For many people it seems self-evident that a child receives the citizenship of its parents at birth. However, this is not always the case, and especially if the parents have different nationalities or if the child is not born in the actual home country, it is worth checking the legal situation more closely. This depends on the national citizenship laws of the individual countries.
Especially if the parents have different nationalities, the possibility of dual or even multiple citizenship may open up for the child. However, the prerequisite for this is that the legal systems involved allow this in each case and, if necessary, that the parents take the necessary official steps in good time and in the right order. Errors here are often difficult or impossible to rectify retrospectively, so timely information in advance is very important.
It should not be overlooked that according to Austrian law, loss of citizenship generally occurs if someone voluntarily acquires a foreign nationality upon application or declaration. This also applies to children if their parents apply for a foreign citizenship on their behalf. A possible way out may be an application for retention of citizenship (submitted and approved in time).
