I hate to admit to this, but we do live in a global society these days, and who ever gave us the rights or no rights to live anywhere on this planet ?
Tie, for example is a true bible believer. Were Adam and Eve restricted where they could live or not ?
Borders were established much later in the years to follow, by people and their governments.
Countries were formed, etc.
If it takes jobs away from others, because people move to somewhere better, so be it.
But it also creates growth in every aspect. (from agriculture , foods, housing, and all the goods they will purchase).
In the end it all works out.
It's not hard to figure that one out.
Look at China with billions of living there.
Now the richest country on earth !
For me it's hard to deny people seeking a better life and are willing to work hard.
It's 1 planet, and we all live and own it together.
