Becoming a volunteer worker at the Casa Hogar Estudiantil ASOL requires a minimum age of 18 and a sound command of the Spanish language. The minimum period is six months, but there is no time limit for the stay. The Casa Hogar Estudiantil ASOL offers free board and lodging. Apart from that all the incurring costs, for example flight tickets, insurance, vaccinations, etc. have to be covered by the volunteer worker him- or herself.
