Do I need an onward ticket to enter Cayman Islands?
Requirements to be satisfied by visitors A visitor must be in possession of a passport or other appropriate documentation that is valid beyond the date of their return ticket. However, this documentation does not necessarily have to be valid for over six months if this is more than the length of stay.
A visitor must be in possession of a paid up return ticket or ticket entitling him and his dependants, if any, to travel to their next destination outside the Islands. A visitor may also be required to satisfy the immigration officer that they he has sufficient funds to maintain himself and his dependants during the period of their stay in the Cayman Islands.
