It will be fine, if they haven't asked you for extra documents yet you really have nothing else to do but wait unfortunately. Eligibility/BG check takes the most time for most people.
It should be enough, if you've already received PA's eligibility approval then all you have to do is wait for the rest of the process or wait until they ask for more documents.
No set timeline, I'm also waiting. A lot of the times delay comes after medical/bio are finished. Some people who submitted those for last year are also still waiting. :(
I've gotten ghost updates for the last 4 days, in another forum seems like people are getting it everyday too we're thinking it might just be system updates?
Yes, GCKey is where you'll receive your medical and biometric information. It's where you'll also receive any additional document request with regards to your application and submit the requested information if there's any.
I think they're just doing system updates, people from another thread got ghost updates on the same days and I did as well for those days but nothing is really happening.
