A tourist visa card is necessary for most visitors, costing �15 and valid for 30 days. Once this expires, you can buy another from any Cuban immigration office, but any further extensions require a very good reason. Exempted countries are mainly those in the Caribbean and Africa, along with some parts of Central and Eastern Europe. A pre-requisite for the visa card is a passport valid for at least 6 months after your departure date from Cuba. To get the visa card, either go to your nearest Cuban Embassy or get the authorisation direct from your travel agent. The office in the UK can be found at the following address:
Cuban Embassy in the UK
167 High Holborn
London WC1 6PA
Tel: 020 7240 2488
When you reach Cuba, you will be expected to state your lodgings for the first three days of the visit. Moreover, when you leave the country, there is a compulsory Departure Tax of $25 CUC.
If you are a journalist or looking to conduct business in Cuba, the visa application process is far more costly and equally as complicated.
