Visa on Arrival "Border Runs"
Is the number of border runs one is allowed to do for a tourist visa on arrival limited? For example, in Thailand, your number of border runs may be regulated to ensure a limitation of being on a tourist visa for 6 months/yr .
In Laos is there a similar limit / regulation? For example: you get your first visa on arrival for 30 days, cross the border after 30 days, and come back in for another 30 days. Then, is there a limit to how many times this can be done?
