The U.S. gave Swiss banks too much grief a couple years back for them to want to keep accounts for Americans who weren't living in the country. It was a fun novelty while it lasted.
Since returning to the States, I've had a lot of requests for advice on getting a job overseas. To answer most of those questions, I wrote an ebook. Click here to download.
Hopefully, it's more useful than self-indulgent. Enjoy.
