A Southern California pastor has been accused by immigration authorities of helping foreigners fraudulently obtain student visas and handing out phony diplomas at a fake graduation ceremony on a campus where they never attended class, according to the Associated Press. Samuel Chai Cho Oh, 65, surrendered to authorities and faces a charge of conspiracy to commit visa fraud for allegedly charging foreigners cash to help get them student visas on the premise they would attend the Christian university he owns in Fullerton. But more than 100 students from countries including South Korea, Thailand and Japan never took classes at California Union University, which served as a shell for them to stay in the country legally, Immigration and Customs Enforcement officials said. Immigration authorities say Oh charged students between $600 and $10,000 over the last decade to file paperwork on their behalf to certify they had been accepted to the university and would be attending class in order to obtain valid student visas. Authorities said Oh raked in between $40,000 and $50,000 a month from the alleged scheme and acknowledged that 75 percent of the 300 students enrolled at the university did not regularly attend class. Macias said authorities seized two bank accounts belonging to Oh that combined held more than $400,000. No criminal charges have been filed against the students, authorities said. Macias said those who are not eligible to stay in the country legally will face deportation proceedings.
