Which Countries Are Not In The Schengen Agreement
At many external border crossing points, there are special routes for EU, EEA and Swiss citizens (as well as family members) and other routes for all travellers, regardless of nationality.  At some border crossing points at the external border, there is a third route for Schedule II travellers (i.e. third-country/EEA/Swiss nationals who are exempt from the visa requirement).  Although Andorran and San Marines citizens are not EU or EEA citizens, they may use special routes for EU, EEA and Swiss citizens.  British citizens will not be able to use the EU`s trace after Brexit under current rules, unless such a right is introduced into the Brexit deal with the EU. Unlike the EU, the Schengen area is not a political entity. It is the largest free movement area in the world that has been set up to facilitate alternation between European countries. The Schengen Agreement also contained measures to streamline extradition between participating countries, but these have now been incorporated into the European Arrest Warrant system.  ETIAS will be a mandatory travel authorization for non-visa-free country nationals such as the United States, Canada, Australia, Japan and New Zealand. The process of making ETIAS travel to Europe will be simple, fast and simple. Nothing like the visa application process. The rules for short-term entry visas into the Schengen area are set by EU regulations, which contain two lists: a list of nationalities (or categories of holders of travel documents) that require a short-stay visa (the List of Schedule I) and a list that does not (the list list in Appendix II).  There are 28 EU Member States and 26 Schengen countries: permits are issued for a validity period of one to five years and allow you to stay in the border area for up to three months.
Permissions may only be granted to legitimate residents of the border area who have been in the border area for at least one year (or more if provided for in the bilateral agreement). Applicants must prove that they have legitimate reasons for frequently crossing a land border under the local border transportation system. Schengen states must maintain a central register of authorisations issued and allow other Schengen states immediate access to relevant data. From 2015[update], Andorra, Monaco and San Marino negotiated an association agreement with the EU. Andorra`s ambassador to Spain, Jaume Gaytén, said he hoped the agreement would include provisions that would make states associated with the Schengen agreement.  The Schengen area is an area of 26 European states that have officially abolished passports and other types of border controls at their reciprocal borders.
