JMZ: LOL, it looks like your application is almost done compared to mine.
Since your background check is in process the you must hear something soon. (When did your background check status changed from "Not Started" to "In Process" ?
For me, check the below, I don't even have something written next to "Review of submitted documents" , at least for you it is written "provided"
+ my background check is not started :
Application/profile status Open
Review of eligibility Review in Progress
Review of medical results Passed
Review of submitted documents
Scheduling an interview Not needed at this time
A background check is needed Not Started
Final decision Not Started
