There is a minimum number of days you have to have left on your current stamp to apply for the in country Non-O visa. In Bangkok you need a minimum of 15 days, in Chiang Mai you need a minimum of 21 so you need to get after it.
There is no wiggle room on this, you have the required days left on your entry stamp (visa exempt or tourist visa) or the 30 day extension from it or you don't get to apply for the in country Non-O visa
