In May 1951 Georgette travelled on the steamboat Reina del Pacífico from Paris to Lima. She was met as she stepped off the boat in Callao by, inter alia, Raúl Porras Barrenchea and Sebastián Salazar Bondy. She was taken on a tour of César Vallejo's birthplace, Santiago de Chuco. Georgette had brought with her Vallejo's manuscripts, along with some memorabilia; and she would live in Peru for the rest of her life. In 1957–1958, as a result of Raúl Porras Barrenchea's intervention, Georgette was granted a modest monthly allowance of 2,700 soles from the Ministry of Education. The understanding was that, as a result of this allowance, she would be able to publish Vallejo's remaining works – those which had not been published during his lifetime. The first major publication came in 1965, Vallejo's second travelogue based on his third visit to the Soviet Union; it was published in Lima with the title Rusia antes el segundo plan quinquenal (Rusia Facing the Second Five-year Plan) by the publisher Gráfica Labor.

Three years later, in 1968, Georgette published the most significant work, a facsimile edition of the typescripts of the posthumous poetry, now divided up as Poemas humanos (Human Poems) Poemas en prosa (Prose Poems) and España, aparta de mí este cáliz (Spain, Take this Cup from Me). Her pension from the Ministry of Education was unexpectedly curtailed, which led to a cooling of her relationship with the Peruvian authorities, and indeed with the academic community.
