Hello, I am coming on a 60 day visa and wish to extend this an additional 30 days. Can this be done straight away, i.e I arrive and apply for the extension. Or do I need to wait until the end of my 60 day period?
Thankyou
TLDR : Answer Summary
You can apply for a 30-day extension for your 60-day visa immediately upon arrival in Thailand. Most offices allow this extension, but be aware that some locations like Jontiem may require you to wait until closer to the end of your 60-day period.
