Leviticus 19:33-34: And if a stranger sojourn with thee in your land, ye shall not vex him. But the stranger that dwelleth with you shall be unto you as one born among you, and thou shalt love him as thyself; for ye were strangers in the land of Egypt: I am the LORD your God.
I take that to mean the stranger should assimilate and become as you NOT live among you as a stranger.
Deuteronomy 27:17:
Cursed be he that removeth his neighbours landmark. And all the people shall say, Amen.
