Which is the suitable task that an au pair may do in the house?

What is an au pair? An au pair is a single girl without any dependants who comes to the U.K. to learn English and to live as part of an English speaking family. She is not a domestic servant but may help in the house for up to 5 hours a day for pocket money. Suitable tasks would be light housework and taking care of children. She should have one day each week completely free and she should be free to attend language classes and religious services if she wishes. Pocket money should be between 15 and 20 pounds per week and she should have her own room.
    Before she arrives she should have as much information as possible about the home she is going to and what she will be expected to do. She will find it helpful to have a letter from her hostess explaining the arrangements to show the immigration officer when she arrives.
    An au pair must be a single girl aged at least 17 and no older than 27 when she first becomes an au pair. She must be a national of a Western European country, which includes Malta, Cyprus and Turkey. The longest a girl may stay in the UK as an au pair is two years.
    An au pair who is a national of, a country which is not in the Commonwealth or European Community (EC) and who is admitted for longer than 6 months will normally have to register with the police. This will be shown in her passport. She must take her passport and two passport-size photographs to a police station. She will have to pay a fee, about 25 pounds.
    If an au pair wishes to stay longer than the time stamped in her passport she may apply either by post to Lunar House, Croydon, or in person at one of the Public Enquiry Offices.
