Re: Travel to or through the US?
Well, this has been going on for years, so nothing new. And no, I do not really plan to go to the US, though I miss my friends there, and I would really love to see some of the national parks. I dislike, however, the way the country went under the past administration, and I am deeply worried about some developments - but let's not get political here. I usually had my laptop with limited personal data on it, and ditto a pretty clean cell phone (still do that, it is not running my life, thank you), though that is not always an option.
I did travel to the US quite often in my past job (so much I usually messed up the "when were you last in the US?" first question when entering - dude, you are looking at the stamps, there's a bunch, I'm a regular visitor, as should be noted in your computer as well). I have usually been treated very professionally, so I won't say anything against the people I interacted with. They have also been very helpful when we did have a very tight connection (due to delays), opening a fast line for those passengers.
Only once, when I was traveling through the US to Canada, and had to make a connecting flight, and was still a student on a student visum, I was questioned in a small room. I'd say it was still respectful enough, and I did make the connection. But actually it was none of their business - I was going to Canada after all. I guess it was because I'm a physicist, had a pilot (for real planes, i.e. gliders, no engine to cover your mistakes) license, and it was September 2002...
