So unfortunately I got the update I was dreading the "your address was changed" one, so I was wondering if anyone who has gotten this update has also had their receipt numbers changed as well, I called USCIS this morning and the rep was also confused on why I had a WAC receipt number now, he told me to check the new ones from now on.
