"U.S. President Donald Trump said on Wednesday that his administration was seriously looking at ending the right of citizenship for U.S.-born children of noncitizens and people who immigrated to the United States illegally."
"The Republican president had told Axios news website in October 2018 that he would end "birthright citizenship" through an executive order. Experts have said such a move would run afoul of the U.S. Constitution."
Egregious abuses are seriously testing support for this policy in Canada. There's a lucrative business in wealthy Chinese women to fly to Vancouver when they're pregnant for the express purpose of giving birth in Canada to give their child a Canadian passport. After giving birth, they return to China, in this case leaving behind an unpaid hospital bill. In one Metro Vancouver hospital near the airport, 20% of all births are to non-resident (almost entirely Chinese) women.
