Today I have received a letter from UBS requesting a [Thai] TIN.
I was about to send them my PIN but got second thoughts. Since I have the so called LTR/WP visa, can I tell them that not of money transiting through UBS is assessable in Thailand and that therefore I have no TIN to provide?
I am not sure I want to do that, because I wouldn't like it if they closed my accounts. But their letter was threatening at all, a reminder might be though..
