I submitted my application in January, 2017 after I received ITA. However, at that time, I did not have FBI clearance, so I mentioned that in the Letter of Explanation.
I just received the FBI clearance now. How can I attached the additional document, so that it can be checked with my current application?
If I wait for them to ask me, there may be too much back and forth, and reopening the file may take another few months. Since I have all required documents, I want to make sure CIC reads the complete application.
CIC generally sends you an E-mail stating the documents which need to be submitted. With that E-mail an additional field is opened in your account where you can upload documents.
You can also add documents to your submitted applications using a CSE. it usually takes 10 days .
