background check is done by cbsa not by cic
cic sends your file to cbsa once its done cbsa sends it back to cic.
once cic rec your file they issue the visa. I did some research cbsa can take from 9-18 month to clear each case for pr visa
and 10 to 20 days for trv visa (vistor). the embassy in beirut requested comprehensive security for my wife as per cbsa notes.
security check is done for both applicant and sponcer even im a canadian cit for more then 18 years they embassy requested security for both of us.
my wife just completed 8 months of security i hope it doesnt take any longer this is very stressful
