Operator of Annandale "doumi" business scheduled to be sentenced On Friday, the business's owner, Youn Sok Chang, is scheduled to be sentenced in federal district court in Alexandria. Prosecutors have asked that he face a prison term somewhere between 33 and 41 months, writing in court filings that he harbored more than 25 illegal immigrants to work as "doumi" girls. A stiff sentence, they wrote, might convince others in the same line of work not to hire and harbor those in the country illegally. "There are other doumi companies operating in Fairfax County, and it is likely that they are or will seek to harbor illegal aliens to further their businesses," Assistant U.S. Attorney Michael J. Frank wrote. Undoubtedly, they will pay close attention to the sentence Chang receives. Chang, 40, a South Korean immigrant who prosecutors say has maintained various residences in Falls Church, Annandale and Gambrills, Md., pleaded guilty in May to conspiring to harbor and induce illegal aliens to reside in the United States. According to his plea agreement, he ran a doumi business that employed more than 25 illegal immigrants from Korea, and he housed some of the women who worked for him at homes in Falls Church and Annandale. The business, court filings show, catered especially to customers at Korean businesses in Centreville and Annandale such as Cafe Seouli and Cafe Tuah. Chang admitted in his plea agreement that he charged customers $70 an hour to "converse with, sing, and dance with" the women he provided. The woman would receive $50 of that money, and Chang would receive $20, according to his plea agreement. Prosecutors say the business operated from December 2010 to February 2013. A man who worked with Chang, Taesan Won, pleaded guilty in 2011 and was sentenced to a year and three months in prison in connection with the operation, court filings show. Chong C. Park, Chang's defense attorney, argued in court filings that Chang should receive only two years in prison, saying that Chang was "not a violent man" and his crime did not involve "sex trafficking, prostitution, force or coercion." Park wrote that Chang's alcoholism was "one of the overriding factors" in his breaking the law.
