Another proposal from Homeland Security on identity information seems to be yet another nail in US tourism from over here.Lat year I holidayed in North America - Canada though - and in Hong Kong (which you'd think, being part of the People's Republic of China would be a tricky place to enter, but it wasn't). At Hong Kong aiiport they even have a visitor competition to select the immigration officer of the month.
I used to vist the USA regulalry in the 70s and 80s. Immigration was always diificult despite my date of birth being 4 July. But then your people cancelled my life time visa in line with everyone else's and it got worse. So I don't bother.
Air New Zealand has had to lay on flights via Hong Kong from London rather than expand LA ones due to complaints from their passengers at the highly intrusive immigration processes just to wait in a lounge whilst the plane's toilets are emptied. Hong Kong wins stopover visitors as a result.
So USA, your paranoid civil servants and politicians may protect you from their supposed enemies in Europe but those of us with income to spend on holidays will go to places where, after a 10 or 12 hour flight, we are welcomed by the country and where they won't retain large amounts of information that infringe our civil liberties.
Now I live in an area with probably the highest population of US citizens in the UK thanks to USAAF. Curiously those people do not seem threatened by us and they are totally surrounded by us. So get your government to see sense. Welcome tourists from Europe or kiss their euros/pounds/kroner goodbye - there's plenty of places that want us and our money and that have attractions just as good as the USA.
