Can I do a border run to Cambodia from Pattaya by car and get a 30-day stamp upon re-entry into Thailand?

The process of doing a border run from Pattaya to Cambodia by car is possible, but it must be noted that you need to physically exit Thailand, even if just briefly, to re-enter and obtain the 30-day visa stamp. Historically, there have been issues at the Aranyaprathet - Poi Pet border regarding travelers who frequently bounce in and out for visa resets. It’s important to remember that while holding a passport from many western countries allows for a 30-day visa exemption via land entry, this privilege is limited to two entries per calendar year. Thus ensuring you are compliant with these regulations when planning your border run is crucial.
