How to visit the United States

Hello my beautiful friends! Here I am with some advices if you want to visit the United States and you want to organize everything by yourself. 

Living in the US as an au pair

Before leaving I had never heard about being an au pair. I read that short paragraph that explained what being an au pair means and that this job gives the opportunity of living in the US for free. Since I have been living in this "world" for almost 2 years I sometimes forget that many people don't even know about it. I still have to explain to my friends when they ask me " What are you doing there?"
