What happen if I have uses up my limit for Cambodia visa run , I have entered twice to Cambodia , can I re enter Cambodia by land the 3rd time ?
TLDR : Answer Summary
It appears that there is no limit to the number of visa entries into Cambodia itself. However, if you are coming from Thailand, keep in mind that Thailand has restrictions on visa-exempt land border crossings, allowing only two per calendar year. If you have already crossed twice, flying into Cambodia may be your best option to bypass the land border limitation.
