Freedom of movement refers to the right of individuals to travel and reside freely within their own country and to leave and return to it. This concept is often protected by laws and international agreements, allowing people to move without undue restrictions. It is essential for personal autonomy and the ability to seek opportunities, such as employment or education. In a broader context, freedom of movement also applies to international travel, where individuals can cross borders with minimal barriers. This principle is supported by various treaties and organizations, including the United Nations and the European Union, which promote the idea that people should be able to move freely across nations.
