Security clearance staff are field staff and they Know Nothing about any other process of the selection.

They just send the clearance to the section. Which prepares medical letters for the final selected candidates.

They just know there part of clearance, if you have been on 2,3 different addresses like different permanent and residence address then 2 sections will be on your clearance, Final clearance is done when all sections send final clearance to the concerned section.

Best of luck
