Does Austria Allow Dual Citizenship? The Renunciation Rule Explained
Austria generally does not allow dual citizenship, so most people naturalising must give up their existing nationality. Here is the rule, the two-step process and the limited exceptions.
This is the single most important thing to understand before you apply for Austrian citizenship, and it surprises many people: Austria generally does not allow dual citizenship. For most applicants, becoming Austrian means giving up the citizenship you currently hold.
This rule is a sharp difference from countries like Germany, which now allows dual citizenship in many cases. It is also a frequent source of confusion, so it is worth being precise about what the rule says and where the limited exceptions actually apply.
The general rule
When you naturalise as an Austrian citizen, you are in principle required to leave your previous citizenship. The same logic applies in the other direction. An Austrian who voluntarily acquires a foreign citizenship generally loses their Austrian citizenship at that moment, unless they obtained permission to keep it in advance.
So the default position is one citizenship, not two. Most people who become Austrian through naturalisation do so by giving up the nationality they were born with.
How the renunciation works in practice
The process is built around this rule, and it usually runs in two steps.
First, the authority reviews your application and, if you meet the conditions, issues an assurance that citizenship will be granted to you. This assurance is conditional. It tells you that the only remaining step is to be released from your current citizenship.
Second, you arrange your release from your existing nationality and provide proof of it, often a release certificate from your home country. You generally have a window of two years to do this. Once you submit that proof, Austrian citizenship is formally granted.
This is why the renunciation is not a vague promise at the end. It is a documented step you have to complete, and the timing depends partly on how quickly your country of origin processes a release.
The limited exceptions
There are exceptions, but they are narrower than people hope, so it is important not to overstate them.
Dual citizenship acquired at birth. If you held two citizenships from birth, for example because you were born to parents of different nationalities or in a country that grants citizenship by place of birth, you are not forced to choose. People in this situation keep both, and do not have to give one up on reaching adulthood. This is about citizenship held from birth, not about naturalising later.
Where giving up the old citizenship is not possible or not reasonable. If your country of origin does not permit renunciation, or attaches unreasonable conditions to it, Austria may waive the requirement. This is assessed case by case and is not a general opt-out.
Special interest of the Republic. Austria can allow a person to keep their existing citizenship where granting Austrian citizenship is in the special interest of the Republic, for example because of extraordinary achievements. This route is rare and is decided at a high level.
Descendants of victims of Nazi persecution. People applying under the dedicated route for descendants of those persecuted by the Nazi regime are not required to give up their existing citizenship. This is a separate provision with its own conditions.
Retention permits for Austrians. An Austrian who wants to take on a foreign citizenship can apply to keep their Austrian citizenship beforehand. Permission has to be granted in writing before the foreign citizenship is acquired, and it is given only in defined circumstances.
Will the reform change this?
A reform of Austrian citizenship law has been discussed for 2026, with work expected to begin in the first half of the year. As things stand, the proposals being talked about focus on areas like the German language level and an integration course. The general ban on dual citizenship is not being lifted. If you are planning around this, treat the existing renunciation rule as the rule that applies, and watch for official confirmation before assuming any change.
Get advice for your own country
Whether and how you can be released from your current citizenship depends entirely on the laws of your country of origin, and some countries make it slow or difficult. Because the stakes are high, check your own position against oesterreich.gv.at and the rules of your home country, and consider speaking to a qualified adviser before you start.
