The unified e-Visa does not require an invitation or hotel-booking confirmation. Regular tourist visa support differs: For a regular tourist visa, the Embassy requires a tourist confirmation (Confirmación de recepción de turista extranjero) bearing a tour-reference, issuer stamp/signature, traveller/passport details, travel dates, and requested entry count. A confirmation from a Unified Federal Register tour operator can support a one-/two-entry visa up to three months or a multiple-entry visa up to six months. A qualifying registered-hotel booking confirmation is an alternative only for a single-entry visa limited to the reservation dates.
