my beautiful (ok even though I do believe this I am allowed to go for brownie points aren't i?) wife had her medicals done in August 2012 in Kenya. We sent our application package in early november and one day after I was approved as sponsor it was noted on the CICsite that her medicals had been received. we were told in August that the medicals would be sent from Nairobi to London and then from London to Mississauga where they would be held until our application package arrived. oh and of course we had to include a copy of the receipt from the medicals with the application package.
everything seemed to happen exactly as they said.
as for the passport pages, we chose to send copies of those in to verify travel and living as we had indicated on some of the forms. ie: copies of visa entry/exit stamps which matched security clearances for places lived 6+ months.
