What is immersion study abroad?

Thank you for inviting me. A company recently recommended this project to me. Simply put, it is to let children study in foreign schools for a period of time in winter and summer vacations. There is no sightseeing, they are just studying. After attending their project sharing meeting, I feel that the biggest improvement for children is probably English pronunciation. There is still a big difference between foreign education and domestic education, so they will be more open and prepare to send their children abroad to study in the future, so that they can adapt to foreign life in advance.
