Tanith Jessica Louise Belbin White (born July 11, 1984) is a Canadian-American ice dancer and Olympic program host for NBC Sports. Though born in Canada, she holds dual citizenship and has competed for the United States since she began skating with Benjamin Agosto in 1998. With Agosto, Belbin is the 2006 Olympic silver medalist, four-time World medalist, three-time Four Continents champion (2004–2006), and five-time U.S. champion (2004–2008).
Tanith Belbin was born in Kingston, Ontario, and raised in Kirkland, Quebec. In 1998, she moved to the Detroit area in the United States and received an immigrant worker visa in 2000. Due to immigration rules at the time, she did not receive a green card until July 2002 and would not have been granted U.S. citizenship until 2007. An amendment was passed which allowed Belbin to be sworn in as an American citizen on December 31, 2005. The amendment was authored by Senator Carl Levin who stated, "This amendment corrects an anomaly in the law that unfairly disadvantaged some people who had begun their naturalization process before 2002. Tanith Belbin began her naturalization process in 2000, but due to changes that were made to the law in 2002, the process has taken significantly longer than it would have if she had filed her paperwork 2 years later."
