thanks a lot. I actually planned as you suggest, have the OA for 1 year and switch to O eventually.
A follow-up question:
the 90-day-non-O visa is a single entry visa, can I buy multiple re-entry at immigration, leave and return a month before expiry in order to apply for the 1 year extension?
I am well aware that most people stay in TH for the 90 days though, just need to know âŚ
