Yoo Seung-jun

Steve Sueng Jun Yoo, also known as his Korean name Yoo Seung-jun, is a Korean-American singer and actor who became one of South Korea's most popular K-pop singers after his debut in 1997. Yoo's singing career ended in 2002 when he was accused of evading South Korean mandatory military service by becoming a U.S. citizen. He was subsequently banned from entering South Korea, becoming the only person in history to be banned from the country for acquiring another citizenship. Since then, Yoo has been working as an actor in China.
