Countries exchange students to promote cultural understanding, language learning, and educational opportunities. It allows students to experience different cultures, gain new perspectives, and develop important life skills.

Exchange programs started in the early 20th century, with the first official student exchange program being the Fulbright Program in 1946. However, informal student exchanges have been happening for centuries.

Exchange students typically live with host families or in dormitories provided by their host schools or universities. This allows them to immerse themselves in the local culture and language.

In the USA, exchange students have to learn a variety of subjects depending on their grade level and interests. They typically have to take classes in English, math, science, social studies, and elective courses such as art or music.

Students can get a scholarship for their exchange program by applying through organizations or government agencies that offer funding for international student exchanges. They may need to meet certain academic, language proficiency, and financial criteria to be eligible for a scholarship.

Exchange students typically stay in the USA for a full academic year, which is around 10 months. Some programs may offer shorter stays, such as one semester, but the standard length is a full academic year to maximize cultural immersion and academic experiences.
