my case is almost identical to yours...
File transfer Jan 2011...
Full wedding + visited my husband for 4 months in afghanistan. Celebrated our birthdays and other family weddings...all proof was sent including visas/pictures.
Only have gotten re-med in November 2011..and since then nothing - its been 6 months. I emailed through my husband's account about PPR and they said the first in Feb that background checks are underway and now I emailed them a week ago but no reply. I contacted my MP again and she said she has sent an email inquiry as well and when she gets an answer she will let me know. I am going back to afghanistan in a few weeks..haven't seen my husband for a year..hopefully we will have some answers before I go. Unfortunately I cant stay again for 4 months..management at work has changed so I only managed to get 1 month off..
Seems like CHC has jumped over Jan 2011 cases and going to all the other cases except ours
