I am married to a Thai lady and also have a child here. I have read that for my 1st year I cannot use the monthly (40k ) method as UK does not issue confirmation of finances. But I have lived here now for few years using border bounces etc. if I can now show immigration 12monthly statements in Thai bank account of 40k + a month can i still not use this to obtain 90 day non O visa based on marriage or Thai child. Or do I still need to show 400k in Thai bank account to get the initial visa an 12 month extension?
