In May–July 1924, he attended the 13th Congress of the Russian Communist Party (Bolsheviks) and the 5th World Congress of the Communist International in Moscow. At the same time, CPL organized its 4th Congress. He presented on difficulties faced by the party and outlined ways of increasing its membership. In early 1926, Požela together with Zigmas Angarietis prepared and published party position and action plan on the Seimas elections in May 1926. The program called for recruitment efforts of left-wing politicians (socialists, social-democrats). Požela was arrested imprisoned in Kaunas Prison in April–July 1926. Upon the release, he enrolled at the Faculty of Economics of Kaunas University. As CPL strengthened, it was decided to move its Politburo from Moscow to Kaunas. On 2 September 1926, Požela, Juozas Greifenbergeris, Faivušas Abramavičius, and others were elected to the Politburo.
