After two years in the US, Lissette and her sister were reunited with their parents in Miami and the whole family moved to Puerto Rico in 1965 where she lived until 1979 and where she worked as a singer. In 1977 she was selected by Univision, the biggest Spanish Language TV Channel of America to represent the United States in the sixth edition of the OTI Festival. Her entry, entitled "Si hay amor volverá" (If there is love, he will return) was warmly welcomed by the national juries, to the point that she ended second with eight points in a tie with the Dominican entrant Fernando Casado.
