This exec­u­tive order explains that the fed­er­al gov­ern­ment will be more strin­gent while issu­ing all kinds of visas by estab­lish­ing “enhanced vet­ting and screen­ing across agen­cies.” This screen­ing would apply to both those who have yet to enter the U.S. as well as those already here. The gov­ern­ment will also iden­ti­fy nations that the U.S. believes have “defi­cient” vet­ting and screen­ing, poten­tial­ly bar­ring entry of peo­ple from those nations.
