Including those photos, bills, leases etc.? They scan those documents and store them digitally?
The CIC agent today told me, that they do NOT necessarily forward all parts of your application to the receiving VO. (They might, but they might not).
The protocol, he explained was to forward information pertaining to the PA. So, PAs documents, info, ID, family info etc. He said obviously all required forms and government certificates go to the VO.
We got talking about this because I asked if I qualify for "urgent processing" since I am due to have baby in May. He said, no, but that to ensure VO has all details about my situation, maybe I might want to forward my medical situation with my reference letter and MP's letter to the VO to ensure they 'have the full picture'. He said it is no guarantee that doing so would influence anything and applications still process in order, on case by case basis.
The agent informed me if there are mitigating circumstances for the sponsor, let's say Sponsor has a job offer or in my case, pregnancy, it does not hurt to send the VO a copy of that medical info. When assigned to Mexico VO, I "may" want to pop them an email with my application # + UCI and include my letter/ reference letters of utmost importance (like from my MP), doctor's letter or (sponsor's) medical results - baby's due date. He said this can or cannot have an affect and the reason being is those things aren't always forwarded on.
It is no guarantee that supporting items other than essential info for the PA are sent along with your file to the VO.
The CIC agent on the phone today said Canada does hold some of the info that they use in the initial process. He did say: "Documents used to determine eligibility of the sponsor like bank and work info, photocopied pages of sponsor passport, work history, my bills, sponsor ID, lease agreement, bank info, etc, is a good chunk of it that does not need to get forwarded on", since sponsor eligibility is determined.
If some 'frivolous piece' of the application outside of official documentation or relation to the PA may be of importance in the case from the sponsor's side, by all means drop a line to the VO referencing your case. I thought this was a really interesting piece of advice. It is not a guarantee to say the initial office forwards things like reference letters, job offers or sponsor's pregnancy results to the VO.
