I know people who have done this.
The report is accurate - middle-class or wealthy Chinese are paying $40K-$80K to visit these “birthing centers.” They are usually nice apartments, where they stay for a month after birth. These places may have a midwife. On thing NOT mentioned - if there any health issues whatsoever, the women are sent to PUBLIC hospitals, who treat them like any illegal alien without insurance. They then just skip-out on the charges.
So its not only an immigration scam, its often a welfare scam as well.
This bs was going on in the SF/Oakland area in the late 1960’s.
