Does your visa require it? If you are on DTV or other tourist visas then it's not required as part of the visa. If you have applied for a non O retirement visa then you will need a thai bank account as part of the extension

If you flew in on visa exempt then you will have been stamped in for 60 days not 30 so no need to do anything, just check your visa stamp.in your passport it should confirm 60days

@Will ********

just an arrival card, departure dates are optional

This is the access port for the TDAC

If you mean the TDAC then departure dates are not mandatory, no asterisk

@Simon ********

it's 180 days in a calender year so leaving and coming back will mean you exceed the tax number of days within the calender year!

I'm not sure i would get terribly excited about this, it's the same question they asked when the landing card was issued many years ago. I know when I fly out of Manchester I will use UK as my departure country even though I pass through Doha on my way to Bangkok. If you look at the TDAC for UK people there is also a separate Scotland option!!! So you can choose!!! Also they have choice of cities where you live back in the UK, the options here are all mixed up!! You have a choice of cities and counties!!! So the system isn't perfect so make a choice and enjoy thailand

You can only apply for a non O-A outside golf thailand, so you can apply while you are in Belgium. An O-A visa typically requires health insurance from an approved insurance company ( these are named on the e visa system ) like axa for example, you also need a police or criminal check and a health certificate. You will need the equivalent of 800k baht or 65kbaht monthly in a bank account but this can be your Belgium account does not need to be thai. Yes you can open account in thailand with a long term O-A visa. The first year of the O-A is multi entry with the option to get 2 years if you time your last entry. You don't need to inform anyone if you leave after 5 months or any other time
