you can’t get it ‘dissolved’. Just use it now you’ve got it. You got admitted on both entries, albeit with a bit of scrutiny, so it’s still viable for you to use it.
A similar level of disinterest when entering the country as well.
The worst thing that happens if you don’t file a 90 day report is that when you want something done at an immigration office they notice you haven’t done one and fine you ฿2000
TM30 registers your location with immigration. When you need to report the fact you’ve been in the country for 90 consecutive days (90 day report) you use the immigration office that serves the location you registered with the TM30.
That’s the link between the two things.
I’ve used AirBnB places that do register TM30 and some that don’t.
I’ve also used licensed hotels that should, but don’t.
If you’re renting long term, one of the requirements on your checklist should be TM30 registration.
It should be done within 24 hours of your arrival in that property and the latest online method of registration that your landlord will probably use only allows access to the filing for a short period of time (7 days maybe?) so once your landlord has done it, get a copy asap, scan it, keep it, print it out when you need it.
So how, exactly, will this bank prevent people from sending you money?
I use my Bangkok Bank account all the time and when a group of friends go out, if we’re splitting the bill, sometimes I’ll pay it then my friends use my QR code to send me their contribution.
I don’t think the bank could stop that if they even wanted to, which they don’t.
