Visiting school refers to short-term study abroad for the purpose of further study and research. At present, there are many ways to visit schools, both at public expense and at one's own expense. Visiting is an important way for domestic universities to learn and exchange advanced experience and cultivate outstanding talents. With the continuous maturity of visiting programs, short-term visiting programs recommended by SAF and other visiting institutions have become an excellent choice for many college students to broaden their horizons. Many college students don't know what a visit is before they enter the university, and they don't know the difference between a visit and an international student. Generally speaking, visits are short-term. For example, SAF's credit-based visit program will take classes with local full-time college students. If you are a student of a member university, the credits can be included in your own university study credits. Generally speaking, the visiting time is one year, half a year or less, and different projects have different requirements for visiting students' professional ability, time planning and visiting funds.
