Hey all, thanks for the reassurance. Sorry for my late response, I'd seen the messages but forgot to formally get back. I ended up moving her to my uncle's residence where we are currently residing in the basement. It's not ideal, but I'm thinking of buying a house with her and moving out next year, so it definitely won't be for too long. We updated her USCIS account to show she moved to my uncles address with me, around Sept/Oct 2024.
I did have another question though. When we submit the I-751, will we need to formally show records of us having lived together on a month by month basis? Or as long as we are living together by the time we file the I-751 it should be fine? Looking at the I-751, it seems like it asks all addresses the CR lived in... I ask because I don't really have any of those conversations with my manager recorded, so I can't really show USCIS that oh I was trying to move to SC so how are they going to believe me. So that's why I was like ok whatever, let's get her moved to the same address as me in NC after a max of 6 months, so we did that. I can try to explain it a bit. But as long as they don't ask for literal monthly records of us living together, I'm hoping it'll be ok.
Plus we are expecting a child next summer, so I'm hoping that would count for strong proof as well.
