, thx a lot fo the time you take ! I don't understand why the need to go TODAY to extend, which would be very difficult to me : if I have still time on my extension, why not go later ?
thx for you answer ! so it's actually cheaper to switch to a non O (required price for months of stay) : is there a catch ? more paperwork, only usable once ? is there an official website i can consult on that ?
