So this is what it says on my GCKey:Not trying to ruin your mood or bring you down but are you sure it says that your background check in progress on GCKEY?
Have you received prearrival email yet? Background check usually starts AFTER the Principal applicant's eligibility has been proved (usually receive a prearrival when that happens) - but in a few cases it has started before too.... What does it say about your eligibility on the Gckey (The 1s line, where it says review of eligibility)? And what does it say in the 3rd line (review of additional documents)? And what does it say about the interview (the 4th line)?
I am a January 18th 2018 applicant and I've got nothing yet after my file was sent to LVO.
On eCAS it will always show in process but that doesn't mean that your file is under going the process, as I have email them and they said it's waiting to be initially reviewed by an immigration officer at LVO. Which basically means that LVO has my file on the shelf since it's been sent to them.
