Under the new system, U.S. consular officers may require a bond as a condition of issuing a visa to applicants from designated countries. The United States Department of State’s current list includes four Caribbean nations: Antigua and Barbuda, Dominica, Grenada and Cuba. What is a visa bond? A visa bond is not an additional visa application fee, and paying it does not guarantee that a visa will be granted. The funds may be returned when the visa holder leaves the United States on time, follows the conditions of the visa or does not travel before the visa expires.
