#touristvisa looking for some clarification on extending my 30 entry visa ,Recently visted the embassy in Pattaya to start the process was a little chaotic . This is my first time in thailand by the way. After being told we couldn't be in the building because i had shorts on and my girlfriend had a sleveless t shirt when we were directed in there to get our forms. The employee was doing there best but there had to be 100 people there some just as confused as i was. We decided to go buy some clothes so we could enter, we stopped at a private visa office and were told that if we applied for the extension that day the extension would start from the day we applied rather then the day it expires. But they could process it there. The price was double. My question. Do I need to wait to apply for an extension closer to the expiry date or can that be done at any time.

Thanks in advance
