Hello, I am an American and have been offered a position as an Au Pair in Lausanne. She was told that it is very difficult to obtain a work permit for a non eu Au pair.. is this true? What type of permit will she have to apply for for me? Also she wants me to live out, so is the work permit what will be necessary for me to rent/sublease housing? Thanks for any help you can offer

... I am trying to work legally this time
