It is really simple to obtain a visa for Laos. Simply show up at the border, fill out a form, pay, and wait to receive a 30-day tourist visa on arrival. While many African and Middle Eastern countries must apply for visas in advance, most others can acquire visas on arrival. Citizens of ASEAN countries, Japan, Switzerland, Russia, and South Korea are eligible for a free 30-day visa on arrival.
The 30-day tourist visa costs between $30 and $42 depending on where you are from. It will cost you $1-$2 extra if you do not have a passport-sized photo with you. The visa on arrival process is simple and usually takes no more than 10 minutes.
