Canada

We DO need them, but we don't deserve them. Canada is pretty. I honeymooned in Quebec City.

This would send my wife off the deep end. Don't do this, Orange Fat Man.

They're a scientist. Science is pretty international and often involves travelling to all sorts of countries for conferences with other researchers in your field.

This. I personally have no plan going to usa now and in the future. Unfortunately some Canadians may still have to go for work related trips. Just be aware that you may or may not need to register in the new "Alien Registration Requirement".

I have a question for you, do you actually need REAL ID to travel domestically?

This is the only solution. I would rather eat nails than go to the States again.

They never asked to see my phone at the border. But the last time I crossed they were getting a hell of a lot more aggressive. They got less aggressive when I became a Canadian citizen, but when I only had my Lebanese passport they almost always brought me in for more questioning. It was kinda bizarre. They probably aggressively searched my luggage, but I can't be sure of that.

While technically true, they weren't kicking out foreign visitors for being critical if the president.

I used to train people in a specific culinary technique, and i had clients from all over the world, including Muslim clients from the Middle East and India. Most had no problem visiting, but one was stopped at the border and heavily grilled.

His visa said he was here for vacation and educational purposes, but when they went through his texts, they determined that he was here for business purposes, and threatened to confiscate his cash, and reject him from entering the country.

After a few hours, he eventually convinced them that he had considered his training with me to be educational rather than business for his visa, and it just an honest mistake, with no nefarious purpose, and was finally released so he could visit me, and get his training.

This was about 10 years ago, and I don't remember who was president. It was either Trump or Obama.

Bingo. If anything, use of a burner phone will be purposely misconstrued as "suspicious", and used as justification for more thorough screening.

"You just got it last week? That's weird, we usually only hear drug smugglers using new phones. You're not smuggling fentanyl, are you? OK, so you won't mind if I take a look through your luggage to be sure, right? Maybe I should send you to secondary screening for an x-ray."
