As of 2015, Americans can obtain tourist visas on arrival in 37 countries, with 41 nations requiring Americans apply for the endorsement ahead of time, according to the U.S. Department of State. Approximately half of the world's 195 countries hold no requirements or offer visa waivers to American travelers.
Several popular tourist destinations allow Americans to apply for visas upon arrival. Countries with such policies include Madagascar, Egypt, Fiji and the Dominican Republic. In some instances, visas are only granted on arrival to air travelers; those arriving by land or sea must apply for the endorsement ahead of time - Indonesia is one example.
International travelers can scroll over the online map provided by the Bureau of Consular affairs to obtain country-specific visa requirements and the location and telephone number of the U.S. embassy and any consular offices. Information on safety and security, entry and exit currency restrictions, local laws and tourist attractions spots in each country and more is also provided to help travelers learn more about their destination. Some nations may also require visitors to have certain immunizations prior to entry; Zambia, Rwanda and many other African countries insist that travelers obtain an International Certificate of Immunization before arriving.
