If I may ask, had you not provided the IELTS test results to begin with? I have heard stories of people getting rejected because they have not uploaded their documents. But I have also heard people getting asked about additional documents. I guess I'm just trying to find a pattern here and see if not having all the documents uploaded in a perfect way would lead to rejection or documents request.
This is totally depend on luck and case officer,some time they directly the application for missing document, some time the request u to provide addition document, for additional document they will send u a message in your CIC account and provide space for upload the document
Also, may I ask how you got the document request? Email from your case officer maybe?
Thanks in advance for the reply!
