"...and the conviction is now presumably spent."
I don't think you'll have a problem either, but a warning to beware of the term "spent". Spent convictions are those which, under the terms of the UK's Rehabilitation of Offenders' Act (ROA), need not be declared to prospective employers. The period before they become spent is dependent upon the sentence imposed (not the offence). As examples, a conviction which was dealt with by way of a Conditional Discharge is spent as soon as the Discharge period is over whereas an offence which attracted a custodial sentence of more than four years is never spent.
However, the Act is only applicable in the UK. (It also has several exceptions mainly where the job or position involves regular contact with children or vulnerable adults, some positions in the finance industry and those connected with policing or the judicial system.) It has no bearing outside the UK. Foreign countries can ask any questions they deem fit for things such as visas and they must be answered truthfully.
