24 years ago I was convicted for theft, I went to court and was handed a community service order rather than a custodial sentence. I realise that in the UK my conviction will be considered spent and does not need to be declared. However, I would like to travel to the USA and notice that they consider all convictions, however long ago, still valid and I need to provide details of my court appearence to apply for a visa. The court I attended was Bow Street Magistrates, which has since closed down. Where can I go to get the required information to apply for a visa, and how long does each visa last?
