You can have sovereign states with relatively free flowing immigration. And you can also have non-sovereign states with restricted immigration. And you can even have states with internally imposed restrictions to resettlement.

Ideally, I think most policy should be made at a lower level than the sovereign state in a democratic society. Administration from remote cities seems to create distrust. Best also to keep the army at a different level from the level that needs to respond most effectively to economic upset. This is the opposite direction than we have been trending in for the last several decades but I think it can change quickly.
