Teach English, German, French, or another prestigious language to students, professionals or others in Central Asia. In this way you can develop relationships that will hopefully provide opportunities to informally share Christ’s love and truth in this country, which has very few believers. Also spend some time studying the local language.
Qualifications: Native speaker of, or very advanced in, the language you want to teach; secondary school diploma or, preferably, bachelor’s degree; teaching certificate - general or language-specific (e.g. TEFL); teaching experience preferred; interested in other cultures.
