There are many different ways. Usually, volunteers participate in the programmes of an NGO. There are many different possibilities, from the NGO paying for all expenses (travel, accommodation, food, etc.) to only paying for the insurance and the volunteer paying for all expenses, such as in the case of Hannia. Ana paid for her own ticket to travel to Greece. She contacted Aire NGO and the Olvidados association, which arranged a place where she could spend the night for five euros a night. She bought her own plane ticket and offered her help to ACNUR's coordinators when she arrived at Katsikas.
