I've just renewed my retirement visa in Samut Prakan last week and I had the bank print out a years statement and update my book with a letter from the bank to state that I am who I am and that it's my account or something like that, the IMO checked every page of the statement ticking under every page to except the financial requirements.
I was told by Bangkok Bank that my card has to be renewed at no cost to me, so I went to my local branch in Bang Phli (Opened account in Hua Hin) to get the new card when I went to sign the document they said my signature was different from the one on the bank book, yes it was over 10 years ago. So they said I need to go to the original branch to do a new signature. I tried for about 10 minutes to do the old signature till I did one they were happy with.
I've just done my retirement visa today and went to Krungsri bank and got a year statement print out and letter for the immigration, nothing said to me about this subject
That's not what they told me, they said that Thailand only gets a 1 year international diving licence, I got one before I came out here 18 months ago but I think I left it in a hire car and that one from the UK was valued for 5 years.
