Homeland Security officials say Ian Roberts built a long criminal record while living in the U.S. illegally, with arrests for narcotics and firearms possession; In addition, Roberts' immigration history includes two visas, four Green Card applications and subsequent denials, and several trips abroad, authorities said. He entered the U.S. through John F. Kennedy International Airport in New York on a B-2 non-immigrant visa and was classified as a visitor for pleasure. He left the U.S. on an unknown date but returned before his 1996 arrest for narcotics possession. He re-entered the U.S. through San Francisco in 1999 on a student visa, which expired in March 2004, DHS said. He left and then re-entered the U.S. at least two other times on a student visa.
