I've been through this multiple times. Basically they just come out to your neighborhood and ask your neighbors if they've noticed anything suspicious going on. Strange behavior, odd visitors, unexplained affluence, etc. Takes all of 5 minutes. If it were my job to vet people, I suppose I'd be doing the same sanity-checks to make sure I wasn't dealing with an unstable person: drug addict, wife-beater, etc.

And then would you retain the details forever?

I've been on other side of the coin as well. Agents came to me asking about another person. They tell you up front that it's voluntary to speak to them and that anything you say can get back to the person under investigation if that person asks for the investigation records. All in the open.
