The United States has been a land of immigrants ever since its founding. But what is it like to immigrate here and who is allowed to do so? In this book, you'll get to follow the stories of several immigrants as they make their way through the immigration process. From green cards (permanent resident cards) to naturalization (the process of becoming a United States citizen), you'll get a first-hand look at what services are available to immigrants along the way and what roadblocks some people might encounter. This book explains exactly what it's like for a person to immigrate to the United States in the 21st Century.
