when I came in back in 2016 I had over 20,000 dollars, me and the wife, didn't think it was an issue, didn't know about the reporting of money, got sniffed out by a dog at the airport in Minneapolis, got ran over the coals by the agent in charge, he let me know about the $10,000 dollar per person declaration, said he didn't care how much I took with me just had to report it. And yes he said he could have taken it if he wanted too.
