A California man has been sentenced to more than three years in prison for running a business to help pregnant Chinese women travel to the United States to deliver babies who would automatically have American citizenship. U.S. authorities had sought a five-year prison term for Michael Wei Yueh Liu. Liu was convicted in September of conspiracy and money laundering for running a company known as USA Happy Baby. Birth tourism businesses have long operated in California and other states catering to couples not only from China but also Russia, Nigeria and elsewhere.
