Book excerpt: Given the many ways in which immigration law can affect a single individual as well as as large corporation, most lawyers will encounter a client needing immigration law advice. Yet for the nonspecialist, immigration law can be daunting, particularly because it is governed by a complex mix of statutes, regulations, and federal and administrative court guidance--as well as by adjudicatory policies from multiple administrative agencies. Thus, it is important for lawyers to understand how best to spot immigration issues for clients, and when to involve an immigration attorney for assistance with a client. This book was written by immigration law specialists who insights, guidance, and practice tips can offer help in understanding these issues. The book is meant to provide attorneys working in various areas of law with enough information to identify problematic immigration issues, counsel their clients accordingly and if the matter is advanced to know when to advise the client to consult with immigration counsel. It will also introduce attorneys to the myriad of agencies involved in the immigration process.
