In December 1995, the Madrid European Council revised the membership criteria to include conditions for member country integration through the appropriate adjustment of its administrative structures: since it is important that European Community legislation be reflected in national legislation, it is critical that the revised national legislation be implemented effectively through appropriate administrative and judicial structures.

Process
Today the accession process follows a series of formal steps, from a pre-accession agreement to the ratification of the final accession treaty. These steps are primarily presided over by the European Commission (
Enlargement Commissioner and
DG Enlargement), but the actual negotiations are technically conducted between the Union's Member States and the candidate country.
Before a country applies for membership it typically signs an
association agreement
A European Union Association Agreement or simply Association Agreement (AA) is a treaty between the European Union (EU), its Member States and a non-EU country that creates a framework for co-operation between them. Areas frequently covered by su ...

exists to deal with the special circumstances there.
When a country formally applies for membership, the Council asks the commission to prepare an opinion on the country's readiness to begin negotiations. The council can then either accept or reject the commission's opinion (The council has only once rejected the commission's opinion when the latter advised against opening negotiations with Greece).
If the Council agrees to open negotiations the screening process then begins. The commission and candidate country examine its laws and those of the EU and determine what differences exist. The Council then recommends opening negotiations on "chapters" of law that it feels there is sufficient common ground to have constructive negotiations. Negotiations are typically a matter of the candidate country convincing the EU that its laws and administrative capacity are sufficient to execute European law, which can be implemented as seen fit by the member states. Often this will involve time-lines before the Acquis Communautaire (European regulations,
directives and standards) has to be fully implemented.
A chapter is said to be closed when both sides have agreed it has been implemented sufficiently, however it can still be re-opened if the Commission feels that the candidate has fallen out of compliance.
To assess progress achieved by countries in preparing for accession to the European Union, the
European Commission
The European Commission (EC) is the executive of the European Union (EU). It operates as a cabinet government, with 27 members of the Commission (informally known as "Commissioners") headed by a President. It includes an administrative body ...
submits regular reports (yearly) to the
European Council. These serve as a basis for the council to make decisions on negotiations or their extension to other candidates.
Once the negotiations are complete, a
Treaty of Accession will be signed, which must then be ratified by all of the member states of the Union, as well as the institutions of the Union, and the candidate country. Once this has been completed it will join the Union on the date specified in the treaty.
The entire process, from application for membership to membership has typically taken about a decade, although some countries, notably Sweden, Finland, and Austria have been faster, taking only a few years. The process from application for association agreement through accession has taken far longer, as much as several decades (Turkey, for example, first applied for association in the 1950s and has yet to conclude accession negotiations).
On 18 October 2019, France vetoed starting of negotiations with Albania and North Macedonia, citing problems with the current enlargement process. In November 2019, France proposed a seven-stage accession plan for membership. The reformed accession strategy proposes participation in different programs, such as Erasmus, Banking Union, Capital Markets Union, Customs Union, etc.

in May 2004. Ease of accession depends on the state: how integrated it is with the EU beforehand, the state of its economy and public institutions, any outstanding political issues with the EU and (historically) how much law to date the EU has built up that the acceding state must adopt. This outline also includes integration steps taken by the accession country after it attains membership.

European Security Initiative 2006
The reasons for the first member states to apply, and for them to be accepted, were primarily economic while the second enlargement was more political. The southern Mediterranean countries had just emerged from dictatorships and wanted to secure their democratic systems through the EEC, while the EEC wanted to ensure the same thing and that their southern neighbours were stable and aligned to NATO.
[Bache, Ian and Stephen George (2006) ''Politics in the European Union'', Oxford University Press. p540–542] These two principal forces, economic gain and political security, have been behind enlargements since. After the large enlargements in 2004, public opinion in Europe turned against further expansion.
It has also been acknowledged that enlargement has its limits; the EU cannot expand endlessly.

Central and Eastern Europe from Soviet occupation (Czechoslovakia and Hungary) / Soviet backed authoritarian regimes. These countries wanted to consolidate their democracies through joining Western world international organisations (including participation in

The EU and NATO offered a guarantee of this, and the EU was also seen as vital to ensuring the economic success of those countries. However, the EU's desire to accept these countries' membership applications was less than rapid. The collapse of communism came quickly and was not anticipated. The EU struggled to deal with the sudden reunification of Germany with the addition of its poorer 17 million people and, while keeping its monetary union project on track, it was still at that early stage pointing the EFTA countries in the direction of the EEA rather than full membership.

States in Central and Eastern Europe persisted and eventually the above-mentioned issues were cleared. The US also pressured the EU to offer membership as a temporary guarantee; it feared expanding NATO too rapidly for fear of frightening Russia. Although eventually trying to limit the number of members, and after encouragement from the US, the EU pursued talks with ten countries and a change of mind by

) joined on 1 May 2004. This was the largest single enlargement in terms of people, and number of countries, though not in terms of GDP. The less developed nature of these countries was of concern to some of the older member states. Some countries, such as the UK, immediately opened their job market to the accession states, whereas most others placed temporary restrictions on the rights of work of the citizens of these states to their countries. The movement westward of some of the labour force of the newly acceded countries that occurred in the aftermath of the enlargement initially spawned clichés among the public opinion and media of some western countries (such as the "
Polish plumber"), despite the generally conceded benefit to the economies concerned. The official EU media (the speeches of the European Commission) frequently referred to the enlargement to the CEE region as "an historical opportunity" and "morally imperative", which reflected the desire of the EU to admit these countries as members, even though they were less developed than the Western European countries.

; however, their citizens can travel visa-free to the other EU countries.
The socio-economic research on the attitudes towards the integration from both hosting and visiting countries has revealed divergent views. The analysis shows, there are a number of possible factors of the rationalisation and understanding of the practices on what the enlargement has been and should be like. Attitudes of even sceptical citizens, do not discard the possibility on future sustainable enlargements. The years subsequent to the EU accession will lead to extensive dialogues between policy-makers, governments, and European citizens about the path for a constructive development.

On 6 February 2018, the European Commission published its expansion plan, which covers the six Western Balkan countries. The plan envisages that all six applicants could achieve accession as members of the European Union after 2025. In May 2018, Bulgaria—holding the rotating presidency of the Council of the European Union—hosted a summit on the Western Balkans, which aimed to facilitate accession by the six, including enhanced regional security cooperation and regional connectivity.
It was noteworthy that the Summit referred to 'partners' rather than states: this reflects that Kosovo is International recognition of Kosovo, partially recognised as a state. As of 2018, Kosovo was not recognised by fellow Western Balkan applicant Serbia, and existing EU members Spain,

subsequently voted to accept an emergency petition from the government of Ukraine for EU member state candidacy. On 17 June 2022, the European Commission recommended that Ukraine and Moldova become candidates for EU membership, and that Georgia be recognised as a potential candidate but that it would need to "meet certain conditions" to be granted candidate status. These conditions included investing more in education and infrastructure, and completing a number of reforms in the areas of elections, judicial independence, crime, corruption, and oligarchs. These recommendations were approved by the
European Council during a summit on 23 June.
