[10] Yoo led a troubled life during his teen years until he joined the church choir, where he found a passion for singing.
[9] He made demo tapes of his rapping and dance skills and sent these to Brothers Entertainment, where he was eventually scouted and left California to start his career as a singer.
In 2000, he began to expand his career into China and Taiwan, with the release of the single "Can't Wait", which was a collaboration with Taiwanese singer Yuki.

[citation needed] On November 21, 2018, Yoo attempted to make a comeback in the Korean entertainment industry with a 5-track extended play album titled Another Day originally set for release on December 5, with the pre-release title song "Another Day" and accompanying music video set to release on November 22.

[24] On May 19, 2015, Yoo held a live stream through AfreecaTV apologizing to the Korean public and addressing his reasons for pursuing citizenship in the United States.
[26] In 2020, Mo Jung-hwa, the chief of the Military Manpower Administration, stated that Yoo appearing on South Korean broadcasts as a figure in the entertainment industry would create a "risk of lowering the morale" of South Korean citizens performing military service and affect their "willingness" to fulfill their duties.
[37][38] Following this, Yoo attempted to apply for a visa again, but the Consulate General of Los Angeles again rejected the application on July 2, 2019, causing him to file a second lawsuit with the Seoul Administrative Court in October 2020.

[29] However, the court ruling was separate from the South Korean government's ban, and Yoo attaining a visa did not indicate he would be allowed back into the country.
