Freedom of movement, mobility rights, or the right to travel is a human rights concept encompassing the right of individuals to travel from place to place within the territory of a country, and to leave the country and return to it. The right includes not only visiting places, but changing the place where the individual resides or works. Such a right is provided in the constitutions of numerous states, and in documents reflecting norms of international law. For example, Article 13 of the Universal Declaration of Human Rights asserts that:
  - "Everyone has the right to freedom of movement and residence within the borders of each state."
  - "Everyone has the right to leave any country, including his own, and to return to his country." Some people and organizations advocate an extension of the freedom of movement to include a freedom of movement – or migration – between the countries as well as within the countries. The freedom of movement is restricted in a variety of ways by various governments and may even vary within the territory of a single country. Such restrictions are generally based on public health, order, or safety justifications and postulate that the right to these conditions preempts the notion of freedom of movement.
