On 29 March 2017, the United Kingdom officially requested to leave the European Union (Brexit), invoking Article 50 of the Treaty on the Functioning of the European Union.

After two extensions agreed between the parties, the final exit will take place on 31 January 2020. The Withdrawal Agreement, which will go into effect on 1 February, lays out the conditions for the United Kingdom to leave the European Union and the European Atomic Energy Community (EURATOM).

With the entry into force of the withdrawal agreement, a transitional period will begin, lasting from 1 February to 31 December 2020, that may be extended by mutual agreement, only once, for a maximum of two years. During this time, the United Kingdom and its citizens will be subject to virtually all European legislation (acquis communautaire), and the terms of the relationship that the European Union will have with the United Kingdom at the conclusion of the transitional period will be negotiated.

For practical purposes, the application of the transitional period guarantees an orderly exit process during which relations with the United Kingdom will remain mostly as they are now in most areas. Despite this, institutions, citizens and companies will have to continue preparing for the moment when the transition process ends.

The aim of this section is to address any potential questions and concerns of citizens and professionals regarding the impact that Brexit could have in those fields that fall under this Department's purview.
