"U.S. Consulate Agencies U.S. Consulate Agencies are sub-branches of the U.S. Embassy. These are smaller offices that provide only basic consular services. You may also want to contact a consular agency if you have a specific concern about an incident taking place near that agency.
It is usually best to contact the embassy or consulate nearest you, since that office will be in the best position to offer you help or information. Embassy and consulate contact information is available throughout the MedToGo guide provided with each city’s information."

Die consular agency ist ja eigentlich eher für Leute interessant, die (auch) die US-Staatsangehörigkeit haben - oder aber hier in DTL sind und in die Staaten wollen (wobei man dann vielleicht lieber die Amerikanische Botschaft kontaktiert?)
