I’m concerned about going to the US for the same reasons why I’m concerned about family coming to Canada: dealing with US customs.
However, they’re US citizens so I can’t imagine that they’d have paperwork to go back to the US. Then without paperwork to make mistakes on, they should be less likely to get incarcerated, right?
I’ve used a non-touch DisplayLink USB monitor before. You might run into issues with getting it to work properly based on your OS. DisplayLink and Debian were not friends, and took a lot of messing around with drivers and other apps to get it to work. I can’t speak for other OSs though
