Hey. Gotta ask if this statement is law, or from experience.
There is a post on this board from someone claiming that she got her green card, no interview, and still lives with her abuser. Since, she didn't have an AOS interview, your statement would still stand. Obviously, this is just one case and I can't verify.
I did see a Youtube lawyer say there is specific language in the law that married/separated/divorced is not considered...but maybe that is for the 360 and not the 485?
