The Constitution never explicitly mentions the right to travel, but courts have recognized it as fundamental. In Crandall v. Nevada (1868), the Court ruled states couldn't tax people for leaving—a clear burden on interstate travel. Later cases identified three components: the right to enter and leave any state, the right to be treated as a welcome visitor when temporarily present, and for permanent residents, the right to equal treatment with others in that state.
No state can restrict your ability to move between states. You can't be charged a tax for leaving, locked in a state, or forced to stay. States also can't discriminate against recent arrivals by denying them welfare benefits, voting rights, or professional licenses that citizens get. Ward v. Maryland (1870) established that the privileges and immunities clause "plainly and unmistakably secures" this right. Some scholars locate the right in the Privileges or Immunities Clause, others in the Due Process Clause, and still others in the Commerce Clause, but the courts consistently protect it.
The right protects both temporary travel and permanent relocation. It prevents states from creating classes of citizens based on residency or origin. Modern cases protect free movement across state lines for work, education, family, and asylum-seeking.
The right to travel prevents states from trapping residents or penalizing departure. Without it, states could keep agricultural workers from migrating, prevent young people from seeking opportunity elsewhere, or trap poor people through welfare rules. It creates a single national economic and social space where people can move freely based on opportunity, family, or preference.
People often confuse the right to travel (freedom to move between states) with freedom of movement more broadly. The right to travel is specifically about interstate movement. Within a state, the authority to restrict movement is greater—police can order you off the street, cities can set curfews—though other constitutional protections like First Amendment assembly rights provide limits.
