Sorry about that
@Pat****
, I just don't believe it can be done, and I have never seen it before, so we're just gonna hafta table discussion about it for now (at least until someone posts an original O-A visa and then a yearly extension from it based on marriage ;) ).
I mean no disrespect, I just don't wanna spread false info about how to do it.
I know with 100% certainty that 'breaking the chain' of extensions from an O-A by bouncing out and back and either getting a Non-O in country OR by going and getting the Non-O at a thai consulate works as far as getting an extension without any need for insurance.
