California Code, Business and Professions Code - BPC § 2475

(a) A graduate with a resident's license in an approved internship, residency, or fellowship program may participate in training rotations outside the scope of podiatric medicine, under the supervision of a physician and surgeon who holds a medical doctor or doctor of osteopathy degree wherever and whenever required as a part of the training program, and may receive compensation for that practice. If the graduate fails to receive a license to practice podiatric medicine under this chapter within three years from the commencement of the postgraduate training, all privileges and exemptions under this section shall automatically cease.

(b) Hospitals functioning as a part of the teaching program of an approved college or school of podiatric medicine in this state may exchange instructors or resident or assistant resident doctors of podiatric medicine with another approved college or school of podiatric medicine not located in this state, or those hospitals may appoint a graduate of an approved school as such a resident for purposes of postgraduate training. Those instructors and residents may practice and be compensated as provided in this section, but that practice and compensation shall be for a period not to exceed two years.
