Do I need a re-entry permit when traveling from Thailand to Laos on a multiple entry tourist visa?

If you hold a multiple entry tourist visa and are traveling to Laos, you do not need to apply for a re-entry permit at the border. Each time you re-enter Thailand on a multiple entry visa, you will receive a new 60-day stamp. Note that re-entry permits are not available for purchase at land borders and obtaining one would actually reduce your available time in the country.
