you should learn to read!! He was not asking for the amount for retirement. He was asking for the minimum deposit for opening a bank account which is a couple of hundred baht. TRY to read the post again - maybe you get it right the 2nd time.
well the extension of the stay permit is dependent on the reason. If married we must show marriage certificate and 400k etc. Jack said the non o is a retirement visa - there is the marriage variation too.
well that information is wrong. Not the 1st time embassies have wrong or outdated info. Seen that from the Thai embassy in Denmark. If you are curious you can check Thai immigration official web site and see what they say about the non o. You will of course find the correct info there.
they are very nice in Udon 😊. For example last year for my extension they were not satisfied with some of the photos - they said just send new ones to us from the Line app 😊
