Dear Garuna,
I agree with Dhana. Extra documents would only complicate things. The checklist clearly indicates what to include. Spouse educational certificates were required last year when claiming points under spouse education. But since, this year there is no provision of points for spouse education, so it would not be wise to include something that is not being asked. I do recall some few weeks ago, LVO asked a forum member to send certified copies of appointment letter as he had sent original letters. These conditions prevailed last year and cannot be implied this year as well. Most of the items the checklist clearly indicates "copies unless otherwise specified" . So if CIC has requested copies, the same should be followed and by sending original, it would not be an advantages but rather it delays the process as CIC will specifically look for what has been requested. In your case, i see that consultant has not thoroughly read all the instructions and followed checklist but rather he followed the last year check list. But for sure, i can say this will not be the case of rejection but delay only.
