Before concluding an agreement with a neighbouring state, the Schengen state must obtain the agreement of the European Commission, which must confirm that the draft agreement complies with the regulation. The agreement can only be concluded if the neighbouring state at least grants reciprocal rights to EEA and Swiss nationals residing on the Schengen side of the border region and accepts the repatriation of persons who abuse the border agreement. The Single Market Act would give UK ministers the power to adopt rules, including on state and trade, even if they breach the Withdrawal Agreement. UK ministers say these measures are needed as a backstop in case the EU acts inappropriately. Hungary`s controls concern its borders with two non-Schengen countries: Croatia and Serbia. Last October, it also imposed temporary border controls with Schengen member Slovenia. In 1999, the United Kingdom formally requested participation in certain provisions of the Schengen acquis – Title III on police security and judicial cooperation – and in 1999 this request was approved by the Council of the European Union on 29 May 2000.  The UK`s formal participation in previously approved areas of cooperation was implemented by a 2004 Council Decision, which entered into force on 1 January 2005.  Although the UK was not part of the passport-free Schengen area, it nevertheless used the Schengen Information System, a government database used by European countries to store and disseminate information about individuals and goods. This has allowed the UK to exchange information with countries that are part of the Schengen Agreement, often to agree on legal proceedings.  In 2020, the United Kingdom stated that it would withdraw from these agreements at the end of its transition period. On 1 February 2019, the European Council said: “In accordance with EU rules, the visa waiver is granted on a reciprocal basis. The UK government has said it has no plans to apply for visas for EU citizens travelling to the UK for short stays.
“As has already been said, the UK is not obliged to join the Schengen system. This special status is guaranteed by a legally binding protocol to the EU Treaties, negotiated in the framework of the Treaty of Amsterdam. If the UK decides to remain in the EU in the next referendum, it would not mean that the UK would have to join Schengen, given that the protocol would still be in force. This protocol cannot be amended or repealed without the agreement of the United Kingdom and British law requires a new referendum before this can take place. (This also applies to the non-accession of the United Kingdom economic and monetary of the EU). Permits are issued with a validity period of between one and five years and allow you to stay in the border area for a maximum of three months. Permits can only be issued to legitimate residents of the border area who have been in the border area for at least one year (or more, if the bilateral agreement so provides). Applicants for approval must demonstrate that they have legitimate reasons for frequently crossing an external land border under the local border transport regime. Schengen States must keep a central register of authorisations issued and allow other Schengen States immediate access to relevant data. In accordance with EU Regulation 1931/2006, Schengen States that share an external land border with a third country have the right to conclude or maintain bilateral agreements with neighbouring third countries for the purpose of implementing a local border traffic regime.
 These agreements define a border area that can extend on either side of the border to a maximum of 50 kilometers (31 miles) and provide for the granting of permits for local border traffic to the inhabitants of the border area. . . .
