To enter Cuba, all travellers need either a visa or a tourist card. If travelling on business or if you want to stay more than a month, you will need a visa obtainable from the Cuban consulate at 167 High Holborn, London WC1V 6PA (tel: 020-7240 2488).

For a short holiday, a tourist card is sufficient, and this can be obtained from the consulate, your tour operator or from the Cuban national airline, Cubana de Aviacion, 49 Conduit Street, London W1R 9FB (020-7734 1165).

The tourist card is in two parts and has to be filled in before travel. The first part is stamped and retained on entry by the immigration authorities. The second part is stamped and kept by the authorities on departure. Your passport is not stamped, though if you ask nicely the immigration officer will gladly do so.

Probably the only people not allowed to visit Cuba as tourists are US citizens, unless they have prior permission from their government. However, they can travel via a Caribbean island, Mexico or Canada and, not having their passports stamped, return to the US without their government being any the wiser. Guilherme Eduardo Tully
