Since 2016, those who have previously traveled to Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria or Yemen on or after March 1, 2011, or who are dual nationals of Iran, Iraq, North Korea, Sudan or Syria, are not eligible to travel under the VWP.[14] However, those who traveled to such countries as diplomats, military, journalists, humanitarian workers or legitimate businessmen may have this ineligibility waived by the Secretary of Homeland Security.[15] In any case, those ineligible for the VWP may still apply for a regular visa from a U.S. embassy or consulate.
