There is an enormous amount of detail in some apparently unimportant topics (for example on how to get a green card for your maid) and very little on very important ones (for example on labor certification). The topic of labor certification is a subsection in the chapter for "Live-In Domestic Workers" !

This book may be good if you are trying to get a green card for your maid, though.

I believe this book may be of interest to many readers.
First of all, it explains how visitors from abroad can legally prolong their stay in the USA. It's possible to apply for an extension of one's visitor's status without leaving the USA. And this book guides well through this procedure.
Secondly, those who are interested in applying for a green card, should find the most suitable category if they want to succeed. The book describes qualifications and outlines the application process for each of them.
Many people don't know that they may be inadmissible for one or another reason even if they otherwise meet all the green card applicant requirements. Someone already in the US, and still may not be allowed to proceed if he or she falls into one of the inadmissible categories - as a violator of immigration rules in the past or for health reasons, for example. Some people find this out only after passing a medical exam. But you may want to learn about the regulations in advance. The book covers this issue in detail, including who and how can apply for a waiver of inadmissibility.
Another sensitive chapter is on cancellation of deportation. How and in what cases this may be done...
Also, you'll find some important information on how and who is eligible to claim status as a refugee or political asylee.
In all, I think the book is pretty informative and filled with practical advice. It's also easy to read and understand.
