The book is designed to allow you to quickly find a rule and obtain immediate guidance on key issues. It includes: eligibility analyses designed to provide a short review of the requirements for any given visa petition; practice pointers designed to provide quick access to difficult issues that may arise; checklists that will guide practitioners as to what to include in a petition; and common immigration acronyms with an easily-referenced Acronyms section.
