Yousof Azizi, a 40-year-old Iranian PhD candidate at Virginia Tech, was detained by Homeland Security Investigations agents outside his Germantown, Maryland home on April 13 and transferred to an immigration detention facility in Arizona. His wife denies DHS allegations that he lied on his student visa application about membership in Iran's Student Basij Organization and claims his visa status issue was a pretext, asserting he was speaking publicly about U.S.-Iran relations based on his academic research.
