I've visited the US seven times between 1986 and 2015, staying up to three weeks at a time, and always enjoyed my visits. I had varying experiences of immigration control, from outright hostile and suspicious in New York in early 2000s, to surprisingly friendly in Seattle in 2015.
But I wouldn't go now. I dislike and distrust the country's leadership which specialises in insulting, belittling, patronising and threatening the rest of the world, while giving an easy ride to warmongers like Putin and Netanyahu.
Those of us outside of the country can register our feelings in several ways, two of which are to not visit the place, and to not buy Tesla cars. I'm intending to avoid both in future, not that that involves much personal sacrifice!
