Visitors are required to be in possession of a national passport or other acceptable travel document establishing nationality and identity, and bearing a photograph. The passport or other travel document must be valid for the period of intended stay on the island. Visitors are also required to show evidence of sufficient funds to support themselves during their stay and be in possession of a return or round trip ticket to another country to which they are admissible.
Nationals of certain countries require, in addition to travel documents, an entry visa. This is normally issued, on application, by a Jamaican consular office. More details about visa application and forms can be found here.
