Arriving shortly in Thailand, using 60 day visa exemption.
Is there ANY hard and fast rule as to how early into that period you can apply for a 30 day extension??
The www is littered with contradictory opinions, ranging from "immediately after arrival" (albeit NOT at the airport) through to "a few days before the 60 days are up"... and almost everything else in between.
Is it simply a mess... at the discretion of the Officer in front of you... or is there a RULE?
