US Supreme Court has decided to consider lawsuit questioning citizenship by birth.

The US Supreme Court has will hear a landmark case that challenges a longstanding constitutional right: guaranteed citizenship for individuals born within US borders.

On the inaugural day in office this winter, President Donald Trump enacted a directive aiming to terminate birthright citizenship, but the order was subsequently blocked by federal courts after legal challenges were brought forward.

The Supreme Court's eventual judgment will ultimately support citizenship rights for the offspring of foreign nationals who are in the US without authorization or on temporary visas, or it will end them altogether.

Next, the court will set a time to hear oral arguments between the federal government and plaintiffs, which comprise foreign-born parents and their infants.

The Legal Foundation

For over a century and a half, the Fourteenth Amendment has codified the doctrine that anyone born in the United States is a citizen, with exceptions for children born to embassy personnel and members of occupying armies.

"Every individual born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States."

The contested executive order sought to withhold citizenship to the children of people who are whether in the US illegally or are in the country on temporary visas.

The United States is among about 30 countries – primarily in the Western Hemisphere – that award automatic citizenship to anyone born in their territory.
