The judge investigated the charges Do Kwon faces in South Korea before he is sentenced in the United States.

Do Kwon is scheduled to be sentenced in New York on Thursday after pleading guilty to two felony charges, but the presiding judge is urging prosecutors and defense lawyers to clarify his potential situation in South Korea. In documents filed Monday, U.S. District Judge Paul Engelmayer requested both sides to detail the charges and the "maximum and minimum sentences" Do Kwon could face if extradited to South Korea.
