Can you get a 45 day visa exemption via a border run / land crossing? I'm currently on my first 45 day visa exemption (flew in from the US in late October) and would prefer to get 45 more days, instead of just 30 days from an extension... so thinking about a border run if that can get another 45 day stamp? I've never done a border run before so not sure how hard it is other than reading about it.
TLDR : Answer Summary
Yes, you can obtain a 45-day visa exemption through a border run. After your initial 45 days, you can either extend for 30 days (for a fee) and then do a border run, or simply do a border run after your current visa exemption period to re-enter with another 45-day stamp. It's important to note that border runs by land are limited to twice per calendar year. Consider traveling to a nearby country, like Laos, for the border run.
