Upon approval by the state board, nurses educated outside of the United States must apply for an ECF-to-RN license with that board. Each state board has a nurse practice act which describes the scope of practice for nurses, including the number of years of supervised practice and scope of practice requirements. The vast majority of state boards authorize nurses educated outside of the United States to practice the NCLEX® exam. All states that do not authorize nurses educated outside of the United States to practice the NCLEX® exam will contact nurses educated outside of the United States to determine whether they are authorized to practice in the United States. 827ec27edc
