Book excerpt: The year 2015 marks the 50th anniversary of the passage of the Immigration and Nationality Act (INA) of 1965—a landmark decision that made the United States the diverse nation it is today. In The Law that Changed the Face of America, congressional journalist and immigration expert Margaret Sands Orchowski delivers a never before told story of how immigration laws have moved in constant flux and revision throughout our nation’s history. Exploring the changing immigration environment of the twenty-first century, Orchowski discusses globalization, technology, terrorism, economic recession, and the expectations of the millennials. She also addresses the ever present U.S. debate about the roles of the various branches of government in immigration; and the often competitive interests between those who want to immigrate to the United States and the changing interests, values, ability, and right of our sovereign nation states to choose and welcome those immigrants who will best advance the country.
