US judge invalidates travel and visa ban on 39 countries: What happens next?

A US federal judge ruled that the Trump administration's immigration ban on 39 countries, imposed after a shooting in Washington DC last November, was unlawful. USCIS adopted policies targeting immigrants from those countries, creating legal uncertainty for countless individuals living in the United States. The ruling found that these policies violated immigration laws and administrative rules. The Department of Homeland Security has not yet commented on the decision, which allows the administration to appeal or request a stay of the verdict.
