As the Polish government, influenced by Josef Stalin, became more oppressive, his superiors began to view Miłosz as a threat: he was outspoken in his reports to Warsaw and met with people not approved by his superiors. Consequently, his superiors called him "an individual who ideologically is totally alien". Toward the end of 1950, when Janina was pregnant with their second child, Miłosz was recalled to Warsaw, where in December 1950 his passport was confiscated, ostensibly until it could be determined that he did not plan to defect. After intervention by Poland's foreign minister, Zygmunt Modzelewski, Miłosz's passport was returned. Realizing that he was in danger if he remained in Poland, Miłosz left for Paris in January 1951.
