I received this email. It is primarily for Americans. However, I filled out 2 forms and returned. I asked for confirmation but have not received a reply. The Bank website does refer to these forms so I assume it is not bogus.
It's my understanding that foreigners cannot own property in Thailand; hence, the number of Thai wives/partners acting as owners/proxies. This whole affair reeks of bribery and corruption- the usual here. Feel sorry for the mid though.
I have received the email as well. I have another account with Krungthai Bank and am waiting to hear from them before proceeding. The forms themselves seem to be for US citizens
