Under the order released on Friday, travellers from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen may not enter the country for at least 90 days while Kelly and others determine whether there is enough information available to screen them.
“Some of those countries that are currently on the list may not be taken off the list anytime soon, if they are countries that are in various states of collapse, as an example,” Kelly told a press conference.
Kelly said others may be added if it is determined they “could tighten up their procedures” to ensure more secure vetting, Reuters reported.
