"As it's a driving offence rather than criminal,..."
Driving offences are criminal, Tony. Many are "non-recordable" but Dangerous Driving is not among them. It carries a maximum two year prison sentence, a mandatory ban of at least twelve months and an extended re-test must be taken when the ban is over.
The OP's licence will have to be surrendered if he is convicted and even if it was not I doubt he would be able to hire a car in the USA (or indeed anywhere else) with a UK ban for DD still in force (though he has not said he intends to do so).
