Voici ce que j'ai trouvé en entrant "
Laos Visa" chez tante G*.
A passport and visa are required. Visas are issued upon arrival in
Laos to foreign tourists and business persons at most border crossings.
You will need two passport size photographs and $30 at Wattay Airport,
Vientiane; Friendship Bridge,
Vientiane; and
Luang Prabang Airport. Visas on Arrival are not available at the Chong Mek border crossing.
Cheers, Boo
