ORIGINAL POSTERTLDR : Answer Summary
You can typically apply for a SETV extension 30 days before your current 60-day visa expires. The extension will add 30 days to your existing 60-day period, which means that if you extend your visa towards the end of the initial 60 days, you will have a total of 90 days in Thailand.
