Last week I got an email requesting to the sent passport with signed Annex A form and two photos for issuing PR confirmation. I already sent all the documents. But I forgot to sign the back of the photos which I realized later on. Does this slow down the process creates an issue? I emailed them on CPC-CTD-Ottawa@cic.gc.ca regarding same. Is there any other way to reach them from the USA? Any insights are appreciated. Thank you.
