Overview

• President Trump’s January executive order seeks to deny birthright citizenship to children of unauthorized or temporary-status parents if the father lacks U.S. citizenship or a Green Card.
• Over 20 states have sued to block the order, and lower federal courts have issued nationwide injunctions preventing it from taking effect.
• On May 15, the Supreme Court heard arguments on whether such injunctions should apply nationwide or only to the parties involved in the lawsuits.
• Liberal justices expressed strong reservations about the Trump administration’s arguments, while conservative justices showed openness but raised practical concerns.
• If nationwide injunctions are narrowed, citizenship rules could vary by state, potentially leaving children born in the same hospital with different statuses.
