I just had a chance to get my NIC updated for one information. They asked me to get the printed information attested by designated 17 Grade officer. What's the need for that? They already have in their system all the verified information.
Also i notice several fields like Mother, Father Name their NIC was empty but the said information is present in their Database for sure.
In general why the heck govt offices ask for the attested document? what is the theory of attestation?
