"In short, the Old Testament teaches fair treatment of resident foreigners, with certain requirements of the aliens related to religious and civil legal standards. It also instructs that aliens were to assimilate to the Hebrew culture. Boundaries are meaningful, as well, and foreign presence among the Hebrews on several occasions was a curse. Few details of immigration procedures, standards, or other policy prescriptions appear. To infer some open-borders or mass-amnesty mandate from what actually appears in Scripture is wrong."
