It’s a cash flow revenue scam.

Catholic Charities is running a fundraising campaign to help finance the resettlement of the illegal aliens, WND reported. But the religious charities get the bulk of their funding not from private donors or church members putting checks into a basket. They get it from the federal government.
...The USCCB helps resettle not only unaccompanied alien children, or UACs, who enter the country illegally but also refugees fleeing persecution overseas who enter through legal channels.
The USCCB is one of nine agencies that receive hundreds of millions in tax dollars to resettle refugees and asylum seekers in the U.S. under contract with the federal government. Six of the nine contractors are religious groups, WND has learned, including the Lutheran Immigration and Refugee Service, Episcopal Migration Ministries, the Hebrew Immigrant Aid Society, the Church World Service and World Relief Corp., which includes a plethora of evangelical groups.
The Catholic Bishops alone received $65.9 million in federal grants to care for unaccompanied alien children and refugees, according to its 2012 annual report.
