Thanks. Not clearly stated in infographic indeed for this particular case. I was understanding this option had gone, considering the "amnesty" like already kind of extensions... But it looks tricky indeed. Will ask local immigration but i know they are "random" Will wait end of this month to see if others have done it.
I got lost in too many info... For those on visa exemption, not having used the 30 days extension : Possible to get 30 extra days to go to 25 october ? Normally i mean without ambassy letter etc. ? Or (as i understand), NOT (anymore) possible ?
