Households of only illegal immigrants will birth at least 6o0,000 children inside the United States during the next decade, according to the non-partisan Congressional Budget Office.

The revelation is included in a cost estimate for the Democrats’ DREAM Act Amnesty, which concludes that the full or partial amnesty of 2 million illegals will cost Americans roughly $25.9 billion by 2027.

The birth of children in the United States helps illegals stay in the country, earning the term “anchor babies.”

In fact, the CBO report notes that 900,000 U.S.-citizen children and youths already live in households with one or two illegal-immigrant parents who would be able to get amnesty under the Democrats’ DREAM Act. The CBO’s cost estimate for “S. 1615; Dream Act of 2017,” says:

CBO estimates that about 4.5 million U.S. citizens under the age of 18 have at least one inadmissible or deportable parent. CBO expects that about 900,000 of those [U.S.-citizen] children live in households with only inadmissible or deportable parents where one or both parents would receive LPR [green card] status under S. 1615. CBO also estimates that about 60,000 additional citizen children will be born to such parents in each of the next 10 years.

The 60,000-per-year rate would bring the number of children born in households of only illegal parents up to 1.5 million in 10 years.

The report argues that only half — 1.6 million of 3.25 million — of the potentially eligible illegals will get green cards within a decade if the DREAM Act becomes law, despite the massive legal and welfare benefits of being an American citizen compared to being an illegal immigrant facing repatriation to Mexico or Central America. The report says:

CBO expects that around 3.25 million aliens arrived in the U.S. before their 18th birthday and will have been continuously present for at least four years at the time of enactment. Not all of those people would apply for conditional LPR status nor would all applications be approved. Application rates for DACA and the legalization programs under the Immigration Control and Reform Act of 1986 (IRCA) were around 75 percent, according to immigration researchers. The approval rates for both programs were around 90 percent … On that basis, CBO estimates that nearly 2 million people would apply for and be granted conditional LPR status under S. 1615, most within the first five years after enactment. Others would apply for and receive that status in the latter half of the decade and even into the second decade after the bill’s enactment … Furthermore, CBO estimates that—of those nearly 2 million people—roughly 1.6 million would be granted unconditional LPR status during the 2018-2027 period; more people would receive that status after that 10-year period.

If more than half of the migrants win a green card in a decade, officials would have to raise the estimated number of children born to illegal immigrant parents who quickly benefit from the amnesty. The ten-year cost of the amnesty would also rise above $25.9 billion.

Each year, roughly 4 million children are born in the United States. The 60,000 children annually born to a household of one or two illegals is roughly 4 percent, or 1 in 25, of all U.S. children born each year.
