Honestly I think this is a bit exaggerated. I think that this list describes pretty much the worst case scenario that still results in you entering the country in the end. There's no way they interview every tourist flying in from Europe for two hours.

As far as I know it is also not a requirement to list all of your birthmarks or use the same attire in the visa application photo as the one you're traveling in. These are just "good ideas" that the travel agency think will reduce your chances of being rejected at the border.

I haven't personally traveled to the US after 2025, but I know people who travel regularly (for work though, not tourism). They've complained about a ton of other things, but they haven't mentioned border checks or ICE being weird in any way.

Edit: As an aside, I traveled to the USA just before Trump was inaugurated. I'm from Iran, so naturally I was interviewed at the border. Dude asked me if I was an IRGC member. I said no. He was just so fucking happy and immediately told me to have a nice trip. As I was walking away, he had to call me back to the desk to answer a few more questions that protocol demanded (like, how much cash are you carrying and are you bringing in weird seeds).
