I want to extend my 30 day holiday visa with another 30 days. How long before the 1st 30 days expires do I need to do this. The next question is will they add the 30 days as form the last day of my current visa.
Thank you.
TLDR : Answer Summary
To extend your 30-day holiday visa in Thailand by another 30 days, you can apply for the extension during the last week of your current visa validity. The additional 30 days will be added to the last day of your current visa. It is also important to ensure you have a TM30 filed with the Thai Immigration office.
