At German Joys, Andrew Hammel has an entry with useful links on doing an LL.M. in the USA. He refers in particular to a book in German on the topic by three German lawyers: Der LL.M.

It was written by three young German lawyers who have had experience with various programs. I haven’t had time to read it yet, but it seems pretty thorough. Subjects covered: how an LL.M compares with other postgraduate programs; how to select an LL.M program; deciding which country to go to, and arranging financing. In addition, there are “experience reports” from people who have attended LL.M programs in the UK, South Africa, Germany, New Zealand, and the U.S. A section in the middle provides examples of CVs, letters of recommendation, and application essays.
