Sir jee,
I have just applied for the AINP nomination and made alot of research on this process. They have recieved my application on 10th March and even I havent recieved any nomination or confirmation yet. As per their estimate, they will take 2 months to get back to you saying you have been accepted for nomination application(by email) and they take another 2 -3 months for generating a nomination certificate and mail it directly to CIC. I am in the same boat as you are for now. However, I think you should get a response from them before I would. Email me on
[email protected] and we can talk on phone if you feel comfortable.
