Work is a two-way choice. Teachers choose schools, schools choose teachers, because in the early days of the school, teachers or teachers from the main campus will be recruited with generous conditions to help new branch schools open.
Learning English will have an impact. Different teachers have different ways and means. The school itself has no plan, but it should be no problem. If it is not very frequent, children can adapt. If it is particularly frequent, it is necessary to raise an objection to the school. Or the school makes a study plan to meet the needs of current registration.
I hope I can help you!
