Usually NDVO will not acknowledge by sending you any email/mail. They will update your file by having it on their internal notes. Ask for GCMS notes after 5-6 months.
Secondly, one can only assume that NDVO will process your application positively. Don't worry.
How, did you send the letter? Did you mention the application number? I hope you did.yes I emailed them first and sent u dated imm 5669 background check form, with my file number , UCI number
It was honestly a mistake from myself as I had one UK refusal which I already mentioned when I first submitted the application to CIC mississauga. I hope everything goes smooth and CIC don't take it as misrepresentation as it was never done intentionally by me as if I can disclose other country refusal I would never hide Canadian study visa refusal.
Thanx for your revert
