French is the principle working language of the Rochambeau Chapter in France.
With the exception of special events, such as the official visits to France of the NSDAR President General, all the chapter meetings and events are conducted in French.
As a general rule, formal written communciation within the NSDAR is in English, whereas French is used for written communication with public and private authorities in France.
Most of the American members of the Rochambeau Chapter are bilingual and many of the French members have a good working knowledge of English. Some of the chapter's associate members residing outside France also speak French. Informal exchanges between members and associate members visiting France are therefore often lively, with members moving easily from one language to the other!
Concerning written communiction with members and associate members: invitations for chapter events are generally in French. However, with respect to the bi-cultural heritage of the Rochambeau Chapter, the chapter agenda, the annual newsletter, brochures and other documents with wide distribution are bilingual.
Electronic communciation is increasingly bilingual...this website is a good example!
