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.
