Why did Maria leave Siberia for the U.S.? Why didn't her mother go with her? How did this separation affect her?

Explanation

Maria was brought to Florida in the US by her father, Yuri, to get trained as a professional tennis player and reach great heights of success and stardom in this sport. Her mother, Yelena, did not go with her because of visa restrictions. This two-year separation was too painful for the young girl. But Maria endured this sacrifice to pursue her dreams.
