I bought this book as a guide as I am currently considering moving to the US. However this book begins as a tourist plug giving reasons to go to the US (which I'd think you already have if you're considering this book) and ends as a guide to things which most people have no trouble with.
It appears to have been written before the age of the internet - despite having been re-printed last year, as it gives space-age definitions of a "search engine" and rarely gives websites for further details.
The rest of the book gives largely pointless advice, instead referring you to US TV shows for a 'good idea of how the US legal system works', or spending 2 pages discussing how to buy shoes in America.
Do not buy this book unless you have excessive trouble carrying out these basic tasks.
