Hi Awaisikhan,
I got the nomination from NB after reaching almost 7 months. I received a letter in my CIC Account inbox stating about NB nomination. After receiving CIC message only that I got the Nomination letter from NB to my Gmail. This nomination letter we will have to attach when we submit online application to CIC. Usually, nomination letter comes only 2-3 days after receiving the CIC message.
When you receive the nomination letter, read it carefully, go through the EE profile Nos., NOC Code spelling of your name etc. If any discrepancy found immediately send an email and also call their office and bring it to their attention.
In my case, the NOC code mentioned was wrong, I sent mail and there was no reply for 2 days, then I called them and they corrected it and updated in their system and emailed me.
Regards,
