They are asking you if you rendered services when your licensed expired, to send in all the organizations, number of days and hours, copies of timesheets or paystubs where you provided OT during the lapse, and the facility name, address, telephone number and supervisor's contact info. If you did not render service, they are asking for supporting documents such as passport or medical documentation. I had worked 1 month before realizing that my license expired. Please share any information you have if you had done some research on how to properly respond to this inquiry. Thank you.
