What is the Thailand Visa Extension Guide?
Extend your tourist, visa exemption, or non-immigrant visa at any provincial immigration office.
Extending your stay in Thailand is a routine process that hundreds of thousands of visitors complete every year at Thailand's provincial immigration offices. Whether you are on a tourist visa, a visa exemption stamp, or a longer-stay non-immigrant visa, the extension process follows the same general pattern: visit the immigration office, fill in TM.7, pay the fee, wait, and receive a new stamp in your passport.
The extension available depends on your current visa type: tourist visas and visa exemptions can be extended once for 30 days (฿1,900); non-immigrant visas (retirement, education, business) are extended for one year. Some people use extensions alongside re-entry permits to create continuous long-term stays without returning to an embassy. Understanding the immigration office procedures, required documents, and common pitfalls makes the process significantly smoother.

Step-by-Step Process
Find your nearest immigration office
Use the Thai Immigration Bureau website (immigration.go.th) to find the office with jurisdiction over your area. In Bangkok, Chaeng Wattana is the main office. Major provincial cities have their own offices. Many immigration offices are closed on Thai public holidays.
Prepare your documents and photos
Have your passport, TM.7 form (fully completed), one 4×6 cm photo, photocopies of your passport pages, and ฿1,900 in cash ready. Some offices have copiers on-site but the queues are long.
Take a queue number
At the immigration office, take a number for the extension queue. Wait for your number to be called. Depending on the day and office, waits can range from 20 minutes to several hours.
Submit your application
Present your documents to the officer. They will review everything and may ask questions about your stay. Pay the ฿1,900 fee and receive a receipt.
Wait for your passport to be stamped
Your passport may be taken away for processing (30 minutes to a few hours at busy offices). You will receive a slip with a return time. Collect your passport with the new extension stamp.
Check your new stamp
Before leaving the office, verify the 'permitted to stay until' date stamped in your passport. If there is an error, raise it immediately — errors are almost impossible to correct once you leave.
Expert Tips
- Go on a Tuesday or Wednesday — Monday and Friday are the busiest days at most offices.
- Some large provincial offices offer appointment booking online — check the office website to save queuing time.
- Consider using an immigration agent for ฿500–1,500 extra to avoid queuing. This is legal and common, especially in Pattaya, Phuket, and Chiang Mai.
- Dress respectfully — shorts and sleeveless tops are sometimes turned away at Thai government offices.
Common Mistakes to Avoid
- Forgetting to bring cash — most immigration offices do not accept cards.
- Bringing the wrong photo size (e.g., 3×4 cm instead of 4×6 cm).
- Not making photocopies of passport pages before arriving.
