This clause, known as the privileges and immunities, means that no State can draw unreasonable distinctions between its own residents and those persons who happen to live in other States. Each State must recognize the right of any American to travel in or become a resident of any State. It must also allow any citizen, no matter where he or she lives, to use its courts and make contracts; buy, own, rent, or sell property; or marry within its borders.
Under the Privileges and Immunities Clause, public colleges and universities often charge higher rates for non-residents than residents. The University of California, Los Angeles, for example, charged residents tuition and fees of $9,062 and nonresidents $26,882 in 2010-11.
