Sorry if this has been asked before. I have searched and read posts however, can’t really find an answer. I currently have an O-A visa based on retirement, the visa expires in January although I have been stamped in until October 2020. I am returning to the UK in January. If I forfeit my 'free' second year, can I replace my O-A with a 12 month METV non-immigrant O visa from London. Many thanks
