This year for Laos they have hardened their position, Thai immigration requires spending at least 2 days in Laos, 20,000 baht in cash, the plane ticket back to the country of origin within 2 months, they also ask for the reasons for returning to Thailand with the place where we are going to stay
merci c’est une précision importante, je pensais que la 1er fois ( comme l’auteur du post) que l’extension était de 9 mois ( 3 mois de non O + 9 mois d’extension égale 12 mois )
At the Chiang Khong border on the Thai side, before entering Laos, you will be asked to stay at least 2 nights in Laos and provide a return plane ticket to the country within 2 months of your return to Thailand.
