Another reason is those migrants temporarily revivify dying Conciliar parishes.

@angry bob, it is not that no one cares, however. I currently work in a building that is a mission church, medical and dental clinic, and source of other help. I have a friend who offers her excellent legal skill. I don't happen to agree that this is the "help" they need, and this VERY high % of the USCCB budget is shocking.

The more people from Latin America (most are Catholic) that come to the USA the more money the in the Church coffers. I don't believe they are worried about the peoples well being at all.
