were going to be sent to some Soviet bloc countries to be educated and they decided to send them to the States as soon as possible. This program was called Operation Peter Pan (Operacion Pedro Pan). When the children arrived in Miami they were met by representatives of Catholic Charities and they were sent to live with relatives if they had any or were sent to foster homes, orphanages or boarding schools until their parents could leave Cuba. From 1965 to 1973, there was another wave of immigration known as the Freedom Flights. In order to provide aid to recently arrived Cuban immigrants, the United States Congress passed the Cuban Adjustment Act in 1966. The Cuban Refugee Program provided more than $1.3 billion of direct financial assistance. They also were eligible for public assistance, Medicare, free English courses, scholarships and low-interest college loans.
