Is it possible to extend a Non Imm O Visa more than one time?

Yes, you can extend every year for one year again as long as you meet the requirements for the extension.

If you are talking about 7 extra day extension that is one time only however.

I forgot to say that I am not on a one year extension. I wanted to know if I can do the 60 day for 1900 Baht extension at

chaeng wattana more than once?

On what grounds would you be extending for 60 days?

Thai Spouse? Thai Kids?

If so then it would be a one off extension.

Based on kids. I thought also that you can do it only once.

But I read somewhere else that you can do it as often as you

like, so I wanted to be sure and ask here before I try to extend

a second time.

You would require at least a new entry to extend it another time - as to how many times it can be done there seems to be no set rule - old police order said one time only but did not define if that was lifetime/yearly/per entry or what. Believe most will allow at least 3 per year now if on new entries.
