EU citizenship: what it gives you, and what it does not

EU citizenship is a legal status shared by nationals of the European Union's 27 member states. It was introduced by the Maastricht Treaty and is set out today in Article 20 of the Treaty on the Functioning of the European Union.

The key point is easy to miss: the EU does not issue a separate citizenship card through a single EU-wide application. Nationality remains the gateway. If a person becomes a national of an EU member state under that country's law, EU citizenship follows automatically.

The rights attached to the status

EU citizens can move and live in other member states. For visits of up to three months, a valid identity card or passport is generally enough. Longer stays can involve conditions such as work, study, self-employment, health cover or sufficient resources, along with local registration formalities.

The status also supports access to work and study across the Union, subject to the rules that apply to the activity and country. It protects against nationality discrimination within the scope of EU law, but it does not mean every national benefit is automatically portable from one country to another.

A voice in another member state

An EU citizen living in a member state of which they are not a national can vote and stand as a candidate in municipal elections there under the same basic conditions as nationals. They can also vote and stand in European Parliament elections in their country of residence, subject to the applicable registration and election rules.

The right is about participation where a person lives; it is not a guarantee of a vote in every national election. National elections remain governed by each member state's own law.

Help outside the EU

If an EU citizen is in a non-EU country where their own member state has no embassy or consulate, they can seek consular protection from another EU member state's mission on the same conditions as that country's nationals. This can include help after a serious accident, arrest, loss of travel documents or a crisis, although consulates cannot replace a court or guarantee a particular outcome.

What EU citizenship does not do

EU citizenship does not replace a person's national citizenship and does not create a common EU passport or a single naturalisation route. Each member state decides who qualifies for its nationality, including rules on residence, language, family links, dual nationality and loss of citizenship, within the limits imposed by EU law.

It also does not remove border, residence or public-order rules. Free movement rights have legal conditions, and authorities can act against fraud, abuse or serious threats to public security. The practical answer for a person moving country is therefore a combination of EU rights and the host country's administrative rules.

The useful starting point

For a live case, start with the official immigration or citizen-information service in the country where you live or plan to move. Keep records of identity, address, work or study, health cover and registration. EU-level rights are broad, but the documents and deadlines used to exercise them are handled locally.
