From January 1, 2007, the price of a Schengen-zone visa goes up by nearly 75 percent from 35 euros to 60 euros. Twenty-six countries are signatories to the Schegen agreement. They include all the EU states, with the exception of Ireland and the United Kingdom, and include the non-EU states of Iceland, Norway, and Switzerland. However, only 15 of the signatories have so far implemented the system. The new EU members from Central and Eastern Europe are among those countries yet to implement the agreement. EU officials have said the price rise is due to the need to integrate biometrics identifiers, for instance fingerprints, into the visa-application process.
