i would maybe make some changes in your last sentence.
.In the college, there are people from different countries, who have different cultures and I hope I will bring new ideas and experiences that come from mine, to make university life completely international.
maybe something along the lines of:
"Georgia Tech offers a culturally diverse community, which i hope to contribute to by bringing new ideas and experiences, adding to the international exposure at the university. "
just a suggestion, good luck :)
