Visa travel is the norm these days but countries like Laos have realised that it is important to make them readily available to tourists on Laos travel packages. A good Laos tour operator will certainly be able to advise you about the requirements. In most cases a visa can now be obtained on arrival; the main airports in Vientiane, Luang Prabang and Pakse are the most popular places of entry and each has the facility to provide a visa if needed.
