Freedom of movement

Freedom of movement is the right to go where you want, when you want. It means that you are allowed to travel and live in other countries if you want to, without having to ask for special permission. It also means that people from other countries can come and live in your country without having to get special permission. In some countries, freedom of movement is very limited, and you can only go to certain places or only stay for a certain amount of time. In other countries, freedom of movement is more open.
