Hi gents, I just wanted to update you in my visa and extensions transfer into my new uk passport, I went to Khon Kaen immigration yesterday, I took my old uk passport and my new uk passport I gave both to the IO and filled in the form she gave me ( there’s a link to it on this thread) she photocopied the page with my original non O visa and then she photocopied the pages with my subsequent extensions of that visa, she then stamped my new passport with the extensions, I know this is supposed to be free but she asked for 300 baht which I gave her, I did remark to her that the service is free and she replied it was to coverr photocopying . Anyway it all got done in around 20 minutes
