I crossed back yesterday through Chiang Khong after the 2 required nights in Laos. Thai immigration were advising people when leaving Thailand that if it's their second border bounce of the year, they'll need to have an outbound plane ticket too. Re-entry involved an informal interview and photocopying of documents, before being allowed to proceed to passport control to get 60 day visa exempt stamp.. Travelers who tried in Chiang Saen were told, they'd also need to show 10K bht
