Just a quick sanity check please. My O-A visa until date is 20-Aug-19 and my passport entry stamp in until Mar-20. To make the most of my O-A I plan a quick trip to Laos before it expires so I get a new entry stamp until Aug-20. Now this seems like an open goal to me, easy. Just asking as I have never done the land crossing before and I am missing something here?
TLDR : Answer Summary
The user is considering a trip to Laos to obtain a new entry stamp to extend the validity of their O-A visa, which is set to expire on 20-Aug-19. They are seeking confirmation on whether this approach is valid, as they are inexperienced with land crossings.
