The top court has agreed to take on a significant case that puts to the test a historic principle: birthright citizenship for people 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 move was struck down by federal courts after constitutional questions were filed.
The Supreme Court's ultimate decision will either support citizenship rights for the children of immigrants who are in the US without authorization or on temporary visas, or it will end those rights entirely.
Next, the justices will set a time to hear oral arguments between the federal government and plaintiffs, which involve parents who are immigrants and their infants.
For more than 150 years, the Constitutional amendment has codified the principle that all individuals born in the United States is a citizen, with specific conditions for children born to foreign diplomats and members of foreign military forces.
"Every individual born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States."
The contested directive sought to refuse citizenship to the children of people who are either in the US without legal status or are in the country on non-permanent visas.
The United States belongs to a group of about a minority of states – primarily in the Americas – that grant immediate citizenship to any person born on their soil.
