The Supreme Court is currently reviewing a landmark case regarding the legality of birthright citizenship in the US, following a controversial executive order issued by Donald Trump.This policy seeks to deny automatic citizenship to children born on US soil unless at least one parent is a citizen or a lawful permanent resident, a move that directly challenges the 14th Amendment established in 1868.The administration argues that the phrase "subject to the jurisdiction thereof" excludes children of parents who may owe allegiance to other nations, potentially affecting approximately 255,000 children born annually.
