In a high security environment, you can get a report from law enforcement; in the Netherlands this is called a "declaration around behaviour" (??), which is basically a signed / authenticated document saying "this person was not involved in financial crimes" - you need to have it specified for a category of crimes, the previous is for example one I had to get to work at a bank as a contractor.

I don't know what the equivalent in the US is, but https://www.fbi.gov/how-we-can-help-you/more-fbi-services-an... seems similar enough.

I'd trust an FBI report more than taking their fingerprints and the like.
