thanks bro..my security check started on July 29, 2019 according to Ralph..should I wait for at least six months from that date before mailing LVO? because i have heard that it takes at least six months for completionBy emailing LVO at LDNIMMIGRATION@international.gc.ca , they will tell you 'Background checks are ongoing' - in the case security screening is going on and 'Your file is awaiting review by immigration officer' in the case the report has been sent by CBSA basically background checks will be completed and security will be passed by officer when he picks up the file.
