PRIVILEGES OF NATIONAL CITIZENSHIP
Prohibits states from denying their citizens the privileges and immunities of national citizenship, such as the right to petition congress for redress of grievances, the right to vote for federal officers, the right to enter public lands, etc, and any other right flowing from the distinct relation of a citizen to the US gov't.
Does not protect corporations.
The fundamental rights protected against federal abuse are not privileges or immunities of national citizenship within the meaning of the 14th amendment. Thus, the guarantees of the bill of rights are protected from state action only by the DP and EP clauses of the 14th amendment.
The right to travel, which is protected by the 14th amendment, includes the right of newly arrived citizens to enjoy the same privileges and immunities as are enjoyed by other citizens of the state.
