It so seems from roa_manoj's email that even though the application was received by CIO(NS) on 7th Apr, it actually was entered into their system on the 8th of April. I checked my status online and it is the same for me as well, i.e Application Recd at NS on 8th April (according to courier tracking) but in-system on 9th April.
I think this is important for the the applicants who wanted their applications to reach by the "10th April deadline" to avoid the IELTS. These applicants have to be extra careful about the IELTS. They probably have to write the test to be on the safe side if they are depending on the 67 pass point system.
I am not sure what were the reasons to make the "in system" entry of applications on the next day....maybe they collect all the applications on a said day and then enter them on the next day. This is the best explanation that I could think of.
Hope to hear good news soon for all of us.
