SOCCEROOS fans who plan to support Australia in the World Cup play-off against Honduras may have to explain to American authorities why Ange Postecoglou should not be immediately sacked and list the advantages of a 3-5-2 formation if they travel to San Pedro Sula via the United States.

The American inquisition comes as Football Federation Australia says it may sell seats to fans on a charter plane it is considering to carry the Socceroos across the Pacific to ease its own travel and logistics woes.

Although Australians typically enter the United States on the Visa Waiver Program, recent changes to US law - signed by President Obama last year - require that individuals who have travelled to Iran must obtain visas and attend an in-person interview at a US embassy or consulate to explain their reason for travelling to the Persian Gulf
