The nation's highest court has decided to consider lawsuit questioning citizenship by birth.

The top court has agreed to take on a significant case that puts to the test a historic guarantee: guaranteed citizenship for people born on American soil.

On day one in office this winter, the President signed an order aiming to terminate birthright citizenship, but the action was halted by lower courts after lawsuits were filed.

The Supreme Court's final judgment will ultimately affirm citizenship rights for the offspring of migrants who are in the US without authorization or on non-immigrant visas, or it will end them altogether.

Next, the court will schedule a date to hear the case between the administration and claimants, which comprise parents who are immigrants and their newborns.

A Constitutional Cornerstone

For nearly 160 years, the 14th Amendment has codified the doctrine that all individuals born in the country is a US citizen, with exceptions for children born to embassy personnel 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 disputed executive order sought to withhold citizenship to the offspring of people who are whether in the US without legal status or are in the country on short-term status.

The United States belongs to a group of about 30 countries – largely in the Western Hemisphere – that award instant citizenship to anyone born on their soil.
