A friend of mine is a GC holder her Mom is almost 70 and is canadian..My friends Dad passed away and Her MOm has no family left and no one to take care of her..Will it be hard for her to be able to get her Mom into the US..Her Mom has her own income and will always have that money coming in she just wants to be able to take care of her Mom since her MOm is not able to do this for herself anymore..Any advice?
