NEW YORK CITY, New York — The Democrats’ draft Dream Act amnesty would likely add as many chain-migration foreigners to the United States population as are added by the total number of Americans who are born in four years’ time.

As House and Senate Republicans, Democrats, the big business lobby, the cheap labor industry, and the open borders lobby have teamed up to push an amnesty for potentially millions of illegal aliens who are enrolled and eligible for the President Obama-created Deferred Action for Childhood Arrivals (DACA) program, the impact the move would have on Americans would be likely unprecedented.

Under the current legal immigration system, immigrants who are given a pathway to U.S. citizenship are eventually allowed to bring extended family members, children, their parents, siblings, and extended family members to the country. This process, which makes up more than 70 percent of the current legal immigration, is what’s known as “chain migration.”

Research by the Migration Policy Institute (MPI) reveals that under a DACA amnesty deal, between about 800,000 and 3.5 million illegal aliens could be eligible for legalization to permanently remain in the U.S. Of those, MPI notes that 1.5 million of the estimated 3.5 million would be allowed to obtain U.S. citizenship.

According to Princeton University researchers Stacie Carr and Marta Tienda, newly naturalized Mexican immigrants in the U.S. bring an average of six foreign relatives with them. Therefore, should all 1.5 million amnestied illegal aliens bring six relatives each to the U.S., that would constitute a total chain migration of nine million new foreign nationals entering the U.S.

If the number of amnestied illegal aliens who gained a pathway to citizenship under an amnesty plan were to rise to the full 3.3 million, and if each brought in three to six foreign family members, the chain migration flow could range from 9.9 million to 19.8 million foreign nationals coming to the U.S.

This chain migration flow triggered by a DACA amnesty — where an end to chain migration is not coupled with the plan — would be more than double the number of babies born in the U.S. every single year, which stands at about four million a year. Should a DACA amnesty trigger a chain migration flow of 19 million foreign nationals, it would be more than quadruple the number of American births every year.

The chain migration of a DACA amnesty would potentially outpace the populations of American cities like New York City, Los Angeles, Chicago, and Houston.

Such a chain migration would boom the number of foreign-born residents in the U.S. to a historic high.

Currently, the foreign-born population is already at historic levels, reaching 44 million this year with no end in sight as legal immigration reductions to give relief to America’s working and middle-classes are stalled in Congress.

Trump has previously stated that an amnesty deal for DACA illegal aliens would have to include an end on chain migration in order to stop surges of legal immigration to the U.S., though it remains unclear how many Republicans would be willing to break from their big business donors to help pass a law to end chain migration.

Most recently, a group of Senators released legislation known as the SECURE Act that would end chain migration — thus reducing legal immigration to 500,000 admissions a year to give relief to Americans — but couples the pro-American immigration reform with an amnesty for DACA illegal aliens.

Nearly 120,000 foreign nationals have been allowed to enter the U.S. since 2005, despite coming from countries designated as state-sponsors of terrorism, including Iran, Syria and Sudan, Breitbart News reported.

In total, about 9.3 million foreign nationals have entered the U.S. since 2005 because of chain migration, making it the largest driver of legal immigration to the country.

As Breitbart News reported, chain migration makes up more than 70 percent of all legal immigration — with every two new immigrants bringing seven foreign relatives with them.
