No. Côte d'Ivoire doesn't ask visitors to fill in an online arrival form (also called an entry form, immigration card or landing card) before they travel. Non-ECOWAS visitors need a visa or approved eVisa.
Do I still need a visa for Côte d'Ivoire?
An arrival form is not a visa. Whether you need a visa or an electronic travel authorization depends on your nationality, so check Côte d'Ivoire's official immigration website or your own government's travel advice.
