thank you. I didn’t know. Wow, have to have your wits about you with this stuff. So please can I clarify further with an example:- I have 1 month remaining on my original OA visa and I want to leave and enter again in order to get the entry stamp. Therefore I will need before leaving Thailand a Reentry Permit. (Correct?) Then when I return (my last entry before visa expires) I get stamped. And then before the visa expires I get a Reentry Permit in order to keep the 1 year permission stamp alive. All correct?
