I know 10+ people who are educated, hard-working, and have every qualification yet are denied a simple tourist visa to the US for whatever reason. The process is lengthy, costs a decent amount of money, consists of filling out ridiculous forms on antiquated websites and attaining sponsors from the US, and then results in a 5 minute interview where some prick essentially makes a snap judgement about the candidate. We got lucky once with the tourist visa process, but that was pre-Trump.
The US is an utter embarrassment, and if it weren't for my family still being there, I wouldn't really care much about never going back.
