Just like to wish all of you trying to get SS good luck. It seems like you will never get their at times, we had the same sort of problem but ours was after we got SS and then they pretty much just took everone of the cat 2 list and moved them to cat 3 back in September 2009. At the time we were told we would be waiting untill 2013 at the earliest. Then once again they changed their minds and we got our CO in Feb.
They are always changing their minds, hang in their and it will happen.
