the onus always lies with the individual and depends on how strict the immigration is, ie: Nonthaburi immigration say you don't have to report at all after leaving the country and coming back, Chiang Mai from what I have read are pretty strict on it.
Robert Lagas I think people are talking about a personal appearance at there own immigration office, not hotels as that is the hotels responsibility I believe?
For the original 90 day visa non0 the cash has to be in the bank for 30 days for the extension it has to be in the bank for 60 days, proof of the international transfer must be submitted with the application, ( at least that is what happened in my case)
I will be going for the non0 based on marriage soon and the same rules apply, only the amount is different as quoted by immigration in Khon Kaen
