From what I've heard, the notes are a totally different department. So changes are that the notes and PPR are just a coincidence. Congratulations btw, I'm from the states too and have been waiting since August.
I have not read all the posts in this thread so I apologize if it's been explained before, but why are you not surprised that it could be transferred? I am an American citizen with no criminal past and have never used social services.... And yet it has been over 9 months for me. I figured my app was pretty straight forward I literally spent months on it. I am terrified of being refused and thus separated even longer from my husband. If you ordered notes and that is how you weren't surprised, what did they say? My first set should be available in the next week hopefully.
