There is widespread consensus among Christian scholars and theologians that the Bible calls for compassion and hospitality towards immigrants.  

Leviticus 19:33–34 states: “When a foreigner resides among you in your land, do not mistreat them. The foreigner residing among you must be treated as your native-born.”

Deuteronomy 10:19 states: “You shall also love the stranger, for you were strangers in the land of Egypt.”

The quote from Deuteronomy referenced in this post actually comes from a section where Moses warns about the consequences of not adhering to the commands of God; it is not a warning against immigration. 

Deuteronomy and other parts of the Bible explicitly command followers to protect and love immigrants.
