 With respect to all references to "country" or "countries" in this document, it should be noted that the Taiwan Relations Act of 1979, Pub. L. No. 96-8, Section 4(b)(1), provides that "[w]henever the laws of the United States refer or relate to foreign countries, nations, states, governments, or similar entities, such terms shall include and such laws shall apply with respect to Taiwan." 22 U.S.C. § 3303(b)(1). Accordingly, all references to "country" or "countries" in the Visa Waiver Program authorizing legislation, Section 217 of the Immigration and Nationality Act, 8 U.S.C. 1187, are read to include Taiwan. This is consistent with the United States one-China policy, under which the United States has maintained unofficial relations with Taiwan since 1979.
