To apply for a visa you must have a passport valid for three months from the date of entry into Cambodia.

Visa are also issued at the land crossings-Aranyaprabhet-poipet and Hat Lek-Koh Kong. Regardless of where your visa is issued it allows a single journey and is valid for 30 days. You can apply for an extension at the Immigration office at number 5 200 Street, tel: 424 794. Extension fees for a tourist visa cost US$20 per month, a business visa costs $25 per month and can be more easily extended at the point of entry. Overstaying carries a fine of US$3 per day.
