It's gonna take a while. If you didn't hear anything then probably your application was properly filled. You will get file number as per timeline on website. Also now they will be able to meet timeline as well because it was H1B stream occupation list which qualified almost everybody to apply so there work load was getting higher. Now there is significant decline in application packet delivery at AINP office.
On the website it says the AINP Processing time is 11 months.. If that is the case and CIC does its work in time then it should be 18 months start to finish!! But, I dont think it will take 11 months for the entire processing!!
