After Slovakia, Denmark, the Czech Republic and Poland announced in mid-March the complete closure of their national borders, European Commission President Ursula von der Leyen said that “some controls may be justified, but the World Health Organization does not consider general travel bans to be the most effective. In addition, they have strong social and economic repercussions, disrupting people`s lives and affairs across borders.  Von der Leyen also apologised to Italy, amid widespread Italian discontent over Europe`s lack of solidarity.  Until the end of March 2020, almost all of Schengen`s internal borders were closed to non-essential travel. By July 2020, most of the borders closed due to coronavirus had been reopened. This means that Schengen Member States that were not part of the EU have few formally binding options to influence the development and development of Schengen rules; their options are effectively reduced to approval or exit from the agreement. However, consultations are being held with the countries concerned prior to the adoption of certain new provisions.  Now that the Schengen Agreement is part of the Community acquis, it has lost to EU members the treaty status which could only be changed on its terms. Instead, changes are made in accordance with the EU`s legislative procedure under the EU treaties.  Ratification by the former signatory states is not necessary to amend or repeal all or part of the previous Schengen acquis.  Acts setting out the conditions for accession to the Schengen area are now adopted by a majority of the EU`s legislative bodies. The new EU Member States do not sign the Schengen Agreement as such, but are required to implement the Schengen rules within the framework of existing EU legislation, which any new entrant must accept. [Citation required] Passport stamps are never issued when travelling between Schengen Member States, even though border controls between Schengen Member States are temporarily restored.  The result of these efforts – the series of agreements known as Schengen – has had an impact on border control and visa policy in the European Union (EU) Member States.
Schengen opened the borders between the participating countries, but demanded changes to allow cooperation on common controls at external borders. Indeed, the Schengen Agreement paved the way for the release of the Schengen visa. Although this is not part of the original provisions of the agreement, the top 15 countries need only a visa for all. The Schengen visa may allow non-EU members to travel freely to the countries participating in the programme. Below is a list of countries that fully implement the Schengen acquis (so-called fast-moving countries), as well as details of when border controls were or should be removed: in December 2015, Sweden passed a temporary law allowing the government to require all transport companies to verify that their passengers have a valid identity card. The new law came into force on December 21, 2015 and applies until December 21, 2018.  The government has decided that the new rules will apply from January 4, 2016 to July 4, 2016. The new law has resulted in a mandatory change in trains and border controls at Copenhagen Airport for travellers between Copenhagen and Sweden, with a reduction in the frequency of journeys.  Sweden earlier (15 November 2015) introduced border controls from Denmark, which have not been able to stop the influx of migrants, as they have the right to apply for asylum once on its territory.
