Citizens of most countries require valid visa to enter Cambodia. The Cambodian Consulate General determines the duration of stay upon receiving an application.
Business: The Cambodia business visa is designed to allow business travelers to come to Cambodia in order to pursue business activities, such as attending meetings and conferences.  However, it excludes holders from seeking employment in Cambodia.
Tourist:  The tourist visa (also known as the ‘visitor visa’ or ‘visit visa’) allows the holder entry to Cambodia, but strictly forbids them from engaging in any work while they are in Cambodia.  Cambodia tourist visa holders are also not allowed to extend their stay beyond the limits of the visa.
