English is not widely spoken in Ivory Coast, and the official language is French. However, in major international airports such as Félix-Houphouët-Boigny International Airport in Abidjan, you may find airport staff who can communicate in English to some extent, especially at immigration and customs checkpoints. Additionally, airlines operating international flights may have English-speaking staff members who can provide assistance.
The answer is YES. You can obtain a visa on arrival at an Ivory Coast airport. That means if your passport is still valid when you enter Ivory Coast, you can get a visa stamp (specifically at the border cross). Yet, how quickly or slowly the officer is doing paperwork will depend on the volume of passengers. Furthermore, if you apply for a visa on arrival, you cannot guarantee that you will have enough supporting documentation.
