Authentication process for documents being sent to the Taipei Economic and Cultural Representative Office (TECRO) or local Taipei Economic and Cultural Offices (TECO) in the U.S.
Only U.S. federal government or federal court documents need to be authenticated by the U.S. Department of State before being submitted to the Taipei Economic and Cultural Representative Office in the United States (TECRO).
