The US does not have such a system of 'spent' convictions. Therefore, it doesn't matter how long ago the offence was committed, you must declare it if you're applying for a visa.
Other countries aren't quite as strict, Australia generally has 10 years but it's better to declare than not. (Crew or otherwise).
