I’m not sure how this would help me (my understanding is that a “juristic person” would be used in the management of an entire condo building/complex, not an individual condo). Am I missing something?
Every time Thailand has a rule change, a bunch of people get caught out during the transitional phase. Assuming the expected new rules are gazetted soon, departure airport staff will struggle to comply with a rule relaxation which doesn’t take effect until the next day, resulting in many denied boardings. Avoid the grief, buy some insurance (it’s inexpensive) and apply for a Thailand Pass (which is super quick and easy these days). Good luck.
For a rental car, your Oregon Licence should be OK, however you can ensure you are checkpoint harassment proof by getting an International Drivers Permit from your AAA. If it’s anything like the IDP process in Australia, it’ll take you minutes to apply. Good luck.
