The U.S. Supreme Court is set to rule on a legal challenge to President Donald Trump’s order affecting birthright citizenship. The case centers on the constitutionality of the directive, which argues that children born in the United States to parents who are in the country illegally or only temporarily should not automatically be considered U.S. citizens at birth.

Multiple outlets report that the court’s decision will address whether the order is consistent with the U.S. Constitution’s citizenship provisions and longstanding interpretations of birthright citizenship. The challenge raises questions about how citizenship rules apply to children born on U.S. soil when a parent’s immigration status is unauthorized or temporary.

The sources do not indicate the likelihood of the outcome, but they agree that a ruling is imminent and will determine the future legal status of the birthright citizenship policy described in the order. The Supreme Court’s decision will therefore be closely watched for its potential effects on families and immigration-related legal standards.
