Had a coworker that found that out the hard way. Got a DUI and didn't tell anyone. Then one day a few months later had a work trip in Canada. They stopped him at customs in Canada and shipped him back. Company had to fly someone else out there on short notice.

Still better than the coworker that flew to Canada on business and then while on the trip his name got added to the "NO FLY" list. That was a fiasco.

A coworker of mine went to Pakistan and then was not allowed to come back for quite a while. I don't know if it was the proverbial "no fly" list or something else, but eventually he was allowed back.

I remember reading about someone who was denied entry to Canada because they brought anti-depressants with them.

You have no rights traveling across borders, and it's not just US officials that are arbitrary and unreasonable.
