An individual may acquire Slovenian citizenship by birth, or by naturalisation. Slovenian citizenship may be acquired by naturalisation if the applicant has lived in Slovenia on a continuous basis for the prescribed period of time and meets other conditions laid down by law. There is also a process of extraordinary naturalisation, which allows Slovenian citizenship to be acquired under less stringent conditions, where citizenship is in the national interest – in particular, where there are justified academic/scientific, economic, cultural, national or similar grounds. A child acquires Slovenian citizenship if at least one of the parents is a Slovenian citizen at the time of the child's birth.

Applications for Slovenian citizenship must be submitted either at an administrative unit in Slovenia or through a Slovenian diplomatic mission or consular post.

Slovenian diplomatic missions and consular posts can also provide details about Slovenian citizenship. 

Third-party companies that are charging a fee (e.g. EUR 25,000 or EUR 45,000) to assist individuals in obtaining Slovenian citizenship or Slovenian passports are NOT operating on behalf of the Slovenian Government. The official citizenship application fee is approximately EUR 400. Some additional costs may be involved, depending on the extent/amount of supporting documents.

Those looking for information on how to obtain Slovenian citizenship should be aware that unauthorised third parties operate websites advising on citizenship procedures and offering preparation and submission of applications with full sets of supporting documents against certain fees. These businesses and websites are not endorsed by, associated with, or affiliated in any way, with the Slovenian Government. They might operate legally and appear legitimate, but they are deceptive and contain fraudulent information. Official Slovenian Government websites can be identified by the domain name gov.si.

Neither the Slovenian Government nor a Slovenian diplomatic mission or consular post can refund the money paid to a third-party company or website. If you think you have been defrauded, you should contact your bank or credit card company and dispute the charges on your statement. 

Details are available at the only official website providing information on Slovenian citizenship.
