Knowledge of a foreign language is helpful, but it is not required. Translators will be provided for public meetings. Obviously, in-depth personal conversations will be limited without foreign language fluency. In some areas (e.g. Europe) the people (especially the younger ones) are multi-lingual and may know some English. Literature in appropriate languages will be provided for distribution. You may be taught a few phrases as well as Christian songs in the language of the country in which you will be serving. It is always a good idea to know these basic phrases: hello, good-bye, please, and thank you.
