This bill, known as the "One Nation, One Visa Policy Act," prohibits the Secretary of Homeland Security from admitting any national of the People's Republic of China, including those from Hong Kong and Macau, or individuals with PRC passports, without a valid visa . It explicitly forbids the use of Department of Homeland Security funds to allow PRC nationals to participate in any program authorizing admission without a valid visa. This specifically targets the Guam and Commonwealth of the Northern Mariana Islands Visa Waiver Program and its associated Economic Vitality & Security Travel Authorization Program. The legislation ensures that all individuals from the People's Republic of China, as defined to include Hong Kong and Macau, must obtain a visa for entry. Its primary purpose is to eliminate all forms of visa-free entry for these specified nationals into the United States.
