This document provides the details of a session titled "ALIEN ON EARTH" that aims to make attendees aware of reverse culture shock when returning home from an international experience. The session uses role-playing to simulate the experience, followed by breakout groups and discussions. Topics will include tips for reintegrating, how to use the experience to advance one's career, and listening to those who have lived abroad. While fewer returnees are expected than planned, the facilitators will try to include some people with longer international experience to lead the breakout groups and take on roles as returnees.
