What does « au pair » mean?
Next year, I hope go to the USA to be « jeune fille au pair ».
In exchange for a free room, board and laundry, I’ll help parents to take care of their children and I’ll do some housework [<em>collective word]</em>.
I hope I’ll discover a new and interesting culture. I also want to meet many people.
I am a little worried because I am scared that my host family might be a little strange. But in the USA, the "au pair" program is very good because an association will accompany [<em>better word could be "support"</em>] me throughout my stay.
Until I go to the USA, I am trying to improve my English gradually. [<em>not sure what you mean by "prepare my file"]</em>

<em>Have a good time in the USA. Well done.</em>
