I have just received the following email:

" Starting next week, travelers to the U.S. will have to either get a visa or use a US Gov't website to get advance approval.  Just coming from a "visa waiver country" is no longer good enough. ".

The fun thing here is the following:

" Note that a web search of ESTA may lead you to something like "esta.us" which looks official, but is really a private company trying to charge you money for a service that (I suspect) is the same as the free government-provided service."

I am waiting for the counter-measures from the European Union.
