The reason you’re supposed to allow refuges to enter while their case is being decided is because of the “Voyage of the Dammed”, a ship full of Jews fleeing the holocaust that were denied entry in Cuba, the US, and Canada.
They were eventually allowed entry into England, France, and the Netherlands, the latter two of which were occupied by Germany shortly afterward.
