Paul is also a visiting clinical lecturer in law at the Yale Law School, where he co-directs Yale’s Supreme Court Advocacy Clinic.

In listing Paul in its nationwide rating of appellate lawyers, Chambers USA (2021) notes that he “has a flourishing reputation for his appellate work,” that he “thinks at least five steps ahead of others,” and that “his integrity and experience shined through everything he did or said.” In ranking Paul as a “Leading Lawyer” in appellate practice, The Legal 500 describes Paul as “exceptionally professional, effective, and easy to work with,” an “intellectually impressive and skilled advocate,” and it explains that he “demonstrates a surprisingly high policy awareness that sets him apart in Washington.”

Before the Supreme Court, Paul won a pair of immigration cases in 2020—Nasrallah v. Barr and Guerrero-Lasprilla v. Barr—both of which extended the scope of judicial review over administrative agency action. Crucial to Paul’s victory in Nasrallah was advancing a statutory interpretation argument that had been overlooked by all ten courts of appeals to have previously addressed the issue. In 2019, Paul won a unanimous victory—with divided reasoning—in Kisor v. Wilkie, a landmark administrative law case that imposes significant limitations on the scope of agency deference. In 2018, Paul secured a 9-0 win in the bankruptcy case Lamar, Archer & Confrin, LLP v. Appling, which presented a technical question of statutory interpretation.

Paul frequently challenges administrative agency and other government action, especially with respect to high-skilled immigration, the life sciences and healthcare industries, and taxation. In October 2020, Paul won an injunction for the National Association of Manufacturers and the US Chamber of Commerce, enjoining implementation of a presidential proclamation that would have barred tens-of-thousands of high-skilled workers from entering the United States. In December 2020, in US Chamber of Commerce v. DHS, Paul won vacatur of two regulations designed to substantially upset high-skilled immigration. In 2021, the American Immigration Lawyers Association awarded Paul the Jack Wasserman Memorial Award for excellence in the field of immigration litigation.

In 2018, Law360 named Paul an “MVP” for his intellectual property work before the Federal Circuit, where he has argued about a dozen times. Paul also has deep experience with the False Claims Act, civil rights, and securities law.

Paul served as a law clerk to the Honorable Diana Gribbon Motz of the US Court of Appeals for the Fourth Circuit. He was a senior editor of the Yale Law Journal.
