From a 2017 Daily Beast report:
While Trump rails against U.S.-born children of undocumented immigrants, his Florida properties have become a playground for birth tourists from Russia’s upper crust.
The Daily Beast has discovered several companies are advertising rentals in Trump properties to expectant Russian parents. While the Trump Organization does not directly profit from subleases of privately owned condos, it does benefit from Russian patronage of the nearby Trump International Beach Resort.
Many of the companies that cater to Russian birth tourists advertise their services openly and warn no one will get in trouble as long as they don’t lie on immigration paperwork.
