Of the seven new security measures being proposed by the administration, four would be mandatory.
The mandatory measures include ( 1 ) an Electronic Travel Authorization requiring VWP travelers to register online in advance of travel; ( 2 ) more robust data-sharing efforts; ( 3 ) timely reporting of lost and stolen passports, whether blank or already issued; and ( 4 ) guarantees to repatriate nationals ordered removed from the United States.
The three additional measures focus on airport security standards, air marshals programs and common standards for travel documents.
