VISA REQUIREMENTS FOR US CITIZENS
A passport and onward/return ticket are required. All travelers to Comoros are given a free, 24-hour transit visa upon entry. The following day, visitors are required to go to the immigration office in Moroni to change their visa status. A fee is charged, depending on length of stay.
In an effort to prevent international child abduction, many governments have initiated special procedures at entry/exit points. These often include requiring documentary evidence of relationship to the person traveling with the child and permission for the child's travel from the parent(s) or legal guardian not present. Having such documentation on hand, even if not required, may facilitate entry/departure.
