I've just received a newsletter from the International Airline Passengers Association (IAPA) that includes some interesting information about getting into the US without any immigration hassle. "Citizens of the United States, Canada, Bermuda and Visa Waiver Pilot Program countries (such as Australia, France, Germany, Japan and Great Britain) who travel internationally on business at least three times a year are eligible for INSPASS."
Our regulars who are eligible are probably already aware of the program (and since Switzerland isn't mentioned, I don't know if Rudi is). If you're not, though, respond and I'll post more detail.
