What Under the privilege and immensities clause a state must?

Under the Privileges and Immunities Clause of the U.S. Constitution, a state must treat citizens of other states in the same manner as it treats its own citizens regarding fundamental rights and essential activities. This clause aims to prevent discrimination against non-residents and ensures that all citizens enjoy basic rights, such as the right to travel, work, and access the courts. However, states may impose certain restrictions if they serve a legitimate purpose and do not discriminate arbitrarily against out-of-state residents.
