A full chamber of judges in Strasbourg will hear McKinnon's appeal against extradition on 28 August. McKinnon lost his appeal in the House of Lords on 30 July.
McKinnon was first arrested in November 2002. The US asked for his extradition in 2005. McKinnon, who has said he would be content to stand trial in Britain, has lost his fight against extradition in every court in the UK.
Claiming that Britain has become "the 51st state of America", he said, "I stand a better chance in Europe than in my own country, perversely."
