Agreed, I am also in same situation. My kid's TRV was refused in march hence my husband has travelled and submitted PR application and I am back home with the baby.I agree....also for children born outside Canada, if we dont take them to Canada on TRV , mostly one parent stays back with kids till PPR & that parent if PR like me; has a residency obligation too to take care of...& another parent has to be physically present in Canada while sponsorship of children is ongoing....
