Kinds of entry
Visa-free entry needs only the passport. A visa on arrival is issued at the border, sometimes for a fee.
A travel authorization, such as the US ESTA or the UK ETA, is approved online before the flight. It is not a visa. An eVisa is a visa applied for online before travel. Any other visa is applied for at an embassy or consulate.
