The concept of birthright citizenship dates to English Common Law, and it was codified in 1868 by the ratification of the 14th Amendment to the U.S. Constitution, and was upheld in 1898 in a Supreme Court ruling called United States v. Wong Kim Ark, and it was further strengthened in 1940 when Congress passed the Nationality Act. President Trump signed an Executive Order that claim “The 14th Amendment has never been interpreted to extend citizenship universally to everyone born within the United States,” and says that only children born of at least one citizen parent will be a U.S. citizen. We get some clarity and context with two immigration attorneys, one with the ACLU and the other who has worked on immigration law for nearly 50 years.
