Book excerpt: U.S. immigration policy is governed largely by the Immigration and Nationality Act (INA). The United States has long distinguished temporary immigration from permanent immigration.

Permanent immigration occurs through family- and employer-sponsored categories, the diversity immigrant visa lottery, and refugee and asylee admissions. This book looks at key issues concerning visas.
