A Chinese woman has pled guilty to running a massive “birth tourism” scheme that saw Chinese children gain U.S. citizenship.

According to The Daily Caller:

A Chinese national has pleaded guilty to running a “birth tourism” business, which involved helping hundreds of pregnant clients enter the United States and give birth so their children would receive U.S. citizenship.

Dongyuan Li pleaded guilty to two federal criminal charges, one count of visa fraud and one count of conspiracy to commit immigration fraud, for her involvement in a birth tourism business that was based in Orange County, California, according to a press release from the Justice Department.

Per the plea agreement, Li admitted that she ran You Win USA Vacation Services Corp. between 2013 and March 2015. The company specialized in helping Chinese government officials and wealthy pregnant clients skirt U.S. immigration laws, allowing them to enter the U.S. and eventually give birth to children that automatically earned American citizenship.

The company, which operated out of Irvine and China, allegedly coached customers on how to make false statements to U.S. immigration officials and on their visa applications.

The woman’s customers were also coached on how to lie to the U.S. Consulate in China about how long they were planning to stay in the United States.
