US Supreme Court agrees to consider case questioning birthright citizenship.

The top court has agreed to take on a significant case that questions a century-old guarantee: guaranteed citizenship for those born within US borders.

On the inaugural day in office this winter, President Donald Trump enacted a directive aiming to halt the policy, but the move was halted by the judiciary after constitutional questions were filed.

The Supreme Court's ultimate judgment will either support citizenship rights for the offspring of migrants who are in the US undocumented or on temporary visas, or it will nullify the provision completely.

Next, the judges will set a time to hear arguments between the government and the suing parties, which involve immigrant parents and their infants.

For more than 150 years, the Constitutional amendment has codified the rule that every person born in the country is a US citizen, with specific conditions for children born to foreign diplomats and personnel of foreign military 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 refuse citizenship to the offspring of people who are whether in the US in violation of immigration law or are in the country on short-term status.

The United States belongs to a group of about a minority of states – primarily in the Western Hemisphere – that grant immediate citizenship to anyone born within their borders.
