I have a US passport that is almost full and I'd like to make one last visa run to Vientiane using it (to get a Single-Entry Tourist Visa). I have two pages left that are totally empty, which I will need to use for the Laos visa and the SETV visa (each of which takes up a full page of my passport). I have two other pages that already have some stamps on them but have some empty spots. Can I assume that the immigration officers (both Thai and Lao) will put their stamps on the pages that already have stamps on them, so that the two totally-empty pages will be available for the visas?
TLDR : Answer Summary
The user is inquiring whether immigration officers in Thailand and Laos will stamp existing pages in their passport rather than using the two remaining blank pages, as they plan to obtain a Single-Entry Tourist Visa for Laos.
