it. She believed that it was unfair to bend the requirements for U.S. citizenship for Belbin, when other "aliens of extraordinary ability" were denied expedited citizenship. Ultimately, by a special act of Congress sponsored by Senator Carl Levin (D-MI) that passed on December 28, 2005, which President George W. Bush signed on December 31, 2005, Belbin became a naturalized citizen, allowing her to compete for the United States at the 2006 Winter Olympics. In January 2006, Belbin / Agosto won their third consecutive national title and qualified for the Olympics. At the Turin Olympics, Belbin and Agosto won the silver medal in ice dancing, the first American ice dancers to win an Olympic medal in 30 years. They went on to win the bronze at Worlds. Belbin / Agosto began the 2006–2007 season with a free dance called That's Entertainment but arrived at Nationals with a new program to the music of Amelie. They won gold at Nationals, the silver medal at Four Continents, and the bronze at Worlds. In 2007–2008, they won gold medals at both Skate America and Cup of China which qualified them for the Grand Prix Final, where they took the silver medal. They won their 5th national title and then placed 4th at the 2008 Worlds after a fall by Belbin in the compulsory dance. Belbin / Agosto were regular cast members of the Champions on Ice tour from 2004 until COI went out of business following the 2007 season. They were guest stars on part of the 2008 Stars on Ice tour. In April 2008, Belbin / Agosto left Igor Shpilband, who had coached them for their entire partnership, and began working with the married coaching team of Natalia Linichuk and Gennadi Karponosov at the IceWorks Skating Complex in Aston, Pennsylvania. In addition to teaching different technique, Linichuk advised Belbin to gain 10 pounds and develop some muscles in order to skate faster and more fluidly. This also gave Belbin more core strength to hold her positions better, thus making lifts easier for Agosto. Belbin / Agosto began the 2008–2009 season at the 2008 Skate America and 2008 Cup of China, winning silver at both competitions. They withdrew from the 2008–2009 ISU Grand Prix Final after the original dance due to a back injury to Agosto. They withdrew from the 2009 U.S. Championships before the event began due to Agosto's injury. They were named
