Radcliffe stopped from entering US due to visa problems

Los Angeles: `Harry Potter` star Daniel Radcliffe was initially denied entry to the US due to visa problems.The 25-year-old British actor was stopped by American border guards while returning to the US for Comic-Con after attending a premiere of his new movie `What If` in Toronto, suggest reports. Radcliffe was in the process of upgrading his current P-2 visa to an O-1 visa. P-2 visa is designed for foreign actors as well as entertainers and gives the performers residency right for the time they`re working on a project but cannot exceed a year. The actor fortunately managed to get his visa upgraded and arrive on 2 AM in San Diego. He was in time for a scheduled Comic-Con panel later on July 25 afternoon with his co-star Juno Temple and director Alexandre Aja to discuss his film `Horns`. Radcliffe stars as the protagonist in the adaptation of Joe Hill`s horror novel of the same title, playing Ignatius Perrish, a young man who grows horns after a mysterious death of his girlfriend.
