Well CIC seems to have really meant that they would cancel incomplete applications. I just got a letter from CIC stating that they are canceling my application since I did not provide a FBI PCC which is not older than 6 months. Please note I did provide them with a PCC which was about 9 months old and also provided them a letter of explanation along with proof that I have requested for a new PCC in March. CIC seems to have lost it this time. I am obviously going to appeal against this through my lawyer but I wanted to post this so that everyone knows letter of explanations simply do not work. Just send your application only when its complete.
