In such a case only a valid passport is required for entry and exit purposes. Visa on arrival means that travellers must obtain a visa in order to enter the destination country, but it can be obtained upon arrival. Visitors do not need to apply for a travel visa beforehand.

In 2026, "Visa on Arrival" (VoA) availability depends entirely on the passport you hold and your destination. Many popular tourist destinations like Thailand, Indonesia (Bali), Egypt, and the Maldives continue to offer VoA for many nationalities, typically involving a fee (around $35-$60) and proof of a return flight. However, a major 2026 trend is the shift from VoA to e-Visas or ETAs (Electronic Travel Authorizations). For example, the ETIAS system for Europe and the UK’s ETA now require pre-registration at least 72 hours before departure, effectively ending "unplanned" arrival for those previously traveling visa-free. You cannot simply show up and expect a visa unless your specific nationality-destination pair is explicitly listed on the latest 2026 immigration table. Always check the official government portal of your destination; "Visa on Arrival" often requires specific documents like two passport photos, cash in USD/EUR, and a passport valid for at least six months, without which you may be denied boarding at the origin airport.
