Northwest Asian Weekly recently published a list of Asian Americans in the Sochi 2014 Olympics. While figure skater Mirai Nagasu is not going and snowboarder Chloe Kim cannot go, ice dancers like Alex and Maia Shibutani, Madison Chock, and Felicia Zhang are. The article mentions that short track skater J.R. Celski is half Filipino. John has already mentioned that hockey player Julie Chu will be at Sochi.
I like how the article also points out Paralympic competitor Jen Lee, who is a member of the Paralympic sled hockey team. Lee is an active duty Army Sergeant who began exploring adaptive sports after part of one of his legs was amputated after a motorcyle accident. The Sochi 2014 Winter Paralympics opening ceremonies are on March 7.
Asian Canadian figure skater Patrick Chan is returning to the Olympics and is a favorite to win a gold this year. Other Canadians of Asian decent include snowboarder Katie Tsuyuki and the freestyle skier Yuki Tsubota.
