Hey! Iโve got a 60 day tourist visa on my passport, I want to stay in Thailand for 90 days. When do I have to apply for he 30 day extension, and, will I get 30 days from my last day on the 60 day period or from the day the extension gets approved??? Thanks!
TLDR : Answer Summary
You can apply for a 30-day extension of your tourist visa at most Immigration offices any time between 30 days before your current visa expires and the last day of your admitted stay. The additional 30 days will be added to your current 60-day period, meaning your total stay could extend to 90 days.
