President Lee Jae Myung said Thursday the government will explore ways to lower the age threshold for overseas Koreans' dual citizenship, which is currently limited to those aged 65 and older. Lee made the remarks during a ceremony marking the 19th World Korean Day, which brought together some 370 participants, including leaders of Korean communities from around the globe. Under the Nationality Act, overseas Koreans are permitted to hold dual citizenship only if they are at least 65 years old. The overseas Korean community has long demanded lowering the age limit so that younger economically active generations can also benefit. World Korean Day falls on Oct. 5 and has been designated as a commemorative day since 2007.
