Alex Nowrasteh is Senior Vice President for Policy at the Cato Institute and one of the most cited and combative voices in the U.S. immigration debate. A self-described 'radical' for open borders, he turns the standard fears about immigration - crime, terrorism, welfare, wages, culture - into testable claims and then publishes the numbers. He co-wrote the prize-winning 'Wretched Refuse?' and the rebuttal handbook 'The Most Common Arguments Against Immigration and Why They're Wrong,' and he is a regular on Capitol Hill, on cable news, and across the op-ed pages.
David J. Bier is the Director of Immigration Studies at the Cato Institute, where he holds the Selz Foundation Chair in Immigration Policy. A relentless data-driven analyst of legal immigration, border security, and interior enforcement, he is best known for showing that fewer than 1 percent of people who want to move to the United States can legally do so, and for the Powerball analogy that reframed the legal-immigration debate. His research has been cited by the U.S. Supreme Court and multiple federal appeals courts, and he testifies regularly before House and Senate committees.
