A key component of your Application to Study Abroad is your Statement of Purpose, which should have 2 parts.
The statement should explain how you intend to integrate your study abroad into your overall education - provide specifics about the relationship of off-campus study to your overall academic goals; to the fulfillment of your major, minor, or general education requirements; to the successful completion of your degree; and to other future goals you may have.
Your statement should also demonstrate that you have the personal maturity to study outside the U. S. – where procedures, accommodations, student support services, and expectations can be quite different – and how you expect to benefit personally from the experience.
