i have this question....if me and my wife (italians over 50 years old) come in Thailand with Non Immigrant O visa 3 months validity... what documents do we need (before the visa expires) to obtain the annual visa extension? moreover every year for the annual renewal are the required documents always the same? Is 800,000 Thb in total enough on a bank account in the name of both or must it be two current accounts with 800k thb on each current account?

thank you in advance for your help
