Guys who got the AOR they are in final lists to get the Nomination. In case you are missing any doc or details they will play ping/pong.
Otherwise there is no point to reject the other applications who submitted on 3rd date only.
They selected only initial 250 applications even though anyone rejected from that list no one will get an opportunity, means there is no buffer here.
In addition, they do not have stuff and not ready to bare the cost to hire officer for only 250 applicants. Furthermore, they know they have excellent website means automated tools or paperless based system
