Jesus was an immigrant. He and his family left their homeland and crossed the border into Egypt in order to escape Herod's hit squad.
Had Jesus not escaped, He would have been one of the innocents who was murdered.
This means that immigration played an essential role in salvation history.
In fact, others in his ancestral line were immigrants who advanced salvation history. Think of Naomi and her family who moved to Moab, where her son married Ruth. Then the widowed Ruth, in turn, migrated to Bethlehem where she met Boaz and gave birth to Obed, the grandfather of King David, who fathered the royal line leading up to Jesus.
Without immigration there would have been no messiah and no salvation.
