State of Emergency: The Third World Invasion and Conquest of America - Patrick J. Buchanan

The U.S. has experienced extremely high levels of immigration since passing the Immigration Act of 1965 and more people come every year. Buchanan discusses our historical relationship with Mexico, historical immigration patterns in America, problems in both U.S. and Europe, and what should be done to cut the flow of illegals into America. It's a very informative book.
