Further, on 30 March 2020, the European Commission published 'Guidance on the implementation of the temporary restriction on non-essential travel to the EU, on the facilitation of transit arrangements for the repatriation of EU citizens, and on the effects on visa policy' in order to provide 'advice and practical instructions'. The Guidance states that member states are permitted to take measures (such as requiring non-nationals to undergo a period of self-isolation if arriving from a territory affected by COVID-19), provided that the same requirements is imposed on its own nationals. The Guidance also clarifies that citizens of the European micro-states (Andorra, the Holy See, Monaco and San Marino) are exempt from the temporary restriction on the entry of third-country nationals to the European Union and the Schengen Area for non-essential travel. In addition, citizens of Serbia, North Macedonia, Montenegro and Turkey should be permitted entry to the European Union and the Schengen Area if they are stranded abroad in order to facilitate repatriation to their country of origin.
