My quesries are:
1. Should i apply now for passport renewal or after MR?
Yes you should, because immigrant visa expiry is 1 year from medical or passport expiry date, whatever comes first.2. Do i need to inform CIC / VO or to both?
No, when you are asked for passport copy, then submit renewed one.3. If i do need to inform both, form of communication should be post / email / both?
You dont need to4. Will require addresses (postal/email/both) too pls? if i do need to inform them
No need to inform them, wait for their instructions.
I am just curious, how do you exactly know your expected medical request date 11/01/2015 ?
