I think you're responding to a comparison I didn't make. My point wasn't that the US is uniquely difficult compared with the UK or Australia. My point was that legal immigration is difficult, stressful and often misunderstood, including for people who are clearly trying to contribute and follow the rules. I'm aware the UK system has become much harder since I used it, and I'm not disputing that. But "other countries are harder" doesn’t make my experience nonsense.
