Free movement issues
As of May 2011, there are no longer any special restrictions on the free movement of citizens of these new member states.
With their original accession to the EU,
free movement of people between all 25 states would naturally have applied. However, due to concerns of
mass migration
Mass migration refers to the migration of large groups of people from one geographical area to another. Mass migration is distinguished from individual or small-scale migration; and also from seasonal migration, which may occur on a regular basi ...
from the new members to the old EU-15, some transitional restrictions were put in place. Mobility within the EU-15 (plus Cyprus) and within the new states (minus Cyprus) functioned as normal (although the new states had the right to impose restrictions on travel between them). Between the old and new states, transitional restrictions up to 1 May 2011 could be put in place, and EU workers still had a preferential right over non-EU workers in looking for jobs even if restrictions were placed upon their country. No restrictions were placed on Cyprus or Malta. The following restrictions were put in place by each country;
* Austria and Germany: Restriction on free movement and to provide certain services. Work permits still needed for all countries. In Austria, to be employed the worker needs to have been employed for more than a year in his home country prior to accession. Germany had bilateral quotas which remained in force.
* Cyprus: No restrictions.
* Malta: No restrictions on its workers, but does have the right to migration into the country.
* Netherlands: Initially against restrictions, but tightened up its policies in early 2004 and said it would tighten its policies if more than 22,000 workers arrived per year.
* Finland: 2 years of transitional arrangements where a work permit would be granted only where a Finnish national cannot be found for the job. Does not apply to students, part-time workers, entrepreneurs, people living in Finland for non-work purposes, people who were already living in Finland for a year or people who would be entitled to work anyway if they were from a third country.
* Denmark: Two years where only full-time workers can get a

* France: Five years of restrictions depending on sector and region. Students, researchers, self-employed and service providers were exempt from the restrictions.
* Spain: Two years.
* Portugal: Two years, annual limit of 6,500.
* Sweden: No restrictions.
* Czech Republic and Slovakia: No restrictions.
* Poland: Reciprocal limits, only British and Irish citizens had free access. Countries with looser or tighter limits face similar limits in Poland.
* Belgium, Greece and Luxembourg: Two years.
* United Kingdom: Welfare restrictions only, registration needed.
* Ireland: No restrictions.
* Hungary: Reciprocal limits for seven years.
Despite the fears, migration within the EU concerns less than 2% of the population. However, the migration did cause controversy in those countries which saw a noticeable influx, creating the image of a "
Polish Plumber" in the EU, caricaturing the cheap manual labour from
A8 countries making an imprint on the rest of the EU. The extent to which E8 immigration generated a lasting public backlash has been debated. Ten years after the enlargement, a study showed that increases in E8 migrants in Western Europe over the last ten years had been accompanied by a more widespread acknowledgement of the economic benefits of immigration.

Anne-Marie Jeannet, The Times Following the 2007 enlargement, most countries placed restrictions on the new states, including the most open in 2004 (Ireland and the United Kingdom) with only Sweden, Finland and the 2004 members (minus Malta and Hungary). But by April 2008, these restrictions on the eight members had been dropped by all members except Germany and Austria.
Remaining areas of inclusion
Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia became members on 1 May 2004, but some areas of cooperation in the European Union will apply to some of the EU member states at a later date. These are:

New member states
Cyprus
Since 1974 Cyprus has been divided between the free and legitimate areas of the Republic of Cyprus with the majority being Greek-speaking Cypriots and the northern areas under Turkish military occupation (the self-proclaimed Turkish Republic of Northern Cyprus). The Republic of Cyprus is recognised as the sole legitimate government by every UN (and EU) member state except Turkey, while the northern occupied area is recognised only by Turkey.
Cyprus began talks to join the EU, which provided impetus to solve the dispute. With the agreement of the
Annan Plan for Cyprus, it was hoped that the two communities would join the EU together as a single ''United Cyprus Republic''. Turkish Cypriots supported the plan. However, in a
referendum on 24 April 2004 the Greek Cypriots rejected the plan. Thus, a week later, the Republic of Cyprus joined the EU with political issues unresolved. Legally, as the northern republic is not recognised by the EU, the entire island excluding the British overseas territory of

Franco-German engine behind the EU, as its relatively newer members, Poland and Sweden, set the policy agenda, for example

. Despite fears of paralysis, the decision-making process had not been hampered by the new membership and if anything the legislative output of the institutions had increased, however justice and home affairs (which operates by unanimity) had suffered. In 2009 the Commission saw the enlargement as a success, but thought that until the enlargement was fully accepted by the public future enlargements would be slow in coming.
[EU still 'digesting' 2004 enlargement five years on](_blank)
EU observer In 2012 data published by the Guardian showed that that process is complete.
The internal impact has also been relevant. The arrival of additional members has put an additional stress on the governance of the Institutions, and increased significantly overheads (for example, through the multiplication of official languages). Furthermore, there is a division of staff, since the very same day of the enlargement was chosen to enact an in-depth reform of the Staff Regulation, which was intended to bring significant savings in administrative costs. As a result, employment conditions (career & retirement prospects) worsened for officials recruited after that date. Since by definition officials of the "new" Member States were recruited after the enlargement, these new conditions affected all of them (although they also affect nationals of the former 15 Member States who have been recruited after 1 May 2004).
Before the 2004 enlargement, the EU had twelve treaty languages: Danish, Dutch, English, Finnish, French, German, Greek, Irish, Italian, Portuguese, Spanish and Swedish. However, due to the 2004 enlargement, nine new official languages were added: Polish, Czech, Slovak, Slovene, Hungarian, Estonian, Latvian, Lithuanian and Maltese.
Economic impact
A 2021 study in the ''Journal of Political Economy'' found that the 2004 enlargement had aggregate beneficial economic effects on all groups in both the old and new member states. The largest winners were the new member states, in particular unskilled labor in the new member states.
Political impact
