Hello! I saw in your earlier posts you said your receipt number starts with IOE. What does that mean? Isn't that an online electronic system? Does it still get processed at a center? You say you got Nebraska Service Center. I'm asking because today I found out the receipt number after chatting with Emma and it also starts with IOE. It was received and receipt notice was sent on 11/29 so still haven't received the mail. Did your notice contain access code to be able to add the case online? I tried to add ours to my own account I created for me first and later was able to add the K1 and AOS files, but this one I cannot. It says that it was already added to another account and I don't remember having another one. Did you experience the same thing? Is this normal for receipts starting with IOE? I did file citizenship online for me before and it started with IOE but honestly I don't remember the details. Thanks!
