US Supreme Court has decided to consider legal challenge challenging birthright citizenship.

The nation's highest court has will hear a significant case that challenges a century-old principle: guaranteed citizenship for individuals born within US borders.

On his first day in office this January, the President enacted a directive aiming to terminate this practice, but the order was struck down by the judiciary after legal challenges were filed.

The Supreme Court's final decision will ultimately uphold citizenship rights for the children of migrants who are in the US undocumented or on short-term permits, or it will overturn the provision completely.

Next, the court will set a time to hear arguments between the administration and plaintiffs, which involve immigrant parents and their infants.

The 14th Amendment

For over a century and a half, the Constitutional amendment has codified the rule that anyone born in the United States is a American citizen, with certain exclusions for children born to foreign diplomats 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 challenged presidential order sought to refuse citizenship to the offspring of people who are either in the US illegally or are in the country on short-term status.

The United States is one of about 30 countries – mostly in the North and South America – that grant instant citizenship to anyone born within their borders.
