Many countries do things radically different than America does in terms of immigration, but it is quite clear over the past 20 years that one major political party in America favors more open immigration than the other. Where it seems most Americans prefer something right in the middle. Legal, but flexible.

Europes permissive immigration policies (basically anarchy from my perspective in the UK) are creating an entirely avoidable crisis. I expect a far more closed border policy in the future. International travel will become more complicated as western countries will increasingly try to control who is allowed in. Trumps administration is just 2 to 5 years ahead of everyone else.
