You are not alone in this boat/ship there is long queue all waiting for further information from CIC. As you go through the spread sheets provided by ‘Rossie” for the application of 2014,15 & 16 you feel that there is no progress at all after Oct 2016 (when the Govt busy with Syrian refugee,), except few cases on 8&9 Feb and 8&9 March 2017 and then again pin drop silence. Don’t worry, be patient. Even there are so many, who’s medical and pcc validity already expired. It is the sole discretion of the Officer, he may extend the validity while requesting PPR as seen in some cases OR demand a fresh one.
