Via this comes this article subtitled "Scripture provides more than easy slogans and soft platitudes about welcoming foreigners." It ends with this:

Every Maria [subject of a PIIPP in a Christianity Today editorial] who gains a "better life" hurts our Patricias [low-wage U.S. citizen from an L.A. Times Magazine article], who have no where else to turn but to the civil government under whom God's providential hand has placed Patricia for protection. Rationalizing immigration policies based on a warm, soft, anecdotal, "feel-good" approach to legislating fails to do justice to fellow Americans. We deserve policies based on the factual, reasoned approach to legislating that places law and order right under biblical principles.

If you get a chance, send it to people like Cardinal Roger Mahony.
