- Does not being on a temporary work visas in USA constitute reason enough that we will move to Canada upon approval of PR there ?
It is possible that would be taken into account. Then again, maybe you feel that your job is secure and would prefer to stay on a temporary work visa but taking PR as a back up plan in case the economy in the US gets even worse.
- Does the application for PR allow scope for proving at a later date in the process that we will move there. i.e. We apply and if asked by authorities of our intention of moving there, we would begin our apartment rental/buy process and submit such documents as an addition to the application. I ask, because without any knowledge of when PR can/would be approved, how would we go about securing a rental apaprtment?
If you don't give sufficient proof that you are planning to come and live in Canada, they will reject your application. I suppose you have appeal rights with this application like a general outland application but you would have to spend time to wait for your appeal so you can add some data if you didn't have enough. Some people have found it hard to prove intent to live in Canada enough to get accepted in which case your wife would have no choice but to move to Canada first and apply from there.
