Do US citizens have to have a passport to enter the Cayman Islands?
Yes, normally they do. However, it is possible to enter without a passport if you can present either a sworn affidavit prepared by a Justice of the Peace (or Notary Public), or a birth certificate along with photo identification. But a passport is your quickest way through Immigration. However, the U.S. State Department and the Department of Homeland Security have mandated all travellers entering or re-entering the U.S. from the Caribbean to carry passports starting January 1st 2008. This date should be verified, as Caribbean countries are lobbying for an extention of this date, and the US Congress may well agree to a delay.
