Get a letter from bank in SG proving deposit of minimum THB800k equivalent. The amount can be in SGD, subject to exchange rates used by the Thai Embassy for calculation of equivalent amount. Refer to Thai Embassy in SG for list of required documents.
Will the Bank send notifications to submit proofs of meeting criteria or do we have to approach the Bank on our own initiative to submit relevant documents?
I am talking about 1 year retirement visa straight from home country thail embassy. Not 90 days plus application for 1 year in thailand. Unless I misread your reply. I am just trying to help and not to show off, so there's really no need for you to imply that I am giving unnecessary information. You could have just ignored my comment.
I managed to apply for 1 year retirement visa through Thai embassy in Singapore with proof of THB 800k equivalent in my bank account in Singapore. I am a Singapore citizen. So you may to call Thai embassy in your country to check whether they will process your visa with THB800k equivalent in your home country.
