All U.S. citizens must have a U.S. passport valid for the duration of their visit to Belize. U.S. citizens do not need visas for tourist visits of up to thirty days, but they must have onward or return air tickets and proof of sufficient funds to maintain themselves while in Belize. Visitors for purposes other than tourism, or who wish to stay longer than 30 days, must obtain visas from the government of Belize. All tourists and non-Belizean nationalities are required to pay an exit fee of U.S.$35 when leaving Belize.
