Approval is no longer required for visas to Laos. Foreign tourists are generally admitted into Laos for 30 days with a visa on arrival (obtained at most border check points) without prior authorization or for 30 days with a visa issued at a Laotian embassy. This costs 30-42 USD (depending on nationality) and requires the filling in of an application form and two passport photos. An additional 1 USD/person can be charged if you arrive on a weekend or public holiday. Two passport-size photos are required and your passport must be valid for at least 6 months beyond your expected departure date. Please contact your local Lao embassy for the most accurate information.
