In that particular case i remembered reading on fb about this person that neither he or his wife tried to visit each other in 2-3 yrs not even after the birth of their child. The sponsor should have come after the child was big enough to travel or the PA should have tried to visit Canada since they hadnt met in 2/3 yrs. Or in case the PA was refused a trv, they should have visited another country to meet e.g. Dubai visa is easy to get.
Every case is different but sponsors should visit you atleast once a year because in most cases they dont require a visa to come back to Pakistan.
BTW Can u share the fb link for this group? I wonder what can one do if the appeal in court for sponsorship also gets dismissed. I spoke with one bro whose case was refused by ADVO. His ADR thingy was also unsuccessful. Any idea about it? Asking u bcz u read messages pretty frequently and hv more knowledge of the events here.
