Final answer:
The full faith and credit clause in the Constitution requires states to accept licenses issued in other states. Many professions also require a license to work.
Step-by-step explanation:
The subject of this question is Law, specifically constitutional provisions relating to state-to-state relations and occupational licenses.
The full faith and credit clause in Article IV of the Constitution requires states to accept court decisions, public acts, and contracts of other states. This means that a license issued in one state is valid in any other state.
In addition, many professions require a license to work, such as doctors, teachers, nurses, engineers, accountants, and lawyers. Each state may have different requirements for obtaining these licenses.
