About ten percent of the owners of South Korea’s ten largest conglomerates and their families are found to be American citizens.  
 
An investigative reporting team at KBS surveyed 921 members of the families of the top ten chaebols, and found that 95 of them held U.S. citizenship. Among them are Lee Mi-kyung, vice chairwoman of CJ Group, and Chung Yoon-yi, a daughter of Hyundai Motor Chairman Chung Mong-koo.
 
Of the 95 people with U.S. citizenship, 46 are major shareholders of the respective conglomerates, and 23 of them take part in managing the companies. 

KBS also disclosed the birthplaces for 628 people of the surveyed. By birthplace, 119 were born in the U.S., including Lee Jae-yong, vice chairman of Samsung Electronics and son of Samsung Electronics Chairman Lee Kun-hee. Lee Jae-yong, however, now only holds South Korean citizenship.
 
The portion of U.S.-born family members of the conglomerates was especially large for the younger generations. Of the surveyed, 121 were minors and 38 of them were born in the U.S.
 
The report also revealed that a total of 35 male members of the top ten conglomerates have abandoned South Korean citizenship since 1980, and 23 of them have been exempt from military service due to their newly-acquired foreign citizenship.
