Don't think there's any connection between 5 eyes and immigration. The Five Eyes refers to intelligence cooperation between the major English-speaking nations. That arose directly out of them having been allies in WW2 and facing a common adversary (the Soviet Bloc) in the cold war. In WW2, they didn't have as deep collaboration with many other Nato powers because France was occupied and Italy and Germany were the enemy they were fighting. It was natural for this close cooperation to continue from there.
