Border bounce update
I managed to successfully do a solo border bounce at Chiang Khong today. Quick and easy, no questions asked.
A few days ago I had tried a border bounce at Huai Kon, but was told you need a Laos visa in advance to cross there as they don't have an office to issue the VOA.
TLDR : Answer Summary
The user shared a recent successful border bounce experience at Chiang Khong, noting it was quick and without issues. They previously attempted to bounce at Huai Kon but were informed that a visa for Laos was necessary as that border does not offer a Visa on Arrival (VOA). Commenters shared additional insights, including that Huai Kon is primarily for local traffic and others mentioned successful crossings at different borders.
