The executive order suspends the entry of refugees into the United States for 120 days and directs officials to determine additional screening ”to ensure that those approved for refugee admission do not pose a threat to the security and welfare of the United States.”

The order also stops the admission of refugees from Syria indefinitely, and bars entry into the United States for 90 days from seven predominantly Muslim countries linked to concerns about terrorism. Those countries are Iraq, Syria, Iran, Sudan, Libya, Somalia and Yemen.
