The once-popular Korean singer, Steve Yoo, known as Yoo Seung-jun here in Korea, may be allowed to enter Korea for the first time in 17 years.<br />An appeals court ruled today that it was a violation of procedure to ban him from entering the country during that time.<br />Yoo caused public uproar after giving up his Korean citizenship for an American one in 2002, which critics thought was to avoid military service.<br />In 2015, he sued the South Korean consulate in Los Angeles for refusing him a visa a case he lost in the Seoul High Court.<br />That ruling was reversed today.<br />The High Court was ordered by the Supreme Court earlier this year to reconsider the case, saying Yoo should not be refused a visa just because there had been a decision to ban him in the past.<br />
