Dual Citizenship Recovery for Austria citizens in the United States — 2026

Nationality rules differ enormously between countries, and this is not a page that can tell you whether you qualify. Some countries pass citizenship down indefinitely; others stop at one generation born abroad, require registration before a deadline, or do not permit dual nationality at all. What follows is how to find out for Austria, and what to settle before you spend anything.

Quick facts

Austria maintains a comparatively large consular network in the United States: sixteen consular offices, in Atlanta, Bloomfield Twp, Boston, Chicago, Honolulu, Houston, Las Vegas, Los Angeles and eight more. That is a help and a trap at once, and the trap catches more people than the distance does.

Austrian consular offices in the United States

Applications and enquiries go through the career post whose district covers your state, though the decision itself is taken in Austria:

The questions that decide your case

• How far down does descent run? Through a parent is common; through a grandparent is much rarer; through a great-grandparent is unusual anywhere.
• Is there a deadline? Several countries require a child born abroad to be registered within a set period, after which the claim is lost.
• Does Austria permit dual nationality? As a rule, no. Austrian citizenship is lost the moment you acquire U.S. citizenship, automatically, unless retention was granted to you in writing beforehand. This is the one on this page that has to be settled first, and settled properly.
• Does the line pass through either parent? Some nationality laws were paternal for decades and were reformed later, sometimes with retroactive effect.
• What obligations come with it? Military service and tax residence attach to nationality in some countries regardless of where you live.

Documents a claim by descent normally rests on

• Birth certificates establishing the unbroken line, each certified for use abroad.
• Marriage certificates covering every change of surname in that line.
• The ancestor’s Austrian passport, identity card or other proof of nationality.
• Evidence of whether and when an ancestor naturalised elsewhere, which in some countries breaks the line.
• Translations into German where required.

Before spending money on this

Ask the consular office what Austrian law actually allows in your circumstances before engaging anyone to help with it. Genealogists and specialist firms exist and can be useful where records are old or scattered, but they are not a substitute for knowing whether the claim exists at all — and that answer is free.

If your own immigration position in the United States is unresolved, take advice from an immigration lawyer before approaching any foreign authority.

Austria is the exception, and it is strict

Under § 27 of the Staatsbürgerschaftsgesetz 1985, a person who acquires a foreign nationality on their own application loses Austrian citizenship unless retention was authorised beforehand. The loss happens by operation of law at the moment the U.S. citizenship is acquired. No Austrian authority has to decide anything, and nobody writes to tell you.

The way out is a Beibehaltungsbewilligung under § 28. Four things about it decide real cases:

• It must be granted, not merely applied for. The written decision has to exist before you take the oath. Swearing while the application is pending loses the citizenship.
• It is decided by the Landesregierung of your Hauptwohnsitz — for people living abroad, lodged through an Austrian embassy or consulate, which forwards it. Vienna residents and most people born abroad go through MA 35.
• It is discretionary. § 28(1) requires services already rendered or expected, or a reason specially worth considering in the Republic's interest. There is a private and family life ground, but § 28(2) opens it only to Austrians who acquired citizenship by descent — not to naturalised Austrians.
• It expires. § 28(3): the permission is conditional on the foreign nationality being acquired within two years.

The City of Vienna states it without hedging: if you hold Austrian citizenship and take another nationality, you lose the Austrian one automatically, and you must apply for retention before you do.
