@Tod ********
because the 800k are mentionned, I have it already on a Thai account and it was international transfer.
I've read before that I need a letter of the bank as well as the bankbook as a proof.
I've changed passport recently and I've read that if you change your passport you need a new bankbook to show to immigration.
So do I need a new bankbook before going to immigration where international transfer won't appear.
What the best way to proceed ? Bring old and new bankbook + bank letter to immigration
