Petrova confirms U.S. citizenship application

Russia's Nadia Petrova confirms that she has applied for U.S. citizenship. The 29-year-old, who owns a home in Miami, says that she feels comfortable in South Florida. 

"I like the lifestyle. I like the weather. It's just a perfect place for tennis,” she said at the BNP Paribas Open at Indian Wells. "Everything's so easy. You just come, you need to go to the pharmacy, drug store, it's 24 hours open. Everything is here just for the people, you know. I just feel very comfortable here, relaxed atmosphere, and I don't have to stress. I don't have that crazy traffic like it is in Russia. I don't have those cold winters."
