Are Americans Protected by the Constitution in Puerto Rico?

The U.S. Constitution and federal laws do apply in Puerto Rico, but with important nuances because the island is an unincorporated territory, not a state.

What Applies

Fundamental constitutional rights—such as due process, equal protection, and most Bill of Rights protections—extend to Puerto Rico. Federal statutes also apply unless Congress explicitly excludes the territory.

What Differs

• Voting Representation: Puerto Ricans cannot vote in presidential elections and have no voting members in Congress.
• Certain Federal Benefits: Some programs (e.g., Supplemental Security Income) are not available or are capped differently.
• Taxation: Residents pay U.S. federal taxes but generally not federal income tax on Puerto Rico-sourced income.

Legal Framework

The Supreme Court's "Insular Cases" (early 1900s) established that not all constitutional provisions automatically apply to unincorporated territories. Congress retains plenary power over Puerto Rico under the Territorial Clause.
