To be awarded the Philippine Liberation Medal, a service member must have met at least one of the following criteria:
- Participation in the initial landing operation of Leyte and adjoining islands from 17 October to 20 October 1944. An individual is considered to have participated in such operations if he landed on Leyte or adjoining islands, was on a ship in Philippine waters, or was a crewmember of an airplane, which flew over Philippine territory during the period.
- Participation in any engagement against hostile Japanese forces on Leyte and adjoining islands during the Philippine Liberation Campaign of 17 October 1944, to 2 September 1945.
- Participation in any engagement against hostile Japanese forces on islands other than those mentioned above during the Philippine Liberation Campaign of 17 October 1944, to 2 September 1945.
- Served in the Philippine Islands or on ships in Philippine waters for not less than 30 days during the period.
Personnel who are awarded the medal for participation in any of the above-mentioned operations are authorized a bronze 3⁄16" service star to the Philippine Liberation Medal for each additional qualifying action.
Members of the United States Armed Forces included the Philippine Commonwealth Army and Philippine Constabulary. Those members were also eligible to receive the Asiatic-Pacific Campaign Medal, often with a service star, for participation in the liberation of the Philippines.
