Sorry, I was trying to reply to the above comment by structuring it in the same way, but making one minor switch to show how severe the issue can be. Trusting a router may not happen, but trusting a keyboard (as you've pointed out) almost always does.
It looks like it could be a variant of this squashed down to fit in the connector of a cable. https://github.com/spacehuhn/wifi_ducky
If it is, then the computer doesn't connect to a router at all. The USB cable could make itself available as a network that you remotely connect to then execute commands. The cable then types out your commands as it imitates a USB keyboard. Have you ever seen a device or PC that randomly trusts a USB keyboard you plug into it?

Sorry this isn't an answer as I've never thought of going to the US, but someone posted this earlier today: https://hackersurfing.com/2019 I think meeting people in person will greatly increase your chances of landing a job in the US, because that's definitely how it is down here in NZ.
