Foreigners brought more children to America from 2005 to 2015 than American parents delivered in any two years of the decade.

Extended-family immigration, known as “chain migration,” allows newly naturalized foreign-born citizens the right to send or bring foreign relatives to the U.S., including grandparents, cousins, aunts, uncles, adult siblings, and their children. In general, each new immigrant brings in three additional chain-migrants.

Since 2005, 9.3 million foreign nationals have been able to resettle in the U.S. for no other reason than they had extended family members already living in the country. This huge inflow outpaces two years of American births, which amount to roughly 4 million babies every year.

Even after discounting normal immigration, the number of chain-migration arrivals at the nation’s airports during five years exceeds the number of babies born during each year. In percentage terms, foreigners deliver one in five, or 20 percent, of all new arrivals at the nation’s airports or maternity wards every year.

The number of extended-family foreign nationals who have resettled in the U.S. in the last decade is greater than the total combined population of Los Angeles, Chicago, Dallas, San Francisco and Cleveland, the White House has noted in a new ad campaign that seeks to explain and end chain migration.

A decade of immigration to the United States where new immigrants can bring an unlimited number of foreign relatives with them has exceeded two years of all American births.

Extended-family immigration, known as “chain migration,” allows newly naturalized citizens to bring foreign relatives to the U.S., including grandparents, cousins, aunts, uncles, adult siblings and their children. Every year, roughly two new immigrants to the U.S. bring about seven foreign relatives with them.

Since 2005, 9.3 million foreign nationals have been able to resettle in the U.S. for no other reason than they had extended family members already living in the country. This total outpaces two years of American births, where every year roughly 4 million babies are born in the U.S.

As the White House has noted in a new ad campaign that seeks to end chain migration, the number of extended-family foreign nationals who have resettled in the U.S. in the last decade is more than the total population of Los Angeles, Chicago, Dallas, San Francisco and Cleveland combined.

The booming foreign-born population due to chain migration could be further exacerbated by a year-end plan by the Republican establishment and Democrats to give amnesty to nearly 800,000 illegal aliens shielded from deportation under the President Obama-created Deferred Action for Childhood Arrivals (DACA) program.

As Breitbart News reported, the chain migration impact of a DACA amnesty, whereby the newly naturalized immigrants can bring any number of foreign relatives to the U.S., has the potential to range from 9.9 million to 19 million foreign nationals.

Under this potential DACA chain migration flow, four years of American births would be outpaced by DACA-created legal immigration into the U.S.
