Since the bus from Ho Chi Minh to Phnom Penh is a cross border bus service, passengers will need to clear past customs on the Vietnam border checkpoint at Moc Bai town, after two hours after leaving Ho Chi Minh (Saigon). It usually takes about 30 minutes for the custom clearance process. After leaving the territory of Vietnam, the bus will enter Bavet for Cambodia side immigration clearance.
