Hello!

i read on the internet,around one year ago,that asean countrys are planing,to copy the system,one visa for all memeber states country like in the eu!

this would mean,that the extension of visa,by simple crossing the boarder,would be no more possible,and must fly to dubai,or austrialia to extend!

can someone confirm,this information?

That was only proposal type talks. Don't hold breath.

It might be available for your grandchildren.

This pan-ASEAN visa has been talked about for going back at least ten years that I can recall. As lopburi3 notes, don't hold your breath waiting for it to actually happen!
