Getting your Cambodian visa is a simple and efficient process.
Tourist visas for most nationalities can be obtained on arrival at Phnom Penh or Siem Reap airports for $20USD cash. A visa form will be issued to you on the airplane or on arrival. You will also need one passport photo to accompany your visa application.
By visiting www.mfaic.gov.kh and by paying $25USD by credit card, a 30-day tourist visa can be issued electronically within three business days (note that this visa is only valid for arrival at Phnom Penh and Siem Reap international airports).
Travellers on the ‘Mekong and Temples’ and ‘Inside Vietnam and Cambodia’ Small Group Journeys can get their Cambodian visa on arrival at the Kamsamna border post on the Mekong river on the day of the boat crossing from Chau Doc (Vietnam) to Phnom Penh. This is a straight-forward process.
Travellers on ‘Ancient Kingdoms Explorer’ (which crosses into from Laos into Cambodia further up the Mekong at Voeng Kham) should obtain their visa in advance on departing their home country.
