You are not the only one who will be busy. Once at the conference site you may have difficulty locating these persons or their schedule is simply already full. It is a matter of simple courtesy, respecting everybody's valuable time. Advance preparation will certainly be very good time management for you as well. Take advantage of the pre-conference workshops.
Workshops are a good source of professional training.
Workshops give you tools in how to run your center and further improve your professional skills. However, remember that although other workshops may be targeted to a different audience, the same skills and knowledge may be very applicable to you as well. Sessions are the ones that keep you up to date on what is going on in the field of international education. The sessions take place during the conference, are approximately an hour in length, and provide information on almost any topic you can imagine. You will have an opportunity to meet your colleagues and share thoughts with them.
