Yes she moved from China to live in South Korea and became a citizen there when I met her. So we went through Seoul for her K1.
And yes, it's a complete mess and as I said, a deep rabbit hole. While I don't want anymore to do with whatever they are doing, I wanted to at least help them figure out what to do next as it seems she abandoned her own family. They still own a house there in Jeju, so I suppose they will just go there as they only have until December before their 6 months is up on their tourist visa.
