Earlier this year President Trump signed an executive order which seeks to restrict this right, which was established by the 14th Amendment in 1868.

President Donald Trump is fighting to end automatic citizenship for children born to parents who are in the country unlawfully or on temporary visas, part of his broader crackdown on immigration and a change that would overturn more than a century of court precedent.
