She was detained on November 2, along with Carmen María Pérez Roque and Ruth Mary Reynolds (The American/Puerto Rican Nationalist) and held in the La Princesa jail. During her trial in the federal court in Old San Juan, she was uncooperative with the U.S. government prosecution and refused to recognize the authority of the U.S. over Puerto Rico.

Later years After her release from prison, Viscal went to Cuba, where she was the Puerto Rican representative to the Cuban Parliament. As such, she met with Fidel Castro and Che Guevara. She was a devout Catholic, and thus became disillusioned with Castro's politics and selectively atheist policies. After publicly criticizing Castro, she escaped from Cuba with the help of her younger sister, Irma. Olga Viscal Garriga died in June 1995 in San Juan, Puerto Rico.
