A concise, legally accurate guide by a qualified Irish immigration professional. This short guide is written for Americans who are eligible for Irish citizenship by descent and want clear, legally accurate information without internet myths, forums, or guesswork. I am a qualified legal professional working in Irish immigration. I wrote this book because most guides available are either inaccurate, bloated with filler, or written by people with no formal training in Irish nationality law. This book is intentionally concise. It explains exactly how to qualify, by descent, association / nationality or residence, what documents are required, how applications are processed, and the most common mistakes that cause delays or refusals. If you are looking for a legally accurate overview written by someone who understands the Irish system from the inside, this guide will save you time, confusion, and unnecessary expense. This book is not a substitute for legal advice, but it will give you a clear, reliable understanding of all avenues to acquire Irish citizenship and how the process works in practice.
