it’s not an impression. Thai immigration has seen bad patterns from tourist . Especially UK and Israel check into a local hostel and you will see how they behave. Literally want to smoke , and play pool all day, and don’t want to support local businesses.
They want to make sure you have the proper visa if you are planning on staying for more than 6 months. Even if you have a multiple entry visa it’s up to the discretion of the immigration officer if he lets you in or not.
Did you even submit all the paperwork correctly??! They can’t approve your DTV in any country if you don’t satisfy the requirements. I mean 😪 just because you Applied in China doesn’t mean you will get approved in China.
