For some reason it won't let me fill out the timeline, it says the dates are too far apart but that's because I never formally received NOA2, it was sent by email a couple months after I was supposed to get it. I am indeed on a K1 visa. It expires on July 1st as I stated. But we are now married and I am submitting my AOS documents this week after seeing a civil surgeon for my i-693. How is it not a K1 visa just because it's expiring???
Thank you OldUser, everything you said was super helpful! I just wanted an ideas of whether it was possible or not to get to the funeral, but even if I can get the death certificate and go to support my family and sort out his estate as he has no will as his next of kin, that is fine with me as difficult as it will be not to attend.
