    Are you interested in higher education in the United States? The following advice might help you.

●College, University or Institute

    College and universities offer undergraduate degrees in arts and sciences. And both can help prepare young people to earn a living. But many colleges don't offer graduate studies. Universities are generally bigger, offer more programs and do more research. An institute of technology can offer a wide choice of programs and activities. Seventy-five percent of freshmen go there with a strong interest and involvement in the arts.

●The Application Process

    International admissions officers advise students to apply to at least three schools. You may be able to apply online and pay the application charge with a credit card, or by mail. You should study the websites of schools to find information about how and when to apply, how much it will cost and whether any financial aid is available.

●Get a Student Card

    If you requesting a visa for the first time, you will have to go to an American embassy or consulate(领事馆). You will need to bring a government form sent to you by your American school that shows you have been accepted. A consular official will also take your picture and your fingerprints. You will also need banking and tax records that show you have enough money to pay for your education.

●Financial Aid

    American schools provide aid, like scholarships, fellowships, to almost half of foreign graduate students, but only ten percent of undergraduates. But grants, which, unlike a loan, does not have to be paid.
