US Supreme Court has decided to consider case challenging birthright citizenship.

The US Supreme Court has will hear a significant case that puts to the test a century-old guarantee: automatic citizenship for individuals born on American soil.

On the inaugural day in office this January, the administration enacted a directive aiming to terminate the policy, but the move was halted by federal courts after legal challenges were initiated.

The Supreme Court's final judgment will ultimately support citizenship rights for the children of migrants who are in the US illegally or on short-term permits, or it will overturn those rights completely.

Next, the court will set a time to hear arguments between the administration and claimants, which involve parents who are immigrants and their newborns.

A Constitutional Cornerstone

For over a century and a half, the 14th Amendment has codified the doctrine that all individuals born in the United States is a US citizen, with certain exclusions for children born to foreign diplomats and members of invading forces.

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

The contested presidential order sought to deny citizenship to the offspring of people who are either in the US in violation of immigration law or are in the country on non-permanent visas.

The United States is among about three dozen nations – primarily in the Western Hemisphere – that grant automatic citizenship to all those born in their territory.
