The Philippine visa waiver program is governed by Executive Order No. 408, signed on November 9, 1960 by President Carlos P. Garcia, and by subsequent executive issuances amending it. While visas are issued by the BI, the program itself is administered by the Department of Foreign Affairs, which maintains a list of countries eligible to participate in the program. In principle, nationals of countries which maintain diplomatic relations with the Philippines and whose nationals are not classified as restricted nationals by the DFA are allowed to enter the Philippines without a visa. Eligible nationals availing of visa-free entry must possess passports valid for at least six months beyond their contemplated period of stay.
