If you are still trying to work out when you'll be interviewed then it sounds like you arent scheduled yet - so go ahead and have KCC unlock your DS-260, make the changes and resubmit. Unless you are about to be scheduled this month, you should be ok.Damn it! Yep, when I entered I was still living in Australia. I put in the ds260 back in June, and have just submitted the additional documentation now. Just trying to work out when-ish I’ll be interviewing / potentially moving!
To help identify where you might be in the process, whats your CN?
