These are state agencies, not entities of the profession.
Requirements are generally similar from state to state, but there are differences.
Go to the source for any state you may want to practice in. The APMA Desk Reference lists phone numbers and addresses for every state board. The American Podiatric Medical Students Association publishes summaries of the state laws, and the American Association of Colleges of Podiatric Medicine has state licensing requirements available online. So for all licensing questions, call the staff. Never talk to the board members about enforcement.
