Carl is a Partner in Fragomen’s Washington, D.C. office, where he focuses on immigration compliance counseling and enforcement defense, legislative and regulatory representation on key immigration policy issues, federal court litigation of civil immigration disputes, and management of complex immigration cases—including alien investor visa programs, agency allegations of petitioner fraud, and serious allegations of inadmissibility. A veteran of major law firms, Carl regularly teams with lawyers specializing in white-collar investigations, civil litigation, corporate transactions, and global tax minimization to achieve client goals.

Carl has been at the forefront of immigration reform and agency policy since 1983. He began his career as counsel to the Senate Subcommittee on Immigration and Refugee Affairs, and helped draft and negotiate both the Immigration Reform and Control Act of 1986 and the Immigration Act of 1990. In private practice, Carl worked to amend the 1996 Illegal Immigration Reform and Immigrant Responsibility Act to narrow the strict liability elements of the Special Counsel's statute, and to create electronic employment verification options for industries targeted for immigration enforcement. Carl has remained active in advocating for immigrant and employer rights as legislation and enforcement schemes have changed over the years. He also has extensive knowledge and experience related to preventing and responding to ICE enforcement actions.

Carl has represented parents and families pro bono in litigation under the Individuals with Disabilities Education Act (IDEA), as well as numerous organizations and individuals seeking to protect the rights of foreign nationals in U.S. immigration proceedings.
