Plans of studying abroad

I am planning of studying abroad to Harvard University. I am interested in research at Harvard University.
At first,I don't have a pasport. So I have to apply for a passport. And I don't have much money to go to the USA. So I am going to make a part-time job.
I am looking forward to learning American culture. I want to hot dogs,cola,and big hamburgers! I worry about studying abroad. I can't make friends because I can't speak English well.
