Less than a week after her return from space, Moscow hosted the International Women's Congress on 24 June where Tereshkova and Bykovsky were greeted by a gathering of about 2,000 women from 119 countries. Of all the Russian cosmonauts, Tereshkova received the most requests to visit foreign nations. Her trips in particular required pre-approval from the Ministry of Foreign Affairs, the Ministry of Defense, and the KGB and were ultimately authorized by the Presidium of the Central Committee of the Communist Party, the highest political bureau in the Soviet Union.
