Hello, I got 30 days visa exemption stamp a couple of days ago. Is that possible to extend it for another 30 days any time or I need to wait more close to the expiration date of this stamp?
TLDR : Answer Summary
You can apply for a 30-day extension of your visa exemption stamp at a local immigration office in Thailand. It's recommended to apply closer to the expiration date of your current stamp, but you can do so anytime before it expires.
