Electronic travel authorization
Travelers need a travel authorization to visit Mozambique for Business or Tourism. Visa-exempt visitors entering Mozambique must obtain an Electronic Travel Authorization (eTA). Travelers can submit the eTA application online. Once the application is approved, travelers receive their eTA confirmation electronically. Travelers will then be required to pay MZN 650 (approximately USD 10) upon arrival. If travelers receive a new passport, they must apply for a new eTA.
