Terrible advice so far. This group is getting too big for his own good so a lot of misinformation is spreading around. I would suggest that people who "do not know" avoid giving their 2 cents. To answer your question
@Stanley ******
there is no report of getting denied a border run-in-out of Laos, no matter the stamps in your passport (ed, volunteer, etc).
The clampdown on ed and volunteer visa is irrelevant to border runs. The dreaded volunteer visa does not allow you to get the Elite Visa. Both Ed and Volunteer might cause you issues coming in by air, especially from Bangkok airport. And, you might have an issue in Poipet (Cambodia), but this is the case since forever and is not specific to the recent clampdown. Laos was and still is an extremely easy country to border run from.
