If his father was in the Air Force stationed in Korea %26amp; he mom %26amp; dad

were married, he should be able to get his birth certificate through the

Air Force or the hospital where he was born if it was not on base. He

needs to check with his dad or the Air Force. It will be a long process

so be patient.
