An au pair (plural: au pairs) is a domestic assistant from a foreign country working for, and living as part of, a host family. Typically, au pairs take on a share of the family's responsibility for childcare as well as some housework, and receive a small monetary allowance for personal use. Au pair schemes are subject to government restrictions which specify an age range usually from late teens to mid to late twenties. In Europe, where the concept originated, au pairs are only supposed to work part time, and they often also study part time, generally focusing on the language of the host country, but in the United States, they are permitted to provide full time childcare.
