天美麻豆

I live in Paris I am 15 years old but after my BEP or my baccalaureate so either in 2 years or in 5 years I want to live either in New York or in Chiago but I need information on the steps I must take. I don't have any family there so I'll have to fend for myself in youth hostels all together. I need the opinions of people who have already had this experience or people who left France and went to live there.
