Austria generally doesn’t allow dual citizenship.
Citizenship is granted to the child if:
The parents are married and at least one is Austrian.
The parents are not married and the mother is Austrian.
The parents are not married and the father is Austrian and he has recognized his paternity within eight weeks of the child’s birth or of the court established the paternity within the period.
The parents of illegitimate children of an Austrian father marry after the child’s birth, meaning that legitimation is acquired.
Renouncing existing foreign citizenships and residence in Austria permanently for at least 10 years are required for naturalization.
Legal residence in Austria for 6 years is required, with being married for at least 5 years prior to the application for citizenship.
If an individual who has Austrian citizenship chooses to acquire another nationally and wishes to retain Austrian nationality, they must get the retention approved by Austrian authorities before they choose to pursue an additional nationality.
If the maintenance is in the interest of the Republic of Austria, or if personal reasons are worth considering (the law does not provide for examples of specific reasons that are worth considering but one may think of older relatives living in Austria, career prospects, reasons related to property issues etc.).
According to the EUDO Citizenship Observatory (2010):
In order to prevent the loss of Austrian citizenship when acquiring the citizenship of another state, Austrian nationals must apply for permission to retain their Austrian citizenship (Section 28). If the conditions laid down by the law are fulfilled, authorities must approve the retention of Austrian citizenship. However, authorities have almost unlimited leeway as the requirements to be met are very vaguely defined (Thienel 1990: 302). The law merely states that retention of Austrian citizenship has to be approved if the applicant has performed ‘special achievements’ in the past and is expected to do so in the future or if there is another reason that deserves ‘special consideration’. In both cases, retention of Austrian citizenship has to benefit the interests of the Republic. In addition, the foreign state must not object to the retention of Austrian citizenship and the Austrian national must fulfill some of the general conditions for acquisition of Austrian citizenship such as the absence of criminal convictions.
With the amendment of the Citizenship Law in 1998, a new provision was introduced to allow for retention of Austrian citizenship in cases where a special reason related to the applicant’s private or family life justifies dual citizenship (Section 28 (1) 1). Yet, this new possibility of naturalizing abroad without having to lose Austrian citizenship applies only to those citizens who are Austrians by descent (Section 28 (1) 2). According to the explanatory notes on the draft government bill, the easing of the rather demanding conditions with regard to retention of Austrian citizenship is aimed at avoiding severe ‘adverse effects’ that a person would suffer from the loss of Austrian citizenship. According to information given by some provincial authorities, such adverse effects include severe financial disadvantages, loss of inheritance rights in another state or loss of employment opportunities in both countries. The new possibility of retention is, however, restricted to persons who have acquired Austrian citizenship by descent.22 The reform of 2005 added a further ground justifying the acceptance of dual citizenship; retention of Austrian citizenship shall be permitted if this would benefit the interests of a minor child.
