In 1978 she emigrated to the United States, where she became a naturalized citizen. She has taught at the Juilliard School in New York City since 1982. With the spirit of perestroika, she became the first Soviet émigré musician to receive an official invitation from the Soviet agency Goskoncert to perform in her native country. She played concertos, a recital with her son Dmitry Sitkovetsky playing the violin, and chamber music with the Borodin String Quartet to sold-out halls.
