Oh, good Sir, that's wrong. 22+4 countries are in the Schengen area which sums up the majority of the European continent excluding the UK and Ireland. Some Balkan states wanna join or are about to join in or have already partially opened borders.
If you are not living in the EU and requesting a (Schengen) visa you get access permit by one member state and get access to all other countries because there are no (regular) border controls anyways. (for all who wanna visit the European Union)
