Jurisdiction for the initial overpayment notice may or may not be the Division of
International Operations (DIO) when a debtor is outside the United States, Puerto
Rico, the U.S. Virgin Islands, American Samoa, Guam, and the Northern Marianas.
DIO always has jurisdiction when full refund is not received in response to the initial
overpayment notice and followup refund efforts are necessary.
DIO generally has jurisdiction when adjustment is available against benefits due someone
outside the U.S.
