Fair enough,
@majesty It'd be so awful (and uncharacteristic, or am I being too kind?) of cic to expect documents they've specified they will explicitly request and delay processing due to their miscommunication. Sorry to hear this might have been the case with your application. 4 months delay :/ Can you post a copy of the parts of your GCMS notes that indicates this if you can? Thanks. If I end up getting GCMS notes later, then I can compare them to mine.
And I hear you on it being about specific VOs. I really hope that cic isn't going by stereotypes to decide which applicants are screened more thoroughly though and that it's on a case-by-case basis. Since you've clearly done a lot of digging into this, is there a thread where this pattern you've observed is being discussed? I ask so we can include the link when responding to questions so applicants from regions affected by this can make more informed decisions.
Anyway, I should get the request to submit the checks any day now (strangely, I've only got the med request as yet) so I will update in case I see delays in my background check further down the line.
