yea thats the problem with allowing anyone in right now with the quarantine period still at 15 days. its not worth it for short term visits. no one wants to spend 15 days in quarantine, even if its a month of vacation time. not worth it. as when you get home you probably have to quarantine again!
they are running the data collection period starting now, until jan 1'st i believe. so anyone arriving now will be subject to the 3 tests. and they will know by jan 15 what the decision is. i did read that the 10 day quarantine will only be for people from countries that have Covid under control, the USA is not one of those countries unfortunately
Will is saying to go to the immigration office to report and ask for an extension. no boarder crossing required. you could do this prior to covid. i think it costs 1900THB. but no one knows if this is still the case since they just announced they are allowing visa exempt countries to arrive for 30 days.
