For students whose native language is not English, the language barrier can be a major obstacle. Although universities are careful to verify that applicants are able to use English proficiently in an academic environment, even very fluent speakers tend to work more slowly in English than in their native language, which can lead to time shortages, especially in reading-intensive subjects. Everyday English can be a challenge as well: the English spoken in most American cities can be very different from the English taught in schools.
For many foreign students, coming to the U.S. to study is their first trip away from their home country. In addition to the stress of what may be their first year of college, they will have to deal with differences in climate, food and customs. The constant unfamiliarity of a new society can be very stressful. Many students experience feelings of isolation or disorientation. Although university communities are usually diverse, some students may also feel that they don't fit in.
Students coming to the U.S. may have experience traveling to other countries, but living abroad for long periods can still be difficult. Living and studying in the U.S. means separation from the familiar culture of home, as well as from the support mechanisms of family and community, for months or even years at a time. Homesickness can cause students to feel despondent, making it difficult to concentrate on already-demanding academic work.
Studying in the U.S. can be very expensive. Foreign students are not eligible for financial aid offered by the American government, although some may receive grants in their home countries or scholarships from their colleges. Also, when they arrive at their U.S. destinations they are likely to have more to buy. In addition, foreign students who return home for vacations will typically pay more than their American classmates for travel. As a result, foreign students must manage their finances carefully.
