why does it seems this topic is somewhat of a grey area?? i was advised one of the benefits of applying outbound was that there were no restrictions to travel. i have applied for her PR and her visa extension (which we still have received no acknowledgement as this is severely backed up) .... can someone shed a bit more light
The "no restrictions to travel" refers to the fact that you can leave Canada without abandoning the application. For those who apply inland, it's very strongly recommended they remain in the country for the entire processing of the application (i.e. without leaving for even one day). If the inland applicant leaves and is unable to re-enter Canada, their application is refused. This same restriction doesn't apply to outland.
The reason why this subject is a grey area is because whether your wife is allowed back in is at the discretion of the immigration officer. In your case there should be no problems returning. However there's always a chance.
Hope this helps.
