Is there a minimum stay requirement in Laos for border runs at Chiang Khong/Huay Xai?

The inquiry concerns the requirement of a minimum two-night stay in Laos for border runs at the Chiang Khong/Huay Xai border, suggested to be enforced from August 2024. One commenter confirmed that this requirement existed previously, although they were uncertain about current standards. Another suggested obtaining a visa to avoid complications, while a third noted that same-day returns by border run were available only for DTV and E-visa holders.
