I think you should call CGFNS and tell them that you have sent your visa screen app. form along with the photo id form. And explain to them that if they received the app. form, the id form should be with your app. form as well.
I had a problem too when I sent my application form and documents. I have waited for 10 days for CGFNS to send me an email or letter that they received my application but they did not so I called them up and explained to them exactly how I sent the application form and other documents. Then the lady told me that they did not receive anything from me but they will look for it. And to make the story short, if I haven,t called them up, maybe my application will not be processed until now and they will not do anything about it and I will still be waiting for their confirmation....thank you to silverdragon for advising me to call cgfns...and I did so they looked for it and finally processed everything.
So I suggest that you call them to save you some time and also for them to know that you have some concern regarding your application. Hope this helps...
