The main purpose of this legislation is to create a national registry for Korean American families who have been separated from relatives in North Korea since the Korean War. The goal is to facilitate future reunions between these families and their loved ones, whether through in-person meetings or video calls. Key provisions of the legislation require the Secretary of State to gather information on Korean American families seeking reunification with their relatives in North Korea. This includes establishing a private registry that contains the names and relevant details of these families.
