After travelling back to Romania in 1948, Șora became a member of Romanian Communist Party (PCR) and was employed by the Ministry of Foreign Affairs, at the time led by communist leader Ana Pauker. In interviews published after the fall of Communist Party rule in 1989, Șora claimed that he was unofficially "arrested". He was allegedly barred from holding a teaching appointment in communist Romania, but nevertheless became an influential editor for one of the main Romanian publishers, ESPLA. Șora's family emigrated to the West in the 1970s, and he was allowed to visit them in the 1980s. According to Aurelia Crăiuțu, he was allegedly forced to publish under pseudonyms rather than use his own name. However, Șora was still able to publish his third book in 1985.
