On September 30, 1996, Congress amended the Immigration and Nationality Act by adding a new subsection to the health-related grounds of inadmissibility: “Proof of Vaccination Requirements for Immigrants.” This new subsection requires any person who seeks an immigrant visa to show proof of having received vaccination against vaccine-preventable diseases as recommended by the U.S. Advisory Committee on Immunization Practices (ACIP). The ACIP is an advisory committee to the Centers for Disease Control and Prevention that makes general recommendations on immunizations, including safe and effective vaccination schedules.
