How to confirm if bgv is completed or not for Amazon

Need some help here

I have a joining in 15 days with Amazon.

In A to Z portal my bgv task is showing as Complete status.
But as i checked in Fadv portal it is showing 90% complete

What does this mean? Please suggest my bgv is completed or not?
If not how much time it usually takes for Fadv bgv to complete?
Also does Amazon bgv should complete before the joining date or it can stay in progress even after joining?

Please suggest
