How early can I apply for a 30-day extension on my 60-day visa exempt in Bangkok?

I went early denied me,said come on the last week of the 60

Okay in BANGKOK you can apply for a 30 day extension when you have 45 days or less left on your current stamp

So with a stamp that runs out on the 30th of Dec you can apply any time from Nov 15th onward

You cannot go to "any office" (like the comment I deleted said) 😕 They did state correctly that Christmas isn't a holiday here for thaiz or thai govt workers so the office will be open the normal hours which is from 8:30am-4:30pm (closed from 12-1 for lunch).

To get a 30 day extension on a 60 day visa exempt entry in Bangkok you go to the immigration office at the IT Square Plaza Laksi location.
