Once that he finished the Qestorat seminary school under Koto Hoxhi, he worked as a teacher in the villages of Kolonjë District, where he taught Albanian in disguise and prepared a number of friends as future teachers of Albanian. In 1887 Luarasi and fellow teacher Thanas Sina took over the running of the Albanian school in Korçë from Pandeli Sotiri after his departure. Between 1887-1893 Luarasi opened in Ersekë and in some villages of the Kolonjë District Albanian language schools. Luarasi's founding and promotion of Albanian schools in the Kolonjë area brought him into conflict with Philaretos, the Greek archbishop of Kastoria. In 1892 a circular letter was sent to the Kolonjë Orthodox Albanian population to dissuade ties between them and Luarasi with Philaretos referring to him as a "damned renegade" spreading "free masonry and Protestantism", while condemning his work with Albanian schooling and stating that the Albanian language "did not exist". Subsequently, he emigrated to the United States in the 1904 - 1908 period, where he was an active member of the Albanian National Movement and initiator of the patriotic associations Motherland Nostalgia and The Pellasgian. Luarasi also worked as a director and teacher of the first Albanian School of the Gjerazi sisters in Korçë and in 1909-1911 he worked as a director of the Negovani school, which had been founded by Papa Kristo Negovani. He also contributed to the organizations for the patg that lead to the Declaration of Independence of Albania from the Ottoman Empire. Petro Nini Luarasi was one of the delegates of the Monastir Congress that sanctioned the creation of the Albanian alphabet in 1908. For his patriotic deeds,secession of Albania from the Ottoman Empire, teaching of the Albanian language and social activism he was persecuted both by the Young Turks and the Ecumenical Patriarch of Constantinople. He died poisoned by them on 17 August 1911.
