In Mexico City, he wrote to María Antonia Figueroa, a teacher in Santiago de Cuba and the provincial treasurer of the 26th of July Movement in Oriente, to tell her about his successful tour of the United States to organize Cuban emigrants, and to request news of the economic section of the Movement in that province.

He wrote a letter to the Cuban emigrant Mario Villamía in New York, redirecting the letter he had sent to the executive of the 26th of July Patriotic Club in New York on 13 November, in which he complained about the poor work of that organization caused by rivalries, and asked them to make up for the time they had lost.
