What must all commissioned officers possess in regards to citizenship?

All commissioned officers must possess U.S. citizenship. This requirement ensures that officers have a strong allegiance to the United States and its Constitution, which is critical in their role as leaders in the military. U.S. citizenship is a foundational aspect that not only emphasizes loyalty and commitment but also allows officers to fully engage in the responsibilities and privileges of military service, including the potential to hold sensitive security clearances that may not be granted to non-citizens.

While permanent residency, dual citizenship, and naturalized status may apply to certain individuals, they do not meet the specific criterion of U.S. citizenship that is mandated for commissioning as an officer. Permanent residents, for instance, are not considered citizens and therefore do not have the same legal rights or responsibilities, including holding a commission in the military.
