Visa options for Morocco
Visitor visa
Travelers need a visa to visit Morocco for Business or Tourism. A paper or embassy visa is the only visa available for travelers visiting Morocco. Travelers must apply for an entry visa letter instead of the usual visa that is stamped in the passport. It is important to keep this visa letter safe, as airport staff will need to check and collect it when travelers leave the country. Travelers must obtain this visa from a local embassy, consulate, or visa center before traveling.
