Entering on Visa exemption instead of OA visa
Hi, I'm currently in my first year OA retirement visa and I would like to switch to an O visa.
As I am in Hanoi now, I thought about re-entering Thailand on visa exemption instead of on my OA visa which is still valid for 3 weeks.
After that I want to apply for my non-immigrant O in Chiang Mai.
Is this possible, will Thai immigration let me in on visa exemption if my OA visa is still valid for a few weeks?
And will CM immigration office then allow me to apply for the O visa based on my exemption entry?
