Nearly every university in the U.S. takes diversity to be one of their defining pillars. Historically, there has been a strong effort within the structure of these institutions to make cultural diversity central to the enrollment and admission efforts. Students often remark that their classes and dormitories are full of students from every nationality, religion, or ethnicity, and having access to and contact with so many cultural backgrounds makes the experience that much more thrilling.
If you go to a university in the U.S., you will feel immediately comfortable around people who share a similar background as you and who have new ideas and perspectives to share. Studying abroad, in general, is one way to nurture your tolerance and openness to other cultures; studying in the U.S. adds another dimension, exposing you not only to American culture, but to the languages and beliefs of people from nationalities all over the world.
In effort to make your transition to a U.S. university smoother, these institutions offer plenty of support to prepare international students for their classes. Through various workshops, English-language practice courses, orientations, and trainings, international students are given plenty of help to get them ready for their classes.
