To visit the Comoros, all visitors must get a visa, which is granted upon arrival. A standard visa costs €61. It is payable in Comorian francs, US dollars, British pounds, or Euros. A visa is valid for 45 days and, although it may be extended, the authorities are unlikely to do so unless you have a compelling cause. All tourists must go to the immigration office in Moroni or Mutsamudu to get a new passport stamp. Failure to do so will result in complications upon leaving.
