The court lifted the lower courts' injunctions and allowed the order's travel ban to go into effect "against foreign nationals overseas who have no connection to the United States at all".
Trump's original order barred entry from all citizens of those countries and also established a 120-day moratorium in the United State's refugee resettlement program.
