I really don't know exactly how to check the CIC part of the PNP applications, as i am still waiting for nomination and don;t know the actual process of CIC part yet. But i have heard that when we submit application for PR to CIC office they give AOR (i don;t know what it looks like because i haven;t received yet

), in AOR there may be something like UCI (Unique Client Identifier number) which is used to check application status on CIC website
here.
I may be not accurate, you can ask the CIC applicants
here. They are in better position to give your answer accurately.
Hope for the best..
I know about cic as I am myself a pnp applicant but I wanted to know about SINP application tracker!!
