Lennon, who had previously been refused entry to the US, used his friend Andrew McMaster's passport to travel to New York in September. He used a self-check-in kiosk to board the flight at Heathrow, and was allowed through when the document was checked in the bag-drop area.
But when he arrived at JFK, customs officials who took his fingerprints realised he was not McMaster. Lennon was asked to attend a second interview but left the airport, entering the US illegally.
He stayed one night and travelled back to the UK using his own passport, which bears the name Paul Harris. The EDL leader uses several aliases.
