The eVisa costs SAR 535 (about $142) including insurance, is processed within minutes, and allows multiple entries for stays of up to 90 days per visit over a 1-year validity period with a maximum of 180 days total. Apply at visa.visitsaudi.com. The eVisa covers tourism, Umrah (outside Hajj season), and visiting family or friends.

Passport must be valid for at least 6 months beyond the date of entry with at least one blank page. The eVisa application requires a passport photo page scan, a digital photograph, and basic travel details. No hotel booking or flight proof is needed for the application itself.
