President Donald Trump said in an interview published Tuesday that he plans to sign an executive order to end birthright citizenship in the U.S., which would mean children born on U.S. soil to illegal immigrants would not receive citizenship as they do now.

“We’re the only country in the world where a person comes in, has a baby, and the baby is essentially a citizen of the United States for 85 years with all of those benefits,” Trump told Axios on HBO. “It’s ridiculous. It’s ridiculous. And it has to end.”

Trump is wrong to suggest the U.S. is the only country that offers birthright citizenship, considering 33 nations maintain the practice, which is known as jus soli, or “by the soil”. However, he would be right to suggest that the U.S. is an anomaly in the sense that it grants citizenship to more immigrants and has less restrictions on birthright citizenship than other countries.

Trump told Axios on HBO that his administration is “in the process” of changing birthright citizenship laws “with an executive order.”
