A significant industry has emerged of expectant mothers flying from China to states such as California or U.S. territories such as Saipan to give birth to American citizens, says investigative reporter Peter Schweizer.

As soon as the newborn is old enough to fly, mother and child travel back to China with their babies. Chinese state-run media began promoting such services years ago, Schweizer says.

“They are exploiting this on a massive scale,” Schweizer said. “It’s industrial, and we are completely oblivious to it.”

He estimates there are tens of thousands of such cases per year. When the child turns 21, their parents can then potentially claim green cards through them.

There are also growing anecdotes of surrogacy as another preferred route.

“Politically connected elites in China ... are hiring women in the United States to carry their children. They call them carriers. And these women are American citizens,” Schweizer says.

Schweizer is the author of multiple New York Times bestsellers, including most recently “The Invisible Coup: How American Elites and Foreign Powers Use Immigration as a Weapon.”

In this episode, he breaks down some of the incredible findings of his book.

Over the course of history, “migration has oftentimes been used as a weapon: a weapon of subversion, a weapon to overwhelm an enemy, a weapon to divide an enemy, a weapon to sow chaos,” he says.
