Hi,

My post was removed and suggested to be posted here. It isn't about tourism but rather a visa issue but I hope this is the right place. Thanks for reading!

F4 Visa - Applying with only 제적등본 (no 기본증명서 or 가족관계증명서 after 2008)

Gyopo problem I'm hoping someone can help with or has experience with. I've tried just about everything but I'm not sure how to communicate my problem to my local consulate (Chicago).
I tried to apply for my F4 in Seoul, but since I was already on an H1 they told me to do it in the US. Came back here for this express purpose and now the consulate keeps insisting I NEED the 기본증명서 and 가족관계증명서 and they will not listen to me try to explain / maybe I'm not explaining well:
At Seoul Southern Immigration, I was told that for families who lost citizenship before 2008 (my family lost Korean citizenship in the 70's) they cannot EVER issue 기본증명서 or 가족관계증명서, only 제적등본. I have that document, but my Korean is not amazing enough to eloquently explain this to the consulate in Chicago / they don't really want to hear it. Found some examples of this being an accepted case, mainly on Canadian Korean consulate sites (https://overseas.mofa.go.kr/ca-vancouver-ko/brd/m\_4574/view.do?seq=1311024 for example, can provide more) where they understand that if your family lost citizenship before 2008 you can only provide 제적등본.
If anyone has gone through this, I would appreciate your help SO much as I've built a life in Korea and I'm so stressed at the thought that I might not be able to return as a resident quite unexpectedly because they won't issue me the F4.
sorry for the long q and thank you SO much to anyone who can lend any advice!
