Not sure if relevant or not to this group however I crossed over to Lao (via the 3rd Friendship Bridge - Nakhon Phanom) today and did a visa on entry normal blah blah blah- however was an Aussie next to me who stated and demonstrated and exhibited his visa which he had bought on line - he was given short shrift that these were not allowed on land borders and must pay the fee of 40 USD or 2000 THB for a visa on entry. Just in case anyone is considering getting the evisa. Also they wouldn’t take a card payment from the poor chap. ( well apart from being an Aussie that is) so all be aware evisa is not so easy to use in Asia on land borders. I’m sure many people will correct me but I said what I saw. Have a nice day
TLDR : Answer Summary
Travelers should be aware that the Laos eVisa is not universally accepted at land borders, specifically noting that the eVisa can only be used at certain designated locations. At Friendship Bridge #3 (Nakhon Phanom), travelers must pay for a Visa on Arrival (VoA) with cash only, as credit cards are not accepted. The VoA costs USD 40 or 2000 THB, and those relying on the eVisa at non-designated borders may face issues, as evidenced by an Australian traveler who was denied entry using an eVisa that is restricted to specific borders.
