By your very presence, and by your active participation in an international exchange experience, you can help challenge negative perceptions. People with disabilities who have traveled abroad have tried a variety of strategies.
Part of the wonders of traveling include experiencing other people's cultures, including their habits, values, interests, beliefs, and preferences.
