About 72,000 United States-born children delivered every year to foreign tourists, foreign visa workers, and foreign students are rewarded birthright American citizenship, a new study reveals.

Research by the Center for Immigration Studies finds that every year, 39,000 anchor babies are born to foreign students and foreign visa workers, as well as 33,000 anchor babies born to foreign tourists every year.

This indicates that about 72,000 anchor babies are born to foreigners who are legally temporarily in the U.S. These U.S.-born children — in addition to the 300,000 anchor babies born to illegal aliens every year — are immediately rewarded American citizenship simply because their foreign parents delivered them in the parameters of the nation’s borders.

To date, the U.S. Supreme Court has never explicitly ruled that the U.S.-born children of illegal aliens must be granted automatic American citizenship, and a number of legal scholars dispute the idea.

Many leading conservative scholars argue the Citizenship Clause of the 14th Amendment does not provide mandatory birthright citizenship to the U.S.-born children of illegal aliens or noncitizens, as these children are not subject to U.S. jurisdiction as that language was understood when the 14th Amendment was ratified.

For a year, President Trump has signaled that he has reviewed signing an executive order to end birthright citizenship, otherwise known as the “anchor baby policy,” as the U.S.-born children of illegal aliens are often referred to as “anchor babies.”

Today, there are at least 4.5 million anchor babies in the U.S., exceeding the annual roughly four million American babies born every year and costing American taxpayers about $2.4 billion every year to subsidize hospital costs. Every year, about 300,000 anchor babies are born in the country, and as of June, there has been an average of about 124,000 anchor babies born this year.

The sanctuary state of California is home to at least 1.2 million anchor babies under the age of 18, as Breitbart News reported. This is roughly twice the total population of Wyoming. The total of anchor babies under the age of 18 in ten U.S. states is more than four times the population of Boston, Massachusetts.

In total, there are now an unprecedented 62 million immigrants and their U.S.-born children living across the country, as Breitbart News has previously reported. As of 2017, there were 17.1 million U.S.-born minor children of immigrants in the country.
