According to Judge Kim of Seoul's Supreme Court, he dismissed Yoo Seung Joon's appeal of filing a lawsuit for his visa denial and restricted him from entering Korea.
In September 2015, the singer requested an overseas visa through the Consult General of LA; however, his request was rejected. During that time, a representative of Yoo stated, "It has been over 14 years as his visa application continues to get declined. It is his right to fight back regarding his entry into his country."
The first trial was held in September of last year, where his demand was turned down. The judge at that time commented, "If Mr. Yoo were to enter and resume his entertainment activities, much of the military personnel here would be deeply affected by his actions."
Meanwhile, Yoo Seung Joon applied for a U.S citizenship back in January of 2002 and pleaded numerous times saying he would "serve in the military". It seems he is now permanently banned from even requesting any legal appeals.
