you can put any flight arrival and departure date in that is on one of the flight co pany schedules. You don't need to book the flights just put down the flight numbers
you don't need a flight out if you apply for a non O retirement visa before you arrive. It's very simple to do especially when you are in your own home with time to fill it in. Your new life in thailand will start much easier having the non O sorted before you arrive
I don't understand why you would want the hassle of doing it last minute in the immigration line? I will take you 10mins to fill in before you arrive then easy when you land
visa exempt is as it says you are allowed to enter the country without any visa. It's not a visa at all that's why it's called visa exempt. This applies to a number of countries that get this visa exempt when the enter thailand which is currently for 60 days. A number of countries are only allowed to get a visa on arrival its not because they didn't apply for a visa in their home country, these are typically 15 days. They are not all tourist visas. One is visa exempt, one is visa on arrival but for only a few countries. A tourist visa is applied for through evisa before you arrive in thailand and is a visa, the tourist visa is again for 60 days.
i have read the thai law and for condos airbnb for stays greater than 30 days is legal as i said . Only stays less than 30 days is not. Your document just confirms what I said ?
airbnb is not illegal in thailand. It is legal if you stay for a month or more. It is illegal to have short term stays or compete with hotels which is deemed to be up to a months stay.
