Bonjour
J'ai une lettre de motivation à rédiger pour un programme d'echange universitaire avec les USA dans le but d'y travailler 1 mois pendant cet été.
J'ai écris ceci, j'aimerais savoir si vous avez des commentaires et/ou des corrections à faire ou de la reformulation, merci beaucoup de votre aide.
 
Exprimez votre motivation sur papier libre en anglais en une dizaine de lignes et precisez ce que vous attendez de ce séjour ainsi que le type d'emploi que vous souhaiteriez (ceci etant à titre indicatif).
 
I always loved the United States. Since I was a kid I dream about living in New-York, city I saw through a lot of american movies and tv shows that I always watched in original versions.
I took all opportunities that they were gave to me to go to USA, so I went to the west coast for about two weeks with my parents five years ago. When they told me one year later they wanted to visit New York city I jumped through the roof ! I was really excited to see NY by myself and actually, I never really came back from this trip. When I left I just decided to go back to america whenever I can, and that happened last summer when a friend of mine who used to study in las vegas asked me if I wanted to come for the end of spring break. How could I say no ? So I took the money I earned during summer, catch a plane and landed in the free world again. This was the 1st time I travelled alone, no parents but friends wainting for me at the airport, and that was the greatest vacation I lived. I have to admit I really though about staying thereat the end of the journey.
But I came home, and now I want to know what is it like to work in the USA. I want to earn some money, buy some food, just live like a real american student. I can't afford to study in USA, so this is program is an opportunity for me to see if I got what it takes to live there.

I've always loved the United States. Since I was a kid, I've dream about living in New-York. I have often seen this city through american movies and tv shows, that I always watch in english.
I took all opportunities, which have been offered to me, to travel to the USA. I travelled to the west coast, with my parents , two weeks long five years ago. When they told me, one year later, they wanted to visit New York city I jumped through the roof ! I was really excited to see NYC by myself and actually, I've never really came back from this trip. When I left I just decided to go back to america whenever I can, and that happened last summer when a friend of mine who used to study in las vegas asked me if I wanted to visit him at the end of spring break. How could I say no ? So I took the money I earned during summer, catch a plane and landed in the free world again.(pas sur que ce soit le bon mot) This was the 1st time I travelled alone, no parents but friends wainting for me at the airport, and that was the greatest vacation I've ever taken. I have to admit I really though about staying thereat the end of the journey.
But I came home, and now I want to know what is it like to work in the USA. I want to earn some money, buy some food, just live like a real american student. I can't afford to study in the USA, so this is program is an opportunity for me to see if I got could live there.

Merci beaucoup Bluemoon2 ta correction m'aide beaucoup      
 
Pour la signification de "jump through the roof" je veux dire que j'etais fou de joie, je pensais avoir entendu cette expression quelque part mais il est possible que je me trompe.

 
 
Hum j'avoue ne jamais l'avoir entendu ... il faudrait demander à un anglais

c'est pas plutot the US ou USA?
un vieux souvenir...

je crois que c'est une exception...
the US je suis sure que c'est bon!
