Interested in attending school in Paris.

So, I am a junior in high school right now and I am interested in attending college in Paris, France. There are so many processes and procedures I know I have to go through in order to do this, and I have been researching for months now, but I just cannot seem to find a step-by-step process that will lead me in making my dreams come true. Everything is so, so confusing and intricate. There is a slight language barrier currently, but by the time I depart for Paris, there won’t be.

My intentions for doing this are not only because Paris and the French language hold special places in my heart and family history, but I have HEARD that coming to NYC from training in Europe is such a heavy trait that sets you apart from other candidates when running for an internship. Also, what a better place than Paris to help me with my internship in fashion? Anywho, depending on my outlook on my future by the end of my stay in my Parisian school, I will either come to NYC and try and make it in the publishing world there, or I will stay in Paris and fulfill the same dreams there in the city.

Basically, my question(s) is/are: how do I even make these dreams of mine come true? Is there anyone out there in my situation or has been in my situation that can help me? What step-by-step process can I or do I need to follow?

P.S. If it helps, the school I have chosen is ENSAD and I will study graphic design.

Thanks!
