He was one of the founders of the Galeguista Party in 1931 and worked for the approval of the Statute of Autonomy. He was elected congressman in the 1936 elections. When the Spanish Civil War began, he was in Madrid as part of the commission that submitted the Statute to Congress, and this saved him from being assassinated by the fascist forces as it happened to many of his comrades in Galicia. Together with Castelao, he founded Solidaridad Galega Antifeixista in Valencia. In Barcelona he was the legal attaché of the Commissioner of Defense, the also Galician Bibiano Fernández Osorio-Tafall.
At the end of the Civil War, he crossed the French border and he embarked with Marcial Fernández on the ship Queen Mary to New York, where they arrived on March 29, 1939. There he met again with Castelao, Basilio Alvarez, Emilio Gonzalez López and Ernesto Guerra da Cal. He was invited by Ramón Mosteiro to speak with Marcial Fernández in favor of the activities of the Frente Popular Antifascista Gallego, in New York and throughout the United States. The young Galician José Lores (from Lérez) was their driver. The aim of this tour was to raise funds to charter the steamboat Ipanema, that brought Republican refugees from Francia to Mexico.
Suárez Picallo left North America in July 1939 for for the Dominican Republic, from where he left for Chile because of the Trujillo dictatorship, and finally to Buenos Aires. In the Latin American exile, he participated in the creation of GALEUZCA in Chile and the Consello de Galicia in Montevideo (Source: Lois Pérez Leira, Ramón Suárez Picallo, o primeiro deputado da emigración; Miguel Anxo Seixas Seoane, Castelao.
