Thank you for the reply. I called CIC and it seemed like the agent were not sure about it too. I am thinking to write a letter of explaintion and upload it to the required doc column to let the officer know the background check is in progress, and he or she will receive it directly from the police force of my home county.As long as you are following requirements set by CIC in regards to the PCC provision you should be good. However, make sure you follow the steps to the smallest point, the most common refusal reasons seem to be the PCC.
If you feel concerned for whatever reason or unclear, call CIC and/or raise the CSE.
Quick question here: am I now IP (1)?
