Reuters news reports that President Trump is, once again, questioning the idea of birthright citizenship. They report:
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.
“We’re looking at that very seriously, birthright citizenship, where you have a baby on our land, you walk over the border, have a baby – congratulations, the baby is now a U.S. citizen. … It’s frankly ridiculous,” Trump told reporters outside the White House.
It isn’t the first time Trump has spoken about birthright citizenship. October 30, 2018, Axios, a U.S. online news organization, released an interview with President Donald Trump in which he explained that his team is working on an executive order to change the rules for citizenship in this country. An excerpt of the interview is above.
Legally, citizenship in the United States is granted to children born in the United States and U.S. territories. This is called Jus Soli, or the right of the soil in Latin. That right is rooted in the first section of the 14th Amendment to the United States Constitution which reads,
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

The legal right to birthright citizenship was affirmed by the U.S. Supreme Court in the case of The United States v. Wong Kim Ark in 1898. Wong Kim Ark was born in the U.S. and had traveled to China several times. In 1894, when he was returning from one of those visits, he was denied entry to the U.S. on the grounds that he was not a citizen. Ruling in his favor, Supreme Court Justice Gray explained, “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”

Since the Ark case, it has been understood that people born in the U.S. are citizens of the country. However, there are contrasting visions of citizenship around the world. Those include the idea of jus sanguinis or the right of blood. In practice, Jus Sanguinis often means that citizenship is determined not by your place of birth, but by the citizenship of your parents.
