Immigration is a complex issue. Economic, cultural, legal, and security interests all stand in the way of finding a policy solution to manage the flow of immigrants into the U.S.

Immigration has been a touchstone of the U.S. political debate for decades, as policymakers must weigh competing economic, security, and humanitarian concerns. Immigration involves not only jobs and the economy, labor competition, but also culture and national identity. Immigrants come here looking for economic opportunity, freedom, and a better life for themselves and their families. Today, more than 40 million people living in the U.S. were born in another country. Immigration's effect on America represents a choice. Selection criteria can be altered, as can the total number of people allowed into the country legally. The level of resources devoted to reducing illegal immigration can also be reduced or increased. The United States is currently experiencing one of the biggest waves of immigration in its history. International migration is on the rise and remains a fundamental feature of our world.
