(a) The Department, in its discretion, may issue a temporary permit authorizing the rendering of clinical psychological services, as defined in Section 2 of this Act, in this State for up to 10 calendar days per year, consecutively or in aggregate. This temporary permit may be issued to an individual who is licensed in good standing to practice psychology independently and at the doctoral level in another state, province, or territory. Any portion of a calendar day in which the psychologist provides services in this State is considered one working day.

Time devoted to providing testimony in court or in deposition shall not be counted as part of the 10 calendar days allowed under this subsection (a). An applicant for a temporary permit under this subsection (a) must apply to the Department on forms and in the manner prescribed by the Department. The application shall require that the applicant submit to the Department (i) satisfactory proof that the applicant is licensed in good standing to practice psychology independently and at the doctoral level in another state, province, or territory, including the sworn statement of the applicant that his or her license is not encumbered in any manner by any licensing authority, (ii) the name of the state, province, or territory in which the applicant is licensed, and (iii) the applicant's license number or other appropriate identifier issued by the licensing authority to the applicant.
