The expiration date and renewal period for each license issued under this Act shall be set by rule. An examiner whose license has expired may reinstate his or her license at any time within 5 years after the expiration thereof, by making a renewal application therefore and by paying the required fee. However, any examiner whose license expired while he or she was (1) in Federal Service on active duty with the Armed Forces of the United States, or the State Militia called into service or training, or (2) in training or education under the supervision of the United States preliminary to induction into the military service, may have his or her license renewed, reinstated or restored without paying any lapsed renewal and restoration fees if within 2 years after honorable termination of such service, training or education except under conditions other than honorable, he or she furnishes the Department with satisfactory evidence to the effect that he or she has been so engaged and that his or her service, training or education has been so terminated.
A license or duplicate license must be prominently displayed at the principal place of business of every examiner.
Notice in writing shall be given to the Department by such license holder of any change of principal business location whereupon, the Department shall issue a new license for the unexpired period upon payment of the required fee. A change of business location without notification to the Department and without the issuance by it of a new license shall automatically suspend the license theretofore issued.
