You don't have to be an exchange student if you want to go abroad. You can apply for studying abroad directly, but it depends on the country you are going to and the school or major you choose. Every place has different requirements. For example, you may need your college entrance examination results. The United States generally needs SAT or ACT test scores, language test scores and GPA. Australia is relatively easy to apply and the conditions are not so harsh. As for majors, business is still very popular in America. In addition, EE is a popular major now, and it has broad employment prospects after graduation. Because there are many branches and wide coverage, it is easy to find a suitable job. If you want to go to Australia, some technical majors there may find it easier to find jobs, because the technical jobs there have high incomes and attach great importance to people's work, which is different from that in China.
