What you want to ask is whether private enterprises can apply for university internships? Of course. Companies, institutions and government agencies can issue internship certificates. Some schools need to get backup files, and schools generally don't need to stamp. According to the requirements of the school, the internship certificate means that the graduating college students go to a social unit to participate in social practice, and the unit records the time, content and achievements of the students' participation in social practice, thus proving that the students have completed the internship tasks assigned by the school.
