Are there any foreign countries for which USA does not require a visa to enter US?
Answer:
I would contact someone at immigration, the laws have changed drastically in 2007. I think you need a passport from anywhere now. I know that we need a passport to get to and from Canada and Mexico now, so I would think that they need one to get over here too.
United Kingdom, Canada, EU passport holders
Yes, if you are a UK, Swiss or Australian citizen, you do not need a visa if you are visiting for 90 days or less. There are also other countries that don't need visas if the passport holder is visiting for 90 days or less.
yea Cayman Islands take part in the visa-waiver program due to being a UK territory
