension and continue your Thai adventure without unnecessary stress. 

Remember, immigration rules can change, so it’s always a good idea to check the most current requirements with the Thai Immigration Bureau or a reputable visa agency before starting your extension process.
