To acknowledge its chapters outside of the United States, the board of trustees took action in 1980 to change the name of the society to "Pi Gamma Mu, International Honor Society in Social Sciences". In 1982, the name of its official journal was also changed to International Social Science Review. In 1991 to enhance its international scope, the trustees approved the conferring of affiliate (or associate member) status on visiting fellows and exchange students who demonstrate academic excellence in their fields but are not otherwise expected to complete their degree programs at a Pi Gamma Mu sheltering college or university. The same international emphasis continued as the Philippines Alpha chapter commemorated its 75th Anniversary on March 7, 2007. The unique influence of the Philippines Alpha chapter is recorded in Scott Johnston's work, "Pi Gamma Mu International Honor Society in Social Science First 75 Years": “Again the quality of the people elected to the Philippines Alpha chapter has been most impressive. They have included two Presidents of the Republic, two Prime Ministers, a dozen Supreme Court Justices, and two dozen Cabinet members. Concerning the University of the Philippines itself, there have been six Presidents, a dozen Vice Chancellors and dozens upon dozens of Deans of the University.”
