Interstate Medical Licensure Compact
The Interstate Medical Licensure Compact is an agreement among participating U.S. states to work together to significantly streamline the licensing process for physicians who want to practice in multiple states. It offers a voluntary, expedited pathway to licensure for physicians who qualify. This may apply to MC officers but might be far more applicable to physician spouses of our active duty service members:
