Greg Boos is the founder of Cascadia Cross-Border Law, a firm recognized for its expertise in US immigration matters. With decades of experience navigating complex immigration issues, Boos has earned a reputation for integrity, innovation, and advocacy in cross-border law. His work has influenced national immigration policy and helped countless individuals and businesses overcome immigration challenges.
For the last 30 years, The International Who’s Who of Corporate Immigration Lawyers has listed Mr. Boos among the world’s top US immigration practitioners. Additionally, for the past 12 years, Martindale-Hubbell has awarded him its highest rating—AV Preeminent—reflecting outstanding professional excellence based on peer evaluations.
Mr. Boos served as counsel for Bob Boule in the problematic Egbert v. Boule (142 S. Ct. 1793, 596 U.S. ___, 213 L. Ed. 2d 54), decided by the U.S. Supreme Court in 2022. Justice Thomas authored the majority opinion in which the Court held that federal agents operating at the border are immune from civil liability, regardless of the nature of their conduct.
Justice Sotomayor, in her dissent, described the decision “… as disturbing as it is wrong.”. Her words highlight the Court’s departure from constitutional principles and its implications for accountability and human rights.
During his representation, Mr. Boos discovered Boule’s extraordinary dual role as a Department of Homeland Security informant and a clandestine guide for asylum seekers – Boule operated a bed and breakfast in Blaine, Washington, aiding US authorities in intercepting millions of dollars in illegal narcotics and helping over 1,000 refugees to Canada.
This backdrop underpins the forthcoming nonfiction book Smuggler, co-authored by Greg Boos and Reece Jones and scheduled for release on October 20, 2026, by Prometheus Books. The book explores the complexities of the US–Canada border, blending accounts of drug enforcement and refugee journeys with incisive commentary on US border policy. Provocative, timely, and deeply researched, Smuggler challenges conventional narratives about migration and enforcement.
HBO has options pending to adapt Smuggler for a television series—read the book before the story hits the screen.
