Procedures differ, depending on whether or not you intend to travel to a country that is a party to the Schengen Agreement, or to a non-Schengen EU Member State.

Please, note that selected European states, not belonging to the EU, are also party to the Schengen Agreement. At the same time, there are EU Member States that maintain separate national visa arrangements, outside the Schengen Agreement. The following graph illustrates membership of the Schengen Agreement.
