Romanian citizenship is regulated under law no. 21/1991 and the Constitution of Romania. The acquisition of citizenship is mainly based on the principle of ius sanguinis and can be granted by birth, adoption or by naturalisation (upon request). Children born within Romania to two Romanian citizens, children born within Romania of international marriages and children born abroad to at least one Romanian citizen acquire Romanian citizenship at birth.
Under Romanian law, Romanian citizens have the right to hold dual nationality and thus can acquire a second citizenship without losing their original citizenship. Foreigners who are granted Romanian citizenship are granted the same rights as Romanian citizens.
In Romania, there are no consequences in relation to the registration or renunciation of original citizenship and dual citizenship is allowed without any special conditions.
