While in the USSR she traveled throughout the huge nation, including the Ukraine, Kuznetsk, Stalingrad, Kiev, Siberia, Central Asia, Uzbekistan, and many more. She also traveled into Poland, Germany, and Britain. While in the Soviet Union, Strong met with Joseph Stalin, Vyacheslav Molotov, and many other Soviet officials. She also interviewed farmers, pedestrians, and factory workers. She wrote articles for newspapers and magazines, along with pamphlets as well, gaining "many friends and to become very popular throughout the world." At the same time, she created "suspicion regarding her political loyalties" among the Soviets and the FBI who gained a large file on Strong herself. Through all this, she stayed committed to the Soviet political project, defending the USSR from anti-communism, but favoring the Chinese more than the Soviets as time went on, especially after the Soviets expelled her.
