Answer:
Surely, mass immigration is a violation of state sovereignty.
Step-by-step explanation:
State sovereignty is defined as a concept in which the state or the region are in total control of people and the property within their own territory.
So according to the question, if the people living around or sovereignty state are all migrated than there would obviously cause chaos.
There would be no one to run the state or there would not be any sort of activity going on.
