What Is The Process Like For UK Citizens Receiving A Visa Waiver At Thai Airports?

And as there are multiple International airports in Thailand and the decision is made by the Immigration Officer who handles your passport and request to enter Thailand, there is not much more to tell.

You have experience enough to know the 3 most asked questions, but:

proof of funds in 20.000 Thb or equivalent currency in cash

proof of onward travel within 30 or maximum 60 days

proof of accommodation.

Good luck and you can always think to apply for a visa that fits your length of stay and the purpose of stay better than a 30 day visa free stamp for a 6 month stay. Good luck.

i not really understand your history, you mean you have been in Thailand from Oct 2018 until March 2019 or is it March 2019 until Oct 2019. In both ways it does not seem to be the same as your previous questions and pictures.

It depends on your history in their computer. No one here can say for sure if you will be hassled or not. Have your onward ticket , 20,000 baht and hotel reservations ready in case they ask for it.

you hand over your passport, the Immigration Officer makes a scan, looks at your history of entries and exits an visa or visa exempt entries used and decide to stamp a new 30 day Visa Exempt Entry, or decide to ask you some questions or denies you entry with a reason.

A visa exempt? It's ok. Or not ok. What's your visa history in Thailand?
