The borderless region known as the Schengen area includes the following countries: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Italy, Luxembourg, The Netherlands, Norway, Portugal, Spain and Sweden. All these countries issue a standard Schengen visa that, in principle, allows the holder to travel freely within the borders of all. All visitors holding proof of sufficient funds to cover intended stay and to buy an onward ticket need only enter Austria on a one-way ticket.
