This case is incredibly rare so it is very difficult to predict how IRCC will assess any potential issues. The citizen has never lived in Canada and acquired citizenship through their parent in middle age and went on to sponsor their family soon after. Typically in cases the Canadian citizen has lived in Canada at some point in their lives and often a large part of their lives. Maybe it is because this family are US citizens but given the Canadian citizen have never lived in Canada and only recently obtained their citizenship typically the family would need to provide significant proof of plans to relocate to Canada to get approved for sponsorship. The VO may have been a bit too relaxed assuming they must have concrete plans to return to Canada if the mother applied for their Canadian passport at this point in her life and would only go through the time and expense of sponsoring their spouse and children if they planned on moving since otherwise it is extremely unlikely that they would be able to count time living with their mother in the US towards their RO.. Would add that I agree that being US citizens could make it easier to enter Canadian without being compliant with your RO versus other countries. Once your first PR card expires you will still run into issues in many provinces like not being able to secure a health card until you are able to meet your residency obligation and get a new PR card. If the family wants to move to Canada they should really do so in the next 5 years. If they apply for a new PR card IRCC will likely want to see that they are living permanently in Canada. In terms of needing concrete proof that they will be relocating to Canada I understand that things do come up but there won’t be any proof that there were plans to move to Canada after the short landing (for example next summer after the school year) since the family never had any plans to relocate. Sadly these cases are the reason others now have to provide multiple pieces of evidence in order to get approved for sponsorship.[/QUOTE]
