Belbin/Agosto won the silver medal at the 2005 World Championships. Their silver medal combined with the placement of the other American team earned the United States three spots to the Olympics in ice dance, the first time this had happened since 1984. By a special act of Congress that passed on December 28, 2005, which President Bush signed on New Year's Eve, 2005, Belbin became a naturalized citizen of the US, making her able to compete for the United States at the 2006 Winter Olympics. Belbin/Agosto went on to win the Olympic silver medal in ice dance on February 20, 2006. They were the first American ice dance team since 1976, the first year ice dancing was contested at the Olympics, to win an Olympic medal.
