A right-wing author, Peter Schweizer, alleges China exploits US birthright citizenship laws to create a "Manchurian Generation." According to his investigation with the Government Accountability Institute, soon-to-be Chinese mothers travel to the US to give birth. Their children receive US citizenship and then return to China to be raised under Communist Party control. Later, these children come back to the US as adults with full legal rights. Schweizer writes, "China is not simply competing with America economically." He warns Beijing is "weaponizing US birthright citizenship rules" as a "time bomb". The book titled The Invisible Coup says birth tourism has surged over 15 years. It estimates 750,000 to 1.5 million Chinese nationals gained US citizenship by birth. Many parents travel only to get birth certificates and raise their children in China. Once grown up, these individuals can vote, work in government jobs, and sponsor relatives for US residency. “These ‘Americans’ have never lived in the US and are being raised in China under the strict indoctrination of Chinese Communist Party-controlled schools,” the report says. Schweizer suggests this impact may be felt by 2030. The investigation also exposes a bigger scheme involving American surrogate mothers who carry children tied to senior Chinese Communist Party officials. One case cites Guojun Xuan, a 65-year-old Chinese businessman and CCP official, owning over $100 million in California property. Schweizer claims Xuan ran a “surrogacy command center” from his $4.1 million Arcadia mansion. Officials found 15 children there in May 2025 linked to a multi-state embryo network. The book says 107 surrogacy companies in California are owned by Chinese people connected to elites including intelligence and military figures. The US State Department has warned that birth tourism poses a "potential long-term vulnerability for national security," letting foreign nationals skip normal naturalisation processes.
