In this press release, the Department of Homeland Security (DHS) reminded travelers from 27 Visa Waiver Program (VWP) countries that as of June 26, 2005, they must have a machine-readable passport to enter the United States without a visa, as mandated by Congress. Machine-readable passports have a sequence of lines that can be swiped by U.S. Customs and Border Protection (CBP) officers to confirm the passport holder's identity quickly and to obtain other information about the holder typically found on a passport's inside cover.
