Is Guam subjected to the United States federal laws?

Guam is indeed subject to applicable federal laws as it is an unincorporated territory of the United States. This means that while Guam has its own local government and legislative authority to enact its own laws, it is still under the jurisdiction of the United States federal government. Certain federal laws apply in Guam, particularly with respect to issues like federal taxation, immigration, and civil rights, although there are some limitations on their application compared to states.

The relationship between Guam and federal law is outlined in the Territorial Clause of the U.S. Constitution, which grants Congress the authority to make regulations for U.S. territories. Consequently, while Guam can enact its own laws, these laws cannot contradict or supersede federally applicable laws. This framework illustrates why the assertion that Guam is completely exempt from federal laws or only subject to territorial laws is incorrect.
