Losing Austrian Citizenship
Note: The information provided on this page is intended to give a general overview on how Austrian citizenship is lost. Due to the complexity of the Austrian Nationality Act not all specific regulations and pecularities are described in detail. If you need additional information, please refer to the "Staatsbürgerschaftsgesetz" (available in German on www.ris.bka.gv.at) or contact the Consular Department at consulate.london-ob(at)bmeia.gv.at.
Acquiring foreign citizenship:
An Austrian citizen applying for foreign citizenship will automatically lose his/her Austrian citizenship upon obtaining foreign citizenship. Minor children born in wedlock also lose their Austrian citizenship (because of their parents losing theirs).
Entering the armed forces of a foreign country:
By voluntarily entering the armed forces of a foreign country, an Austrian citizen loses his/her Austrian citizenship.
An Austrian citizen both working for a foreign state and adversely affecting the interests and reputation of the Republic of Austria loses his/her citizenship. In addition, newly naturalized Austrians who do not renounce their previous citizenship within two years also lose their newly acquired Austrian citizenship.
Giving up Austrian citizenship:
An Austrian citizen may, under certain circumstances, renounce his/her Austrian citizenship.
