Kim attended high school at the prestigious Fiorello H. LaGuardia High School of Music & Art and Performing Arts, a public high school located in Manhattan. From there, she went on to study drama at the London Academy of Performing Arts and later earned her BFA degree in drama at Boston University. Kim has remarked that in her zeal to become Americanized quickly, she studied acting, academics, and pronunciation with equal intensity. She is also a trained dancer and martial arts fighter.

After graduation, Kim devoted herself full time to acting. She garnered several minor parts on MTV, in soap opera-style dramas on ABC, and on the off-Broadway stage. In 1997 she starred in Splendid Holiday, a Korean TV drama being shot on location in New York. In part, due to this experience, Kim decided to return to Korea. She was quickly cast in the TV drama Wedding Dress and was also invited to act in Lee Kwangmo's feature Spring in My Hometown, although she ended up not taking this role. Her breakthrough debut came in the 1999 film Shiri, South Korea's first blockbuster film. Shiri became the highest-grossing film in Korean history at the time, making her an instant star throughout the country. In November 2000 she continued her association with KangJeGyu Film in the big-budget The Legend of Gingko.

After acting in a Japanese film and a low-profile feature set in Los Angeles, Kim appeared in the big-budget sci-fi feature Yesterday, which ended up bombing spectacularly at the box office. Then in 2002, Kim took the lead role in Ardor, the feature film debut of acclaimed documentarist Byun Young Ju. The film was invited to screen in a non-competitive section at the 2003 Berlin film festival, and Kim's acting earned widespread praise.
After a couple of quiet years, in 2004, Kim started appearing on the popular U.S. television series Lost, which introduced her to audiences in the US. She was on the show for all 6 seasons.
