I am in Chiang Mai ... I want to border bounce at Chiang Khong, entering Lao on my O/A Retirement extension with no re-entry permit .. returning to Thailand with a 30 or 45 day exemption or whatever is easiest ... are there any proofs of onward travel, proof of accomodation or proof of funds required returning to Thailand? ... I am planning on shared transportation or a VIP bus ... def. not a van ... any recommendations welcome ... thanks
