I would say the best people to answer this will be by calling the IRCC line.question guys. as my file is stuck at security clearance. so if i apply for security clearance myself through CBSA do you think it will have an impact on my citizenship security clearance as well? assuming CBSA will have a duplicate request (one from me and the other from IRCC). because i was checking the processing time on CBSA website and it is between 20 to 100 days. but my file is stuck for more then 4 months now.
