According to the Korean Driver’s Licensing Agency, if you are staying in Korea for more than 90 days and have registered as a foreigner, you can exchange your U.S. driver’s license for a Korean license if you submit a notarized affidavit personally attesting to your U.S. license’s validity and state of origin. Please note that the U.S. Embassy cannot certify the authenticity of your U.S. driver’s license. However, if you have a valid, unexpired U.S. driver’s license, you may get a notarized affidavit. Please note that as of December 31, 2011, this is a service only available to U.S. citizens. The U.S. Embassy in Seoul will no longer provide notarized affidavits to non-U.S. citizens for driver’s licenses.
