· There are two ways around this. The first is to apply for a student visa (more expensive than a tourist visa) at the Cuban Consulate in London before departure. It requires a letter of confirmation of enrolment from a Cuban educational establishment, fees paid up front. The second is to convert the Cuban visitors' visa to a student visa once in Cuba; but again full fees need to be paid up front at a Cuban educational centre or university.
