IT IS THE SAME DOCUMENTS THAT WE SUBMIT IN CIO BUT THIS TIME THE ORIGINAL ONE OR NOTARIZED(certified true copy) BECAUSE THE VO OFFICE WILL CHECK IF THE DOCUMENTS THAT SENT IN CIO IS THE SAME DOCUMENTS AS YOUR ORIGINAL. IT'S MY OPINION.
But i feel as they have already asked for all the documents both from the CIO & VO list, now they are not going to ask for any other document except the RPRF and PCC(this one only from post 4/8 applicants who havn't submitted their PCC yet)
I guess the role of VO this time is just to do the background checks and check the authenticity of the documents.
Also in EG7, its nowhere mentioned to send another set of documents to VO, they simply mentioned to keep a photocopy of all the documents for our personal records.
Its my opinion..
